Subject: rv-3 accident
i was out in my garage working on my -4, sub-consciously listining to the -3
doing aerobatics about three miles to the south. nothing out of the ordinary
for this area. while i was listining to the r.p.m. changes, i was trying to
visualize what the airplane was doing. at what must have been the final
moments, i heard his rpm go way beyond what would seen to be normal and then
i heard the rpm's immediatly drop back to an idle condition. almost sounded
like a he had just gone over the top of a tight loop with power off down the
backside. i thought to myself, man, he really pushed that one. in less than
five minutes i heard my fire radio report an aircraft down...

Has anyone considered the option of simply not flying in this fashion? I
question whether it is strictly legal from the view of the regulators.
I may be a bit too conservative, but you really have to pay attention to what
your doing up there. You just can't go out and fly with reckless abandon. At
least if you want to keep flying.
On the subject of balistic chutes Van doesn't seem to be in favor of them.
On the subject of ejection seats geez, the military has it's hands full
maintaining those things.
On the subject of instrumentation. You might want to add some sort of strain
gauge to the wing spar. This could be set up to detect cumulative wear and
perhaps detect deterioration in the condition of the wing before it actually
failed.
I am reminded of a Navion I saw which had been landed hard with the tip tanks
full. Broke the wing. Pilot didn't notice the broken wing until he flew it in
to a mechanic for it's anual. It was amazing. The wing would flex a couple of
inches. I don't know if monitoring the deflection of a wing via straing gauges
would really let you measure and evaluate the state of the wing as the hours
built up.
Much simpler to fly conservativly and not get in questionable situations where
you have to push the airframe and pilot to their respective limits.

Quite frankly people, ballistic chutes are not going to do you any good at
the speeds a RV is apt to be flying at breakup. All of the warning bells and
whistles in the world are not going to do you any good if you do not fly
within the design limits of the airplane. In over 700 hrs of flying in my
RV-6 I have probably done some stupid type of flying but I have always kept
in mind DO NOT DO AN AGRESSIVE HIGH SPEED TURN AND CLIMB as someone mentioned
here high speed, turn and climb create high G forces very quickly and
failure could occur before you had time to react to any bells or whistles.
A ballistic chute might be fine if you are over rugged country with no place
to land if a engine failed it "might" let you down a little easier.
Van and Steve were flying towards each other and as they passed each other
started a turn when Steve start making the turn tighter to get behind Van,
Van started a climb, we can only assume that Steve being at a high speed and
a tight turn started the climb also which would quickly created a high G
load.
Please all fly safely.

Cheryl,
Nice dogfight. I'll just throw in my two cents on the G warning.
As discussed, we are making this way too complicated. If there is gonig
to be a warning,it should go off at 6gs. If the warning goes off, you
immediately LET GO! Forget the Glasair.
6gs is the limit. Van did not pick that number out of a hat.
See you tonight..

Sounds like a neat gadget but why not use it as a training tool...
After a couple thousand hours of tactical flying I will agree that an
alarm can be useful when your performing a mission in low altitude
high G environment. Alarms like low altitude warnings and rudder
shakers can get your attention when you've been distracted by the
cockpit workload.
My point is pulling acro in an RV-3 is likely the "primary mission".
One who is engaged in such activity needs to know what 6.5 G's feels
like while having the situational awareness to recognize things are
getting out of control.
Why not design it to go off at 4 G's so you can react to it.
In this case it would be a nice training tool to calibrate your but to
the G- meter.
After relatively little time one can "feel G's" to a very high degree
of accuracy.

Subject: RV-List: G warning
Date: Wednesday, October 11, 1995 12:42
I spent a lot of time thinking about this wing failure stuff
last night. This is particularly relevent as I am just puttting up
my wing jigs for my -3A.
So here's an idea. How about a G warning. It would be an
audible and visible alarm. It would make some nasty noise that
would increase in both pitch and volume as the G load exceeds a
preset value. I would preset it to start at probably five Gs and
increase every half G. Once I got to 6.5 it would make an awful
racket and be wildly flashing a red light on the dash. At least
this way if I was yanking and banking and having so much fun
that I was lost to reality I would get a serious reminder.
A G meter with an electric output would be needed along
with some electroncs. I should be pretty easy and really could
save someones life.
Thoughts?

Subject: | ProSealing tank baffle |
I'm following George Orndorff's procedure for prosealing my tank and I just put
on the back baffle. I've installed my wood pins to seal the skin to the baffle
above the rivet line and it occured to me that I after smearing seal over the
shop heads of the 3/32 rivets and with the sealant oozing out under the wooden
pins it's going to be tough to get the baffle over the spar flange where all my
nutplates are. If there is sealant on the baffle flange in the area where the
csk #8 screws attach to the spar flange won't it be tough to get a good fit?
Will the tank stick to the spar? Do I have to remove the sealant from the tank
baffle above the 3/32 rivet line? Will the wooden pins come off the baffle once
the sealant cures? Does any of this make sense?

I don't think it's that he is not in favor of them, I believe it conflicts
with his idea of the the RV represents. (light sportplane with respectable
performance and low cost) As well as analysing were the largest % of
accidents occurr. (Low altitude manuevers that probably wouldn't have been
saved even with the chute because of excess airspeed at such a low altitude)
Just my opinion
>On the subject of ejection seats geez, the military has it's hands full
>maintaining those things.
I new the question was way out there, but I just wanted to get some feedback
as to what was available. I could just picture the many issues surrounding
an ejection seat in homebuilts. You would probably see a few reports of a
pilot (un-expectedly) ejecting from their perfect aircraft that was happely
flying straight and level at 8000 MSL. Or the FAA wondering if it was
really necessary under the circumstances for a pilot to eject while the
un-manned aircraft takes a nose dive into someones house.
>Much simpler to fly conservativly and not get in questionable situations where

The words 'questionable situation' could be argued for centuries without an
agreement as to their meaning.
In my opinion any aerobatic maneuver is a questionable situation (not
necessary for simple point A to B flying) But if that is all I wanted in an
aircraft, I probably would have bought something other than an RV. Since
the ac has such fine flight characteristics, I want to exploit them by
flying some very basic aerobatic maneuvers.

I wrote it _wrong_, too. At the speeds we're talking about, if you
start with calibrated airspeed, the result will be an accurate
estimate of calibrated airspeed. Start with true, get an accurate
estimate of true. Dang, I hate it when it does that.

How do you know you're at a limit by just listening to the tone?
You've got to have a calibrated ear to know what volume level and
tone correspond to the knock-it-off limit. In addition, if this is
intended to save you from the 'dogfight' type of overstress, the
flashing light won't help you, because (if you're doing it right)
your eyes will be on your opponent, not the panel. It won't stop
the panic-type overstress either, because, given the choice between
(at least as far as your brain is concerned) definately smacking
into the ground or maybe overstressing, who wouldn't choose the maybe?
I vote for the 'calibrated butt' warning system. If I have to
start straining, or straining harder than I'm comfortable with
(and it takes practice), it's time to unload some of the g. Guys
fight with faster airplanes with similar g-limits (sometimes
lower) above corner speed (Va) and use this method, only they're
sometimes fighting for real.

I'm not familiar with the F-15 specifically, but I'd be willing to
bet that there's no 'g-warning' as such. Similar airplanes have a
g-limiter and an aural AOA cue. I can't think of a way to shut the
AOA tone off without pulling breakers (bad). A properly designed
g-limiter in the RV's could solve all of these problems. Just the
project for an electrical/aerospace engineering team. Earl, Matt? :)

My point was that the structural failure of a wing is most likely
not a result of the pilot losing consciousness. The same thing
that causes the failure may induce GLOC, or the dynamics after
the failure may induce it.
>GLOC is not something that happens instantaneously.
Again, this is highly dependent on physiology and technique.
A gradual application of g will cause the symptoms you describe,
and they can be delayed by the doin' tha grunt (assuming you're
trained well enough to do it), but rapid g-onset and/or an
unattentive pilot can lead to almost instantaneous GLOC. (Been
there, done that, in a rather embarrassing 6-g break turn).

Good point, I'm just about ready to start some Pro-Seal evenings myself and
my shop heads are basicall touching the spar flange. If I add a layer of
goop, I will surely have to trim that spar flange by a 1/16". Is that doable?

I agree. But if I want to be conservative I would stick to a certified
aircraft with certified engine and only fly CAVU, never pull more than
1.5 Gs, never exceed Va, always fly fixed gear, never let fuel go below
3/4 full and always fly within gliding range of an airport or interstate.
I do this now in my clubs Cessna 172, if I were happy doing this I would
not be building an RV-6. The only possible reason I would have for
building a single
seat vfr high speed/maneuverable aircraft would be to fly aggressively.
By aggressive I do not mean to exceed 6 Gs, but aerobatics/dogfights? at
3-5 Gs would be aggressive flying in an RV-3 and insane in a C-172!
Conservative is a relative term, just like common sense. I have never
met anyone who will admit to not having common sense! IMHO the type of
person who builds and flys an RV-3 is not a conservative type of pilot. I
do not consider anyone that does acrobatics conservative and the RV-3 was
designed for many of the aerobatic maneuvers. You can't design and build
an airplane such as the RV-3 and expect the pilots to never fly
aggressively.
But as we are often warned: there are no old bold
piolts! The penaly in the air for a mistake is often quite harsh! Just
my thoughts.

I like the 4 G warning. Also wanted to point one thing out, even though
it's probably obvious. 6G is only valid at aerobatic weight. Take your
weight above that and the G-Max goes down.

Subject: RV-6 throttle placement
An article in the current AOPA Pilot indicated the Air Force trains
pilots in the right seat of the Firefly (T-3A). They don't want the
pilot to change hands on the stick for work the flaps and the
throttle.
I've heard of a couple RV-6s set up to solo from the right seat. I
guess this may be the same reason...
I was wondering if anyone has put the throttle on the left side of the
RV-6 cockpit. I guess you could put the flap control (electric only)
there, too.
An immediate reason for not doing it... I become incapacitated and my
right-side passenger has to fly. It would be awkward (at best) for
him or her.
Though I haven't had any experience with this, it just seems "right"
to keep the stick in my right hand....

Yes you will need to remove all of the proseal that oozes out from the
back baffle of the fuel tanks in order for it to fit to the wing
properly.
The best way to do this is to rivet the thing together, then clean it
off well before you install any clamps. The clamps shouldn't end up
generating much more "ooze" if you have already cleaned it after
riveting, and should be relatively easy to clean off with Lacquer
thinner after a day or two of curing, but don't wait 2 weeks or it will
be a bear.

True,
F-15's do use aural warnings. There is a 900 Hz tone interrupted at 4 Hz when
at 85% maximum g, at 92% of max g it is interrupted at 10 Hz, until at 100% of
allowable the voice warning "OVER G" is announced until the g is reduced within
limits. The pilot can't turn it off , but he can make an error programming the
computer about configuration and cause faulty missing g warnings. One concern I
have is there has been no discussion of symmetrical (straight pull or push) with
un-symmetrical g loading (Rolling and pulling). During a rolling maneuver the
wings experience vastly different loads (one at a higher g load than the other).
Because of this, there is a significant reduction in un-symmetrical g's (rolling
g's) allowable in most military fighter. For example, at a medium fighting
weight, the F-15 can pull 7 g's symmetrical and only 5.8 rolling g's. I would
assume this is true for RV's as well.

Guys!
I just reviewed this with George. We are pretty sure on the tape he
referred to using masking tape to cover the areas here that you wouldn't
want to get proseal on or the tank won't fit over the spar. The masking
tape can be removed after the proseal is set.
If you have gotten proseal on the skin that will go over the spar, you
will have to remove it with a putty knife or (eek) a razor blade like a
window scraper. You must be very cautious doing this so as to now gouge the
aluminum. If you do scratch or gouge, use emory paper to smooth the scratch
so there are no sharp edges that could cause stress cracks in the future.
We're really sorry you missed this point and hope the damage isn't too
bad and doesn't take too long to fix. If you need further clarification,
please call us in the evenings. We'll spend as much time as you need to help!

Jerry,
I'll respond here publicly because the discussion may be interesting to others.
I totally disagree with your statement that GLOC does not happen instantly.
That is not totally correct. It all depends on the g ONSET rate. Maybe in your
T-38 the rates (not limits) weren't high enough to cause instant GLOC, but I
went from fully awake to TOTALLY unconscious in less than a second without any
warning in an F-15 (single seat!). The g onset rate was extremely high,....
right up to 8+ g's. Luckily the maneuver was a pitch-up into a bandit ( if it
had been a nose low slice I wouldn't be here today). I started the maneuver at
15,000 ft at 450 kts. I woke up at 26,000' 320 kts 30 degrees nose high. My
G-suit had come disconnected (this was before they modified the connections to
prevent this from happening). It is much more than g load, it's also g onset
rate and duration.
I fully agree that there are a lot of pilots "yanking & banking" that may not
fully appreciate that rolling (unsymmetrical) g's impose MUCH higher loads on
the airframe. These loads don't show up on the G meter. With a +6 g airframe
(+9 ultimate) I would never consider moving the stick left or right from center
(rolling under a load) if at more than 4 g's!

Greetings:
I'm Howard Kidwell a new subscriber with a RV6 under construction. I am a
retired USAF Fighter Pilot and have been building about 2 years. Not much
this year, but have just retired from State Govt. and should be out now
working in the "hanger" (garage). I have finished the tail and one wing is
about completed so you can see I have a way to go. I live in Austin Texas
with Mr. RV "TONY B" and lots of flyers/builders, but of course they live/fly
30 miles from me. Looking forward in sharing thoughts and info.

Don't panic. You can remove the wooden clamps after 3 days or so. At this
point the proseal will still be a little soft and fairly easy to remove.
I generally use my thumbnail to scrape it off, but a wooden popsicle stick
or a plastic scraper would work also. Even fully cured proseal can be
scraped off with a bit of effort, but in my experience, a full cure takes a
couple of weeks. I find that laquer thinner will remove the proseal even
after a day or more of curing, but my workshop is fairly cool (~60 - 65
degrees) so this probably slows the curing process somewhat.
The wooden pins will come off easily, at least mine did, even after 3 or
four days of curing. You *do* need to remove any excess proseal from the
spar mounting area up to the 3/32 rivet line, but as described above, it
is not difficult if done while the proseal is still reasonably soft.

During all the talk about G force warning systems aerobatic maneuvers and
whatever else talked about in that last couple of days, I thought some of
you might be interested in a fantastic new simulator that is available right
now for FREE on your PC. This simulator is for those of you who like a good
dogfight. If you are interested, read on...
The simulator is called Confirmed Kill and is played online with the
Internet. The system can handle up to 500 simultaneous playes. The reason
it is free, is because right now the simulator is in the Beta stages and
they welcome people to come on board and give it a try. (Especially the
real pilot types) What this sim offers is right now is the selection of the
following aircraft: F4U, P-51 'Mustang', Zero, P-38 'Lightning', Spitfire,
Me109, P-39. As the game progresses they will be adding support for about
50 other WWII aircraft including the Me262 (jet).
You might be wondering just how realistic the simulator is? This is what I
asked, since I've been trying simulators since the Apple II days. This is
one of the few simulators for PC's that use force models. In simple terms
this means is a very realistic representation of flight qualities. Most
flight simulators use tables that say, if plane is traveling at speed X, it
behaves in this fashion etc etc. Not very dynamic. A force model uses
simple calculations of drag at given altitudes and forces from thrust. Fuel,
ammo weight, Gear drag etc.. Granted this is not a full blown wind tunnel
on your PC, but you can simplify the complexities of wind tunnel
calculations and get a fair representation of flight. High speed stalls,
tail slides, knife edge flight. You have to compensate for engine torque
and P-factor. (you can even buy Rudders, throttles etc. if you get really
hooked) Right now the planes in CK aren't locked into the final flight
models, (some of the aircraft are horrible), but The P-38 and Zeke are
pretty good. The P-38 handles Energy a little too well, and the Zeke is a
bit too tough, but each release fixes problems.
When I said dogfighting, you would be absolutely amazed at the
adrenaline rush you can get on a simulator!! Fighting against other human
beings is a lot of fun. You get a pretty nice idea of what can happen in
aerobatics if you aren't careful. Take the P-51 near 500mph and you'll
enter compression, and more than likely auger into the ground. The system
handles blackouts, grey outs, red-outs etc... It also has one of those
progressive sounding AOA indicators. (audible alarm, kinda like the audible
G meter suggested in previous discussions)
The damage model is also fairly realistic, (it's getting better with
each release). If a round comes through the canopy, you'll probably be
killed in flight. If the lead punctures the fuel tank, you'll either
explode or be leaking fuel. Engines get knocked out during head ons etc.
You can even shoot someones wing off, and watch the aircraft go spiraling
out of control. Load up with fuel fuel and ordinance and you'll take up the
entire runway and then some. Fly a P-51 below 200mph and you have one
squirly machine. All in all they did a respectable job. (And this is
coming from someone who has never been impressed with a PC based flight sim)
Flight sim 5 is the best I've flown, but a bit boring to me. I think CK
appeals to the testosterone in me.
If at least one person is interested in this just post your interest and
I'll post the instructions for getting involved. (remember its free until
the simulator is released on the market)
Right now, If you don't have at least a Pentium 60, it's not worth trying.
In the next couple of days, they will have a version that handles a 486-33
just fine.
The Sim supports screen resolutions from 320x200 to 1024x768!!!!

I started flying in gliders and the "throttle" (spoilers) are on the left
side. Most tandem seat acro trainers also have this setup. I also feel more
comfortable with the stick in my right hand. I considered installing a dual
control throttle. A cable arrangement is what I decided would be best from
a pounds point. The only problem that I have is that things like this tend
to get more complicated than one would think. When it comes to airplanes I
like simple. If you come up with a solution be sure to let us know.

Hi all,
I'm a 53 year old who's been flying since age 16. 2000+ hours, mostly in
Citabria 7ECA. I can see where I will have the time and money to get started
on a plane in a few years - kid just getting started in college next year. I
was thinking of going the Glasair route but got interested in RV after I saw
the RV-8 in the latest Sport Aviation. I seriously think I would miss the
centerline seating and left hand throttle control with the Glasair. I also
wonder whether the extra 50 mph is worth the extra cost and complexity. I'd
like to do a real nice above average job, but don't have the patience to do a
4000 hour show plane. I consider myself a pilot first and a builder second.
I'll just be sitting in the background here soaking up the info. I live in
Minneapolis and might be interested in going into a group where several of us
could share tooling. After this latest thread, I'm real interested in the G
limits of the RV-8. I would often pull 5 G's in the 7ECA during cuban eights,
and that was a much slower plane where trouble was less likely. One thing
that hasn't been mentioned so far is turbulance. It's fairly easy for 5 G's
to become 6 if the air isn't smooth as glass. I consider myself a fairly
conservative guy who likes excitement but not danger, so I have (almost)
always done acro at 4000 feet above the inversion layer.
Thanks for letting me listen in.

I have had this problem on both my tanks, in spite of my feeble efforts
to measure the rivet line accurately enough to allow clearance. On my
first tank, I just filed down the spar web flange until it cleared all
the tank baffle rivets, making sure that I maintained the minimum rivet
edge distance for the nutplates while doing so. On my second tank, I am
trying a different method:
With the tank mounted on the wing, I took a carpenter's square
and marked the location of all the tank baffle rivets, *on the aft spar
flange*. Then I removed the tank and again using the carpenter's square,
remarked the position of the tank baffle rivets, this time on the forward
spar web flange. Then, using a round file, I made little scallops in the
flange to give clearance for the baffle rivets. This seems easier than
filing down the entire flange, and has the added benfit of only removing
metal from the flange where it was necessary, leaving plenty of extra edge
distance for the nutplate rivets in most cases.
While worrying about this edge distance business, I did a little
calculating regarding just how much load each tank mounting nutplate has
to bear. The results were surprising.
The RV-6 has a gross weight wing loading at aerobatic weight of roughly 12.3
lbs/ft^2. The fuel tank has 6 ft^2 of area and must take a 9 G load
factor at aerobatic weight, so:
6*12.3*9 = 664 lbs.
This is the maximum aerodynamic force to be supported
by the wing tank. Note that any fuel in the tank will add loading in the
*opposite* direction and thus full tanks give less overall loading than
empty tanks! This is obviously a good reason for mounting fuel tanks in the
wings.
Now if we ignore the tank-to-fuselage mounting bracket and also ignore the
outboard tank rib nutplates, then we have (I think) 28 nutplates
attaching the tank to the top spar flange and another 28 attaching it to
the bottom spar flange. Now I'm not sure where the mean aerodynamic force
is applied to the tank under high G-loading, but lets say its at 50% of
the tank chord, about 9 inches from the leading edge, and evenly distributed
along the tank span. Since the wing spar is also roughly 9 inches deep
(I'm just guessing here), there is no force multiplication through leverage
and the lower 28 nutplates would see, at 9 Gs, full aerobatic gross, a
total force of 664 lbs, or 23.7 lbs per nutplate! This is only 12 lbs per
rivet, worst case! And, this does't account for part of the load being
taken up by the tank-to-fuselage bracket and the outboard rib nutplates.
Properly installed 3/32 rivets with the minimum 2 D edge distance can, if
memory serves, support at least 180 lbs before failing, so these nutplate
rivets are really under loaded.
Conclusion: Unless I have made a grave error (pun intended), there is a
**LOT** of redundancy here, so I wouldn't worry too about trimming the
spar flange a bit to clear those baffle rivets. Try to maintain that
minimum 2D edge distance in any case.

I am also thinking of a left hand throttle in my -6, assuming that it
works out ergonomically (I havn't started my fuse yet). I have seen a
Zenair side-by-side with dual throttles. They were knob-and-cable tpye,
like a Cessna. I think the most difficult issue would be the friction
lock. You obviously couldn't use vernier cables as one throttle would
lock the other. I was thinking of a throttle lever on the left side and a
knob throttle in
the middle, with the friction lock removed or disabled from the knob, so
that the friction lock of the lever would control the whole system. I
would either connect both cables to the carburettor directly, if
possible, or else connect them to an intermediate bellcrank of some sort,
but this starts adding weight, complexity, etc.

Russ,
We have the throttle and other controls center console on our 6-A's and
I have flown and landed from both seats. You adapt pretty quickly to
whichever seat. We built the 6 rather than the 4 so we could both fly and
both have control in case of emergency. Safety if pretty high on our list
of priorities. I think some of the 6's are set up for right seat operations
as right handed people feel they have better control of the stick with their
right hand. Good luck with your decision.

Reply to: RE>>RV-List: G alarm thoughts
Steve, if you count the research and development; starting in the late 40's by
the military on the rocket propelled, 600mph, water brake sled and all of the
activities continuing even today - the probable development $$costs for
ejection seats are greater than $500 million! The rocket sled alone could not
have been built for less than $25m. To top it all of we don't even use a US
designed seat - its British!
Even if you strap a home-brew apparatus to your GTO and do 150mph test runs
at Bonieville - it will take you a lifetime of development. And if you had
the money you would buy a TBM700 or (insert your favorite here). By the way -
who is going to be the very FIRST, live, human to volunteer for that 200 mph
departure test! If its not you - what insurance company is going to cover
your test pilot - do you have enough for the premium!.
If we want to help the most pilots the focus should be on what is practical,
doable and affordable now. IT CAN BE DONE - more later.

Bob,
I meant to write to you earlier to thank you for your response. With regard
to the shelf paper method, I imagine that you just drill through it, but how
do you deal with dimpling or countersinking? Do you just avoid applying any
paper in areas where you expect to do these things? Dimpling is one of
those tasks where I seem to get the most scratches unless I pay very close
attention when I move a skin around on my "C" tool and I would dearly like
to eliminate this problem.
I had read about this technique in the RVator reprints from Avery but I
assume that one shouldn't dimple over the paper. I figured that it would be
too much trouble considering this dimpling issue.

If you want the throttle on the left, wouldn't it make sense to just make
the right seat the pilot's seat? I've seen RV-6's this way before. It seems
a lot simpler than dual throttle controls or anything like that. Nothing
says you have to sit on the left - that's one of the benefits of building
it your self. Just a thought...
BTW - my left wing is FINALLY done (don't ask how long I've been working
at it)! Ah, the simple pleasures of life...

Regarding the left/right throttle discussion:
People feel comfortable with what they are used to. But unless you have
had some time flying a particular configuration, I would be hesitant to
decide you are never going to like it. I'll bet it would be a lot
easier to get used to a new configuration than to deal with building up
something special in your RV, not to mention the hassles with having a
passenger take the controls, or the potential reduction in resale value
for a non-"standard" RV configuration.
I learned how to fly in Cessnas. I then took up taildraggers, both
Champs and T-craft. I currently fly a Citabria (stick in right hand,
throttle in left). I have about 20 hours of left seat time in RV-6/
6As. I have never found it to take long before a new configuration
feels natural, and once I'm used to a particular configuration, it
takes no time at all to switch to a different one that I am also used
to. I can climb out of the Citabria and into a Cessna or RV and feel
right at home (well almost, 20 hours isn't much).
Of course everyone can and should build their RV the way they like it,
but in my opinion the standard configuration works, so why mess with it.

I learned to fly tail dragers in a Luscombe 8A which is side by side
with a stick and had the throttle in the center. You fly it with your
left hand on the stick and right hand on the throttle. I was very comfortable
with that as I started flying in a Cessna 150 and it was very similar,
except a stick instead of control wheel.
When I started flying biplanes (Acro Sport and Pitts), I thought I would
not like the throttle on the left and the stick in the right hand.
However, you adapt quickly and now that seams 'normal'.
So, I think you should not worry about the throttle in the center as you
will adapt to it quickly. If you every sell the plane, that is also
the most common location for side-by-side so anything different will be
viewed as unusual.

Good point! In fact, it's not unheard of for ONE G to become FOUR Gs --
I hit a 3.5 G "bump" recently, flying in otherwise light turbulence
over mountains. Don Wentz told me he once hit a FOUR G bump, in
otherwise perfectly smooth air, as he crossed the low hills between
Scappooose and Hillsboro. That'll wake you up for sure!

Good point, I'm just about ready to start some Pro-Seal evenings myself and
my shop heads are basicall touching the spar flange. If I add a layer of
goop, I will surely have to trim that spar flange by a 1/16". Is that doable?
I am in need of the same help as you. Please, someone educate us. :-)

(CK ID - RV6a RV for short)
Scalloping the spar flange is the way to go. You have to transfer the rivet
locations onto the flange, but filing the flanges with a rasp only took 30 mins
or so. And masking off areas beforehand is much easier than taking pro-seal off
afterward. I don't remember having the luxury of couple of days of "uncured"
pro-seal. It was about 90F in the garage and I made sure I cleaned up everything
before retiring for the evening. Pulling the masking tape off about 3-4 hours
after mixing the Pro-Seal seemed optimal.
And is everybody putting in the doubler by the wing root rib where the fuselage
attach Al angle mounts. I didn't, and I probably will not, but it is on the
latest plans.

It measures the pressure in the manifold, of course :).
A MP guage will show the normal atmospheric pressure with the
engine off. I.E. 29.92 inches of Hg. for example.
Therefore the MP is measuring the pressure of the air in the
manifold relative to zero pressure.
When you start the engine and it is idleing, there is a
high 'vacume' in the manifold so the MP will show a low reading,
lets say 12 to 14 inches. This is due to the pistons trying
to suck in air but the carb throttle plate is closed and is
restricting air, so you get a 'vacume'.
If you don't have a low reading at idle, then you have a leak
somewhere in the intake system or you have a week set of Jugs.
If it bounces around a lot, maybe you have one poor cylinder.
As you open the throttle, you now have a lot more air going
into the manifold so the MP goes up. It will usually never
go back up to atmospheric pressure as the engine is sucking it
in as fast as it can.
As you climb to altitude, the MP will also drop.
If you have turobo charging or super charging, then you can
get the MP to exceed atmospheric pressure. For example, the
waste gate may limit max MP to 34 inches or some such number.
With a CS prop, you can open the throttle all the way open
and allow the engine to breathe easier and then control the
RPM with the pitch of the prop.
What am I talking about, I don't have a plane with a MP guage.

The shelf paper is clear and I write on it mark it and drill
right through it. I also just dimple with the paper on and before
riveting I use a hand held deburr tool (as seen in the Orndorff wing
videos) and do precisely two complete turns. This cleans out most of the
shelf paper in the dimpled hole before I rivet. Once the completed
section is riveted I store the whole thing with the shelf paper still on
it. The paper is not really paper but thin plasic. I gives good
protection from small scratches but won't do a thing for you when you
drop your bucking bar on the aluminum. (Of course I've never done this,
and hope not to do it again!!). No problem with scratches from the C-tool
and if you counter sink, the countersink will clean out all of the
plastic. So far I have not had any problems with this technique.

Subject: | Re: Balistic parachutes |
I have not seen any RV's with balistic parachutes.
BTW, Second Chantz has converted their "balistic" parachutes to
use compressed air to blast the chute out.
They said that the explosive was a real problem having to ship it
and having the customer to send it back every few years, etc.
I got some info from Second Chantz when I presented at our local EAA
meeting on parchutes (mainly pilot emergency rigs).
Second Chantz (?sp) had some interesting stories on acutal saves
that were documented. Most are on ultralights. There, they have to
deal with the lines going thru the prop as many have pusher engines.
They appear to use a pair of steel cables for the first 10 ft. or so.
For a RV, I think you would have to mount in the fuselage in the baggage
area or just behind the baggage area just under the fuselage skin.
This would shift the CG aft. If it was in the baggage area, it would
reduce the total baggage weight allowed.
I think the attach cables would have to be routed so that they would
be secured to the main spar center secion. I don't know how to
route the cables to do that, but I think it would have to be attached
to the main spar somehow. Anywhere else could tear thru the aluminum.
The problem would be with the cute opening the cables would pull up
thru the cockpit and might do bodly harm to pilot and passenger.
This is much easer to solve on a high wing aircraft.
On a RV3 or 4, you could route these cables along the top longeron
stiffners in the cockpit (hide them under some cloth or plastic)
and then down to the main spar at the main 404 bulkhead.
When the cute would open, it would tear off the canopy as these lines
are pulled tight. Small price to pay.

Actually, aside from the habits formed by left hand drive cars, there's also
the matter of visibility in the pattern. Most US airfields have a left hand
landing pattern (I can't vouch for Europe, but I don't see why it's
different).
It is an interesting transition. I learned in a TaylorCraft and a C-150. I
held the yoke with my left hand and the throttle with my right. Then I tried
out the Aeronca Champ, with a stick and the throttle on the left. I don't
have a real strong stick in the right hand habit built up yet. Who knows.
Hey, thinking about that flap/trim discussion from a while ago, how about a
servo operated throttle?
Put down that bucking bar! It was a joke! Aieeee!

I think you folks are now starting to see the problem with the light/aural G
meter. It is only concerened about PISF (PILOT induced structural failure).
Why not protect against ALL CAUSES OF FAILURE.
If I intercept that mallard at 200 kts (subtract15 duck kts if he is going the
same way) I'm just not going to appreciate that light stating the obvious on
my way down. How about CAT (clear air turbluence), a mid-air collision, or
prop/engine failure causing loss of parts and the unrecoverable cg changes.
Granted, how many of these things were there last year. However, if you want
any chance to survive ALL structural failures (regardless of cause) - a
balistic chute is your only hope.
Keep an open mind - give me a chance, more chute info later.

Subject: | Cockpit set-up - left throttle |
RV-listers,
..... after much internal debate (at least I don't lose any
arguments with myself!) I have decided that I too want a left
throttle/right stick arrangement. As early poster noted, gliders come this
way (I have more glider hours - 800 hours with a real stick - than power
hours at this time) .... but what he didn't mention is that the few
side-by-side gliders that exist are actually set up for right side pilots
(and some helicopters too I believe, if they have a single collective lever
in the center).
I decided the easiest way do do this is to make my RV6A a right
pilot set up. A few simple modifications should allow this, and if I ever
want to sell, it will only need a new instrument panel made up to revert
back to the normal spam-can setup. What I have done, or am planning is the
following:-
1. Make both sticks removeable. Both of my sticks are now 1 inch diam.,
and slide into L & R bases similar to the Wd-611 weldment. I used a short
internal 4130 sleeve in the sticks and 4 rosette welds to hold this sleeve
in place. Both will get PTT switches built in. For flight purposes, only
one stick will be removed at a time :^)
2. I bought Vans right side brakes option, but am going to use -3
metal-braided teflon hose between the two sets of actuators instead of the
Nylaflow tubing for increased reliability.
3. I will leave the canopy latch assy. on the left side (I'm building a
tip-up) since it's easy enough to reach across the cockpit. The overhead
canopy latch will act as a safety back-up if a dumb passenger opens the
side latch in flight!
4. I will move the canopy jettison actuator mount channel to the
centerline of the F-668 sub-panel. This should just about give enough room
for a 6.25 inch radio stack to be installed to either the left or the right
of the center. I am assuming that my radios will be longer than 6 inches
:^) and that this sub-panel will have to be drastically cut away for the
radio stack. The plans/instructions give no mention of this, perhaps one
of the flying guys with a tip-up canopy can give more information on this?
The future Terra remote-head avionics might remove this problem.
5. Since I have electric trim, I am omitting the instrument panel central
"pillar" and will mount the throttle/mixture/carb. heat on a small
horizontal sub-panel under the center of the instrument panel. With the
newer hanging rudder pedals, I think this give the cockpit a very 'clean'
look, with a flat, uncluttered floor (except for the -6a gear leg mounts).
6. Steps on both sides ... see the earlier nose/tail wheel postings :^)
7. I will allow enough slack in the instrument hoses and wires so that
they can be located on the other side of the panel at some future date if
needed.
I believe the above changes will give me the ability to get a left
throttle/right stick arrangement that can be easily reversed in the future
by just fabricating a new instrument panel.
I welcome any sensible comments and am particularly looking for any
"gotchas" that might pop up, or items I may have overlooked.
... thanks for any help ..... Gil Alexander
PS. one of the Oshkosh Champion planes a few years ago (Glasair?) was set
up for a right seat pilot.
PPS. I checked FAR 23 to see if there was any requirement for certified
aircraft to be flown from the left seat. There is not, and it even
specifies the order of the engine controls on the panel.
PPS. I'm definitely not a lefty. Last time I tried drilling with my left
hand, I made a #41 hole in my right thumb nail! Funny enough, it didn't
even hurt.

REGARDING PARACHUTE STUFF
Now that the ejection seat has been thoroughly thrashed - what' so good about
a chute? Well... its affordable, it WILL work and the development,
engineering, and learning-curve have been paid for by someone else - ain't
that special!
I'm not minimizing the heartburn necessary to adapt to a rv-n but look at the
facts. If only 10% of you builders find merit in the idea - thats a lot of
good ideas and market potential. So no sermon - just the facts - you be the
judge.
(1) Forget the speed limit stuff. A chute can easily survive 2X any speed the
rv will ever see. BRS and Cirrus are both engaged in adapting a chute to the
SR-20. The current deployment speed limit is 200kts (not mph)! That plane
will gross at 2900 lbs! Sure there is development to do but you are NOT PAYING
for it! I saw the Cirrus mock-up at AOPA, Palm Springs last year and those
folks are serious. Some astute engineering and thought has been given to
load-paths and survivability.
Consider that chute deployment on a top fuel dragster pulls a momentary 12 g's
on a 2050lb vehicle traveling 312 MPH! Of 4,000 passes last year (top fuel
only) I never heard of ONE chute failure! If you add other classes (all
greater than 250 mph) there was probably 6,000 MORE deployments with NO
failures! (data available on request). So forget the materials problem - it
is irrelevant - a parachute can EASILY SURVIVE rv cracking velocities!
Yep, load path, structure, packaging, cg, are all critical but why continue if
you all think it is hopless. It isn't... so more facts later. I'll wrap it
up in the next letter.

vernier.
The only thing I really had to overcome was the friction control on the

If you learned to fly in a tandem you had the stick in your right and

The issue comes down to the handedness and preference of the pilot.
There is no "right" or otherwise about it.

Howard,
Wipe your surfaces down with Coleman lantern fluid. We found this gives
a cleaner surface than laquer thinner. We use about 45# for our spray gun.
This varies from gun to gun, check the specs with the gun. You will be
spraying a very thin coat. If you have pen marks on the aluminum that
survive the Coleman, you should be able to read the marks through the
vari-prime. ***And, be sure to wear a respirator***

My name is Mark LaBoyteaux and I'm building an RV-6a. I started
construction in October of '93. I have completed the tail and wing sections,
and have the fuselage jigged
and I am starting to attach the aft skins.
I am currently employed with American Airlines as an avionics maintenance

Subject: | Fuel Tanks and Spar Flange |
With all this talk about filing to make room for tank rivets etc, I
thought I would remined everyone about an article writen by Van in the
Dec. 1993 RVator. He cautions strongly against doing anything which
would scratch, nick, etc the spar flange strips. Here is part of that
article.
Van writes, Dec. 1993
"Lately we have had a number of questions about damaged spar flange
strips. Builders have slipped while tapering the strips on a saw, or
have accidentally drilled holes through the spar web into the edges of
the flange strips on the other side. One builder decided that he would
extend the rear row of screws attaching the fuel tank all the way to
the fusealage, so he ground several notches in the flange strip to make
room for nutplates. Oh, boy! Anyone for a nice game of Russian
Roulette? Anytime a seemingly minor glitch occurs on a spar it is like
a lifeline cable in the suspense movie; another strand has just
broken."
"Do NOT arbitarily grind away anything on the spar flange strips.
Repairing a damaged flange strip is impossible: you can't just weld a
hole closed or daub a patch over it."
"Don't arbitrarily do anything to the spar which isn't in the
instructions."
Be careful out there!!!!

REGARDING PARACHUTE STUFF
Now that the ejection seat has been thoroughly thrashed - what' so good about
a chute? Well... its affordable, it WILL work and the development,
engineering, and learning-curve have been paid for by someone else - ain't
that special!
I'm not minimizing the heartburn necessary to adapt to a rv-n but look at the
facts. If only 10% of you builders find merit in the idea - thats a lot of
good ideas and market potential. So no sermon - just the facts - you be the
judge.
(1) Forget the speed limit stuff. A chute can easily survive 2X any speed the
rv will ever see. BRS and Cirrus are both engaged in adapting a chute to the
SR-20. The current deployment speed limit is 200kts (not mph)! That plane
will gross at 2900 lbs! Sure there is development to do but you are NOT PAYING
for it! I saw the Cirrus mock-up at AOPA, Palm Springs last year and those
folks are serious. Some astute engineering and thought has been given to
load-paths and survivability.
Consider that chute deployment on a top fuel dragster pulls a momentary 12 g's
on a 2050lb vehicle traveling 312 MPH! Of 4,000 passes last year (top fuel
only) I never heard of ONE chute failure! If you add other classes (all
greater than 250 mph) there was probably 6,000 MORE deployments with NO
failures! (data available on request). So forget the materials problem - it
is irrelevant - a parachute can EASILY SURVIVE rv cracking velocities!
Yep, load path, structure, packaging, cg, are all critical but why continue if
you all think it is hopless. It isn't... so more facts later. I'll wrap it
up in the next letter.
Elon (-8wannabe)

REGARDING CHUTE FACT NO.2
The BRS parachute STC'd (yep a real stc folks) for the C-152 has a certified
deployment speed of 145 MPH. The entire package with the fiberglass housing
weighs 42 lbs. It can be made lighter with creative packaging. It is attached
to both of the carry-throughs in such a manner that if deployed most of the
load is through the front carry-through (putting the cg BEHIND) and therefore
pitching up the aircraft at a 70 degree angle. Nice touch - your going down,
tail first - might help dissipate some of the stopping energy! The design and
demonstrated sink rate is 21-24 feet per second. ouch! - your butt is going to
have more colors than my screen saver.
Van has contacted the company in the past and had promised to send reduced
prints to them (but they never got there). Van has stated that due to cg
considerations the unit would have to be mounted forward of the cockpit. BRS
has stated that they plan to follow up with Van. They also indicated that of
all the aircraft requests they get from all over the world - the greatest
amount are from RV owners!.
OK, so there are major problems incorporating it in an RV. But think of it -
this is a real STC and it works. No RV is that far out of the envelope! The
Cirrus design is far more severe than any RV and its going to be certified.
Your not re-inventing the wheel and the majority of the development costs have
been paid by others. Obviously, one RV'r (or the company) can't afford the
costs of a one-off rv design - but the company has indicated that the numbers
don't have to be that large to justify the expense. I don't know the numbers
but I guess with a potential 30,40,50 sales you would get a very responsive
company willing to share costs. What percentage of RV owners is that!
Thanks for listening and sharing - I never thought I would learn so much from
the tube!

To be absolutely certain, check the product for the respiratory protection
requirements. In general, a respirator that covers the lower portion of
your face is used with filters rated for enamel paints, laquers and their
vapors. With the mask on, you should not be able to smell the product.
Beards sometimes interfer with the respirator which then becomes a personal
decision as to how much your respiratory safety is worth to you.

Subject: | Chutes, throttles, et. al (chatter) |
RVers...
I've read all of the posts about ejection seats (I've used one, worked
great, thank you very much!), G-alarms, lefty throttles, and Ballistic
Recovery Systems (BRS). As with most fighter pilots, I have an opinion on
each subject, which I will be happy to share with you. (I hope you're happy
to read them.)
Ejection Seats - great idea, but good luck getting one in a homebuilt. I used
an ACES II, the McDonnell-Douglas brand. It worked great, but talk about heavy
and complex! I doubt you'd even come close to the reliability required in
something which would fit in an RV.
G-alarms - most over-Gs I've seen have occurred during air-to-air combat
missions, either when rolling the aircraft while under G (assymetrical Gs) or
when flying through the other guy's jetwash (wake turbulence). A few years
ago, F-15s were grounded while they were all inspected for broken spars, and
several were found. As others have said, you've GOT to be careful when
rolling and pulling. Going through turbulence will almost always put an
instantaneous G increase on the airframe, depending on how many Gs you were
pulling as you went through it. Your body may just feel a "bump" but I
guarantee the airframe felt every bit of it! Bottom line: if you're pulling
symmetrical Gs, where a G alarm would work most effectively, you'd be just as
well served watching the G meter. I just don't see the alarm being any good
except for telling you, "Hey, hamfist! You just over-G'd this thing!" At that
point, it's too late. The alarm doesn't know that you're about to over-pull,
roll, or go through turbulence.
Lefty throttle(s) - I have over 4,300 hours, about 3,300 of which in military
jets with left throttles and right sticks. The other 1,000 hours is GA
aircraft (C-150s to Beech D-18s) with left yoke, right throttle(s). I prefer
left throttle, right stick, and the left seat for PIC. As Van said in the
RVator, most people find it more "natural" this way; when I asked him about
it this year at Oshkosh, he suggested the right seat option. His concern was
stick/throttle quadrant interference. I asked him if he'd seen Lyle Hefel's -
6 which was one of the best -6s ever built (IMHO) and has a classic 3-control
throttle quadrant (throttle, prop, & mixture), and he hadn't noticed the
configuration. Van has included a sketch of a left throttle quadrant in the
RVator which I saw in the "14 Years of the RVator" so he's aware of it being
done. Bottom line: I like the -6 and the -8. If my wife will live with the
-8, no problem. If she prefers the -6, I'm going with the left throttle.
BRS - I read in the RVator that Van's opinion is there might be three
situations where this might be valuable: trapped in IMC without a way down
and gas dwindling at a great rate; over the mountains with an engine failure;
some structural problem which would still allow deployment of the parachute.
[I'm paraphrasing here...might be wrong on the last one.] Otherwise, he
didn't think it was worth the weight penalty in 1) carrying the system and 2)
beefing up the structure to use it. I would agree with him in this, only
because I think the odds are SO rare that you'd ever need it, it isn't worth
carrying. You probably have a better chance of winning the lottery than you
would of actually needing (much less successfully using) a BRS. Of course, it
would be great to have if you ever did need it. Bottom line: I'm going to do
my best to try to avoid placing myself in a situation where that might be a
player.
Anyone else have an opinion?
Jim

Ok, sorry it took so long to get you guys the information on how to get
hooked up, but here it is.
First of all, I saw some responses comparing it to AirWarrior and a lot of
money to play Confirmed Kill, so let me clear that up.
AirWarrior vs. Confirmed Kill
CK was created to give AirWarrior some competition (well, not just for that
reason :) So out came the Beta version and now you have many people who
haven't played AirWarrior since. (I'm not knocking it, even though it
sounds like it) AirWarrior was fantastic when it came out. Now PC's have a
bit more horsepower and CK addresses some of the issues that couldn't be
done on the slower PC's. For one, you have full screen video instead of the
little view box on AirWarrior. Also, CK runs in resolutions up to 1024x768
(you will only get 640x480 until next week). I've played it in 1024 mode
and it is awesome. (Don't forget, you'll need some horsepower on that
motherboard) Apparently with a 100Mhz Pentium you'll see frame rates of 40
frames per second in 1024x768 screen resolution. That is absolutely phenominal.
Cost?
Someone said something about cost, well, right now it's in a beta state
which means you get to play for free. When the public version is released,
it will cost $2.00 an hour with a 5 hour minimum each month that you play.
Granted that could drain your wallet pretty fast, but think of it in terms
of a fun activity. If anyone wants to go ride a JetSki for an hour it costs
from $30-$40 bucks an hour. Go Watch a Movie and you'll pay $3-7 for
1.5-2.5 hours. So it may cost, but where else can you go get the adrenaline
of a dogfight, get shot down and live to tell about it (while improving your
flight skills). Maybe I'm being a little dramatic, but for now it is
FREE!!! So enjoy it while you can.
How to Get it!!!!!!!
First you will need access to the Internet. You can ftp the file from their
ftp site. ICI2.INFOHWY.COM
Do an anonymous logon and go to the pub/ckfiles directory
>From there you will need to get two files:
CKBASE91.EXE
ART640V1.EXE
CKFAQ.TXT (this file has some good information about the game)
If you have Netscape, just use the following as the location:
ftp://ici2.infohwy.com/pub/ckfiles/
Create a CK directory on your machine, put both the .EXE files in that
directory and run each one. Each will self extract and you now have a
playable game.
A few things to be sure of before trying the game:
Make sure you start your machine with a very basic configuration.
NO EMS NO SMARTDRIVE, JUST A VERY BASIC CONFIG.SYS FILE
ALSO, MAKE SURE YOU HAVE AT LEAST THE FOLLOWING:
A Mouse Driver Loaded
A Sound Card Driver Loaded
A Joystick
Now go into the CK directory on your machine and type:
SetSound
This should bring up a utility to set your sound card
To check out the game without actually going online, just type CK -V1
That is CK then a space and a -V1
If you have a video card that support the S3 chipset 86X or better, you can
play with CK -S0 (the easiest way to find out is to try it, you will get a
message if your machine doesn't have it) It runs about 20% if you have it.
OK, so you've loaded up the sim and are dying to try it.
First you'll want to calibrate your joystick so select the Config button
then press the Calibrate button. The instructions should be self explanatory
PROBLEMS:
If you start the game and the video freaks out, reboot and get to a DOS
prompt, go to the CK directory and type GetVESA
Now try the game again.
If you have any other problems, send me some e-mail and I'll try and help.
I've set up quit a few machines with this sim, so I might be able to help.
I'm also a programmer by trade, so I have a bit of knowledge on the subject.
nuff said, Part 2 will have the section to get online
Good luck (By the way, the file CKFAQ.TXT should have all that information,
but I feel like typing, so you have both instructions)

I have friend, Dave Eby, I flew with in the USAF he has award winning t-18
and c-140 (Best Custom Classic) and has been a crop duster for years and
watch's what he takes in his lungs very carefully. I am told by him and by
some paint companies, that MOST 2 part paints will give off an orderless gas
called isocynates (sp?). He sprays lots of paints for planes, cars, etc and
uses a hood (Wilton makes) that has a plastic window. He uses this with a
vacumn cleaner (blowing in case some Navy types don't understand) with
positive air in the hood. He keeps the source a long way from his painting
and uses a swiming pool hose connected to the hood. There are other more
expensive self contained units, but this gets him by and his products
certainly show it. When I ask a paint company here in Austin about
Vari-prime and what to use on the face, I was told that a cartridge mask
would "probably" be ok, but the gas is orderless and if you had a leak, or
the cartridges went bad, you wouldn'tg know it. The name of the gas is
enough to scare me. I personnally have not started painting yet, but I'm
convinced. It's amazing that most every article I read about painting, no
one says anything and I'm glad Becki passed it on. I yield to experts as I'm
just a dumb retired Fighter Pilot trying to figure out how not make "too

I thought she was talking about veriprime. Does veriprime contain
isocyanates? In the video Bob sprays using a standard cartridge mask.

Last time I played CK, which was a couple of versions ago, you could
*NOT* use a slip connection. You had to log into a text based system
using CK's built in terminal and then use the unix host's telnet command
to enter the CK arena. Has this changed?

Subject: | Flight Sim Instructions PART 2 |
If you don't have a good joystick, you will not like the simulator!!!!!!
more on that later
OK, the first part told you how to get the sim and how to get started, now
I'll talk about playing online.
First a little more babble
This is the scenario, they have this very powerful computer in (Houston, TX)
I believe that contains the world everyone is flying around in. As I said
earlier, up to 500 players can be on at one time. Some of these people are
exceptional simulator pilots. You'll find that probably only 10% of these
people are actually pilots, but don't think you have some big advantage
being a pilot, or even ex-military fighter. You can learn much faster on a
simulator than in a real plane. (you get to learn from your fatal mistakes
and try again) Your initial learning curve on the simulator is far less
than someone who doesn't understand the forces that act on the aircraft, but
many of the people online are absolute aircraft nuts (that don't have a
pilots license??) That may sound very strange, but some of these guys know
tactics inside and out, (Robert Shaw ring a bell?) As a matter'o fact,
you'd swear some of these guys are ex WWII pilots talking about the old
days. I would have never guessed, many of these guys know many of the
advantages and disadvantages of engaging in the different aircraft. (and
they exploit them well!!) Ok, enough.... sorry I keep babling, I'm just
saying, that if you feel this is just a game, you'd be surprised at how
seriously the simulation is taken.
Ok, getting signed up. You must have a Shell account with Telnet access.
Right now AOL or Compuserve doesn't support a dial in shell account (as far
as I know). Ok, assuming you have one.
Start up CK -v1 or CK -s0 and select the configure button again. You will
need to configure your COMM port. So select the port you want to use, IRQ
that is normally used for that port etc.. (if you don't know, you can go to
a DOS prompt and type MSD, a Microsoft diagnostic tool that comes with
Windows, it should tell you all the information you need about your Comm
ports)
Once the ports are configures, select the Terminal button and type ATDT and
the # to your internet provider and press return. Once you have logged on,
type
TELNET ICI2.INFOHWY.COM
You will get a log in prompt that tells you what to do if you don't have an
account yet. Like I said, the accounts are free for now. (who knows how
much longer they'll be free)
Part of the information is a 4 letter ID that will identify you to everyone
flying in the game, so think of a good one. I pick RV6a to identify me (go
figure )
A few other ar 'Pntr' for Black Panther '-bk-' for Black Knight You get
the idea
Once you've entered all the information for your account, you should get a
Main Menu that has an option B that says, Confirmed Kill. Press B and you
will be logged into the system. It should give you a message like,
"Confirmed Kill has logged you IN"
Now Press the Select button and Pick a Country to Fly for. (Red, Green,
Blue, Purple)
If you want to fly with another RVator, select the Gold country.
Each time you make a selection you will see confirmation as to when the
system has accepted your request, sometimes it can take 5-10 seconds to get
a response. For instance after selecting the GOld country, you'll see a
message appear in Yellow that says, "You Have selected Country: Gold" Or
something to that effect.
Now you need to select an airfield to take off from so select field F17, or
F18 (those fields are usually open for the Gold country)
Now select an aircraft to fly with, I suggest starting with the P38, it is
one of the simplest to fly, (No P-Factor correction on takeoff)
Now select the fly button and a few seconds later you will be sitting on a
runway.
When you entered your account information, you had to type in a 4 letter
nickname to identify you in the game, if you press the 'F2' key the other
aircraft flying around you will have their call sign displayed above their
aircraft. Enemy aircraft only show the model of aircraft like 'P-51' or
'P-38' etc.
If no other aircraft are visible around you, press the 'F1' key to toggle a
radar map of the area. press [ and ] to zoom in and out. You will only see
planes within about 10 miles appear on the map. If you don't see anyone you
should either try another airfield or ask on the radio where all the Golds
are.
RADIO???? Yes you have 4 radio channels available. (this part was a little
confusing to me, so don't let it bother you if you don't get it right away
(maybe I'm just slow))
press the / key and a text box should appear at the bottom of the screen. type
.radio 1 103
and press return
This sets radio 1 to channel 103 which happens to be the gold channel
now press the / key again and you should be in the text box again. Just
type a message and hit return. (like, "How do I make this simulator fly!!")
After pressing return you will see you message scroll up in Gold. That
means that your message was received by everyone in the gold country. Each
color represents a different color.
If you are on the runway and want to just get the plane in the air, try
pressing e for turning the engines on, then press the + and - keys for throttle.
If you want to look around, use the arrow keys to look off your left wing,
right wing etc. (you can combine keys too, like the up arrow and left
arrow for a front left quarter view.
JOYSTICKS!!!!
If you don't have a good joystick, you will not like the simulator. In my
opinion the only joysticks worth their salt in a simulator environment are
the Flightstick joysticks. You can get a low end model for about $35 and I
won't tell you how much the expensive ones are.... ($400) I have the $35
one and it works great. The other ones have a bunch of tactical buttons on
them for selecting views and so forth.
If you have a cheap joystick your plane will fly like a duck on drugs. You
will find the plane anywhere from uncontrollable to very difficult to keep
flying and any movement of the joystick translates into random direction
changes of the aircraft.
Really!!!! if you don't have a good joystick, you will not like the
simulator!!!!!!
I've tried quit a few different joystick, and the Thrustmaster line is the
only one I stand behind. They are very precise in the controls. Have you
ever tried to land a plane in a simulator to find you either land a mile
away from the field, or you just crash!! I use to do it all the time. This
joystick made all the difference. I'm to the point now where I can make a
200mph pass down the runway, loop around, drop power, hit full flaps and
drop gear (get real dirty) and still make a good landing. By the way, you
can even make a full stall landing, it kinda neat how slugish things get in
those war birds, hit full power near a stall and flip over on your back!!

Last section of flight sim stuff (Geeze!)
There are several squadrons in Confirmed Kill. I am part of the Squadron
call, "The Flying Pigs" Or the "F'ing Pigs" hehe
Check out our page at:
http://www.tezcat.com/~drmm/pigs.shtml
We have a regular night where we go up and perform a full blown mission with
time tables etc.. Each week someone else puts together a mission where we
break off into different flights, or Tusks as we call them. One group loads
up as bombers while another group as Air to Air support etc.. We fly to
airfields owned by the other countries and take possession of the field. (or
at least we try) We've got some guys who know Robert Shaw tactics like that
back of their hand. Some real talent for this kinda stuff. Anyway, if you
decide to give it a try, I've already annouced to the other Pigs that we
might get some company from some friends of mine (at least I'd like to think
of you RV builders as friends). They know you're all pilots and having a
great time building RV's. So if you get on line and figure out how to use
the radio, just ask if there are any Flying pigs online and tell them that
RV6a sent ya. They'll help you out if you need some. And if you get
hooked, we're looking for a couple more good squad members. As soon as this
goes public, there will be real campaigns, LIke the Solomon islands etc..
It's really fun being part of a squad, getting a consistant wing man etc..
at least a few pigs on. I think our numbers ar 18 by now.
Hope to see you on. If you want to get together online, let me know by
E-Mail, I'll be on tonight from about 1700PST to 1900PST

I absolutely agree with Ross on this point. You do not want to touch the
actual spar flange (the 1/4" thick aluminum bars) which make up the
main strength members of the spar. But we don't have to. We are talking
about something else altogether.
There are two spar *webs* made of .040 which have flanges on them to which
the tank is attached using nutplates. The flange of the forward spar
*web* is what sometimes interferes with the tank baffle rivets. It is
this spar *web* flange that I suggested filing to clear the rivets, not
the main spar flange.
Sorry if I caused any confusion. Damaging the main spar flanges is my
worst nightmare. I couldn't really see any solution other than building
completly new wings if that happened. (knock wood)

I think the part that was referred to earlier is the row of #8 screws
closest to the trailing edge of the tank skin. The screws can't run all the
way to the root of the wing because of the spar flange. I'm surprised
someone actually notched out the spar flange without quiestioning that
decision.
As I drilled those holes, I almost forgot about the spar flange!! what a
mistake that would have been. I think I may have a problem though, when I
drilled the root most #8 hole, I think the drill went through and made
contact with the a 1/4" spar flange. (I'll double check when I get back out
to the hangar) Does this mean I am gonna have to rebuilt my spar if I put 1
ding on the spar flange? If it's just a ding, can I make sure the mark is
smooth and primered? Obviously no dings are best, but could 1 or 2 nicks be
filed out and painted?
I hope so, I'm gonna want to shoot myself if the spar needs to be rebuilt!!!!

I'm surprised if you actually dinged one of the spar flanges. I found
there was plenty of clearance (well, maybe 1/8") when I drilled the #8
holes. If the hole is actually overlapping a spar flange, you may have
difficulty getting a nutplate in there. As far as the structural
implications of nicking the flange, talk to Van's. If its only a nick, I
think there would be a good chance you could dress it out, assuming you
can get the tools in there.
For those who havn't drilled these nutplate holes (for the dimpled
nutplates, aft of the spar) by all means use a drill stop set so the
drill just barely pokes through. That should reduce the pucker factor.

I've been told that there is NO cartridge that will reliably filter out the
Isocyanates found in urethane aircraft paint. That said, I can say that I
used that type of respirator with a Combination Cartridge, GMC-M (two each).
On the side of the cartridge it says "for respiratory protection in
atmospheres containing less than 0.1 percent organic vapors, 10 ppm Cl2, 50
ppm HCL or SO2, and 30 ppm HCHO by volume and against dusts, fumes, mists,
asbestos--containing dusts and mists and radionuclides".
This respirator was the best I could find and I used it when I painted the
interior of my RV-6 with urethane paint. I couldn't smell any paint fumes
while painting. However, shortly after painting I had a raging headache.
There is no cartridge that will filter out isocynates. What you can't smell
CAN kill you.
Don't make the mistake I made. Use a fresh air source and also cover all of
your body. The paint can enter your body by absorption thru the skin.
If cost is a factor I have heard of someone using a grocery bag with a
plastic view window cut into it; the air source was the blowing end of their
house vacuum. Don't know if I recommend this but it may give you ideas.

3. Wipe entire area with 3812S or 3832S (Enamel Reducer)
4. Mix one part 615S with one part 616S COnverter or one part
620S Fast COnverter. Mixture is ready to spray
5. Spray 2 coats at 30-45 pounds allowing 5 minutes flash between coats.
In reality, I clean with MEK, scuff the surface lightly with scotchbrite,
then spray one coat. Instead of cleaning with MEK, you can use a
phosphoric acid (AKA Alumiprep, PPG DX533, DuPont 225S), but since
Veriprime is a self-etching primer, it is not necessary.

Unless the paint is the type you slop onto your house with a brush, it
contains chemicals in its fumes that are hazardous to your health. Visit
your local automitive paint supply house, and ask them to recommend a
good respirator. It will typically have a pair of removable charcoal
filters. These filters are good for about 10 hours after being exposed
to the air, so plan on using a freash set for each paint session.
This type of respirator, however, is not sufficiently effective when
spraying paints that contain isocyanates (Do you recognize the similarity
between 'isocyanate' and 'cyanide'?) Almost all polyurethanes (like
Imron) contain isocyanates. A lethal dose of isocyanate can be absorbed
thru the skin! When spraying this kind of paint, Disposable protective
clothing, gloves, and a full-face supplied-air respirator should be used.
You may think that you are safe by using spray cans. think again. I
recently had a spray can explode in my hand. (lab analysis revealed a
defective seam) Had I not been wearing safety goggles,
I would be blind in one eye.

No, Veriprime does not contain isocyanate. If a paint contains
isocyanate, it will say so on the label. As a general rule, it is the
polyurethane paints that contain isocyanate. Normal acrylic enamels and

Gentlemen:
As RV builders and pilots we all have a responsibility to ourselves, our
families and our fellow pilots. Here are my thoughts as a fairly low-time
pilot (320 hours, SEL, MEL,Instrument) with 42 hours in my RV-6 and a
surgeon.
1. Build the darm airplanes as per specs---don't change anything espec.
in the structural areas. The designs are solid and well engineered.Fly them
within their gross weights and proper speeds.
2. RV's are not designed or built for serious, competative
acrobatics(and I don't just mean airshows!) There is absolutely no need to
pull negative G's or more than 3-4 positive G's in any manuever you should be
doing in these aircraft! All the discussions about G-warnings, ejection seats
and ballistic parachutes should really not apply since you are getting into a
realm of flight testing that has more to do with luck and circumstance than
knowlege and skill. If you want to be more macho, get yourself an Extra,
Sukhoi, Pitts,etc.
3. Learn how to fly the damn machine!---from somebody that really
knows! Even if you are a high-time hot shot stick-pusher, these airplanes can
teach you a great deal--we can always learn something to make us better and
safer pilots.
4.GLOC can be instant and fatal espec. in weekend pilots that are not
in shape and not in constant training.If you don't beleive, ask the experts!
There are many good articles covering this topic that have appeared in Sport
Aerobatics----Read them!
5.Steve Mosely was a good friend and a very unique and talented man.
Let's learn from this tragedy hopefully to prevent some future accident.

This is all my opinion, and you should check with your paint
supplier instead of listening to me anyway. Read the product
literature and MSD! Never take a paint product into your shop
until you read the label and understand how to store it and
what to do if there is a spill.
---------------------------------------------------------------
Vari-prime is not a Isocynide based primer. One of its biggest
advantages is that its not nearly as big a hazard. Its not the
best Primer, but it has a good balance of safety, cost, ease of
use and protection. I think this is why Van recommends it, its
good enough protection and it won't kill his customers.
Most don't use a mask at all with primers like Vari-prime
because you can get away with it, unlike paint with Isocynates
(excuse my spelling here) which will make you sick with
certainty. In case you have not had the pleasure, its like a
Flu that lasts 1 to 2 days, your hack up junk from your lungs,
puke, feel weak, headache, etc. After the fever breaks, you
are weak for 3 or 4 days. Each time it takes less and less of
an exposure to trigger this reaction. You can also get this
from some Resin systems (Epoxy).
A good ($35 +/-) respirator with charcoal cartridges (They are
marked for use with paints and Lacquers) is plenty good enough
for etching primers like Vari-prime. You need something that
can filter out the paint particles and mists, which a
respirator can do reliably as when its full it is also plugged
up and you can;t use it any more.
The Cyanide gas given off by catalyzed paints like Imron and
urethane based primers can't be filtered, only absorbed by the
charcoal in the cartridge. The problem here is that you never
know when the charcoal is full... So you are protected for
awhile and then with out warning your are not. A full face
mask with positive fresh air flow is the only way to know for
sure. You should always store your mask and cartridges in an
airtight bag so the charcoal does not get filled up while not
in use.
There is a way around this, but I won't share it here.
With regular Zinc Chromate primers: these are usually a Lacquer
based paint with chromate added. They are no more a hazard
than Vari-prime in the wet state. good ventilationventalation
or a respirator with charcoal cartridges are ok. The Danger
comes after its dry, the dust and chips are toxic both to
ingest or to breath the dust. This becomes a problem if you
need to sand something; use water and don;t let the dust get
all over the place. (don't get over protective here, a little
bit here and there is not a big deal, a layer over everything
in the shop and the floor is.)
I am trying to put all this sage wisdom into a single file, and

Subject: | MOre info on Steve Mosley's crash |
I talked to Andy Hanna yesterday at Copperstate concerning Steve Mosley's
RV-3 crash. Andy said the point of failure was NOT the attachment point
at the root of the rear spar. The point of failure was the main spar
about a foot out from the root. This information coincides with what
Bill Benedict told me at dinner last night. He says that last december
they stress-tested a spar and took it all the way to failure. It failed
at 8.9 Gs, in the wing-walk area. The flange strips buckled aftward. He
went on to explain that one of the purposes of the xtra ribs in the
wing-walk area is to reinforce the spar flange strips at this point.
I hope I've paraphrased Bill correctly. There was half a table's worth
of noisy people between us.

We have been using fuel lube on the gaskets with good results. The fuel cap will
be the leak point on pressure testing. I used the balloon method to test the
tank and had a hard time getting the cap to seal. Perhaps a vacuum bottle cap of
the right size would work.
Good luck

Subject: | Re: Pressure Testing Tanks, other mods |
I would put some sort of sealer on these gaskets. I have done several sets of
tanks, all with no leaks. The last set I used tha cork gaskets, but I won't
be doing that again. My methods involve using pro-seal type sealer on
everything, esp. the screws that retain the sender and the access cover. My
worries on this set of tanks with the cork gaskets is: I don't feel the cork
will last as long as the sealer, and is the sealer I used on the screws going
to hold? I used Form-a gasket on the screws. During the test for leaks, the
screws were the only thing that leaked! I replaced them with the cad-plated
ones that came with the kit, and stopped the leaks that way. 20 hrs as of
today, and no leaks yet.
I have some mods to construction on the -4 fuse, such as butt-joints on the
fwd side skins, (much smoother), and an easier method of putting those
blasted nutplates along the top longeron on the -4, also eliminating the
funky lap joint at the boot cowl skin, where it meets the side skin. Anyone
interested?

I suspect the problem you are having is due to the way AOL processes email
headers. In the messages that are sent out from the rv-list, there are
two "from" addresses. The first one looks something like this:
From owner-rv-list(at)matronics.com Sun Oct 15 09:23:24 1995
The other looks something like this:
From: dralle(at)matronics.com (Matt G. Dralle)
Notice the ":" in the second line. Mailers (the delivery software, not
the program you use to actually read your mail) will use the "From" address
to return errors and other messages about delivery problems. Having this
set to "owner-rv-list(at)matronics.com" means that only I get to read all that
garbage and posters to the List don't have to know about it. The second
"From:" (note the ":") will always have the *actual poster's email address*.
This second From address is the line that mail readers are suppose to use
when listing mailbox contents. Obviously, AOL is using the "From" line
and not the "From:" line when creating a directory of email. All of you
on AOL and any other Email Service Provider should contact your technical
support and complain about this behavior.
Hope this clears things up a bit.

With reference to your words regarding throttle, etc. on the left side, I
intend to gang two sets of throttles (+etc.), one set on the left side
and one set in the middle. I'm a left throttle flyer (stick in my right
hand) with more than a few hours in single seat jet fighters as well as
helicopters. Originally, helicopters were designed with the collective
lever in position for the left hand. As a result, the pilot sat in the
right seat. When dual flight controls were eventually fitted, the
co-pilot sat in the left seat and a second collective lever was added to
the left side of the left seat. Us right stick, left throttle guys have

I seem to recall someone posting a good idea for sealing fuel caps on
this list a while back. The idea was to take a large round balloon, cut
the neck off
and stretch the rubber over the tank side of the cap, then insert the
cap. This seals the hole in the middle, which is probably where the
leakage is happening. When I pressure tested my first tank I didn't do
this, and my "pressure regulator" balloon slowly leaked down over a day
or two. I plan to retest with a sealed gas cap and keep my fingers
crossed.

If you say 3-4 G's is fine, then these discussions are completely valid.
Remember the mention of 3-4G turbulence. Probably no need for me to add the
4 G manuever to the 4 G turbulence. ..but I'll do it anyway 4+4 =8-G's

To be more macho? If I was trying to be macho, I'd buy an Extra, Sukhoi,

Don't get me wrong, I love my RV! (But I bet most of you married men find
some of those super-models extremely appealing, but probably love your wife
and wouldn't have it any other way) Not to mention the cost of having a
super-model.... I mean Extra, Sukhoi, Pitts. Anyway, the point being,
an RV is an absolute joy to fly and some people like to take their sports
car to the limits, and accept (or ignore) the risks associated with that
preference.

Yup! And the more you push the flight envelope, the more there is to learn.
Actually, there is equally as much to learn beyond the flight envelope.
Unfortunately, pushing the limits of anything can be dangerous. I remember

No arguments here, it's just another one of those accepted risks. You jump
from a plane and you accept the risk that the ground is rushing towards you
very quickly, you just rely on the chute to slow your butt down, just as you
rely on your skill, physiology and experience to keep you conscious. (using
the skill to keep the aircraft from pulling more that you should)
> 5.Steve Mosely was a good friend and a very unique and talented man.

Unfortunately, at this point, the information leading to the crash is
limited, so there isn't much to learn except for the basic philosophy. As
you said earlier, no matter how talented a person is, there is always
something to learn. And no matter how talented you think you are, it can
happen to the best of us. It is sad and I can't begin to understand the
pain Steve's family must be going through, but I really do feel for them in
my heart. Something we must never forget, flying was not something our
bodies were meant to do naturally, unfortunately, that also means dying
might not come naturally either.

Thanks all for clearing up the distinction between the requirements for

I remember one day I was cleaning my gun with the 620s accelerator and
since it was just a quick squirt, I didn't put my mask on. Believe me,
you will smell the acid component of Variprime quite distincly. In fact,
without my mask it damned near knocked me off my feet <1/2g>.

Hello RVers,
My name is Jerry Forrest. I am a molecular biologist by trade and have been in
basic research for 25 years. I have enjoyed flying and instructing in gliders
for almost 18 years. Last year I added a private SEL airplane rating to my
license. My knowledge of building airplanes is very limited so I have been
reading the posts on this list for several months and I have learned a
tremendous amount from your discussions. I am in the process of acquiring tools
for building and have received the RV-6 empennage kit. I look forward to the
challenge of building and learning from all of you.
Variprime- Armed with all the information that has been posted over the last
couple of weeks on variprime, I purchased my first quart of variprime and
received the following information from the dealer.
Variprime does not contain isocynates.
Variprime is a two component self-etching primer. The variprime itself is
called #625S(primer). It is mixed with a converter (1:1) which is #616S. When
both are mixed together it becomes the self-etching primer. The
converter(#616S) is mostly phosphoric acid and is what gives the primer its
etching or griping properties. The converter is not a catalyst; therefore, it
is not comparable to other primers that use a catalyst and require a positive-
pressure respirator. However, this does *not* mean that precautions can be
loose. The following is taken from the warning label.
Repeated and prolonged overexposure to solvents may lead to permanent brain and
nervious system damage. Eye watering, headaches, nausea, dizziness, and loss of
coordination are signs that the solvent levels are too high. Do not breathe
vapor or spray mist. Do not get on skin.
WEAR A PROPERLY FITTED VAPOR/PARTICULATE RESPIRATOR approved by NIOSH/MSHA for
use with paints (TC-23C), eye protection, gloves, and protective clothing during
application and until all vapor and spray mist are exhausted.
The respirator that is recommended is a cartridge respirator. However, if the
spraying is done in an enclosed space or in situations where continuous spray
operations are typical, or if proper respirator fit is not possible, a positive-
pressure (TC-19C) respirator is recommended.
Hope this helps

Between pounding rivets, thought I would put my two cents in. As an ex AF
Fighter type, thought I would explain a "flameout" pattern--and of course
dating myself to what I flew, the T-33, F-86, F-101, F-102, F-104, and F-4.
The only birds that were capable of a flame out landing was the T-33, 86,
102, and 104. The other machines had two engines and if you lost them both,
you had no hydraulic/electrical system to operate. The 102 and 104 had a RAT
(Ram Air Turbine) that you dropped in the breeze and it generated enough to
get you down.
The flame out pattern is a 360 degree overhead pattern and has a high key low
key (after 180 degree of turn), base key and final approach. The high key
was dependent on the bird. I.E. a T-33 was 5,500 feet and F-104 15,000
feet!!! IF you hit high key or low key at the optimum altitude, you could
make it. The 104 killed a few folks as you were coming down the chute at
220KIAS, take off flaps, and no gear and you held the gear to the flare. As
the shuttle does, you had to time your flare for the gear as you lost all
your speed in a hurry when you dropped the gear. The shuttle of course has
all computer type approachs and they are canned. I don't by any means imply
that there isn't great skill involved, it just isn't the same method. Now
feature coming down at X feet per second nose down, and then deciding you
were not going to make the runway. YOU must eject at a high enough altitude
for the ejection seat to overcome the sink rate. I understand the F-16 has a
high key of about 6,000 and have watched them practice flame out patterns and
they have a lot of airspeed and altitude to play with. BUT, anytime they
don't have the right numbers, that is what the ejection seat is for. I
personally have only dead sticked one bird and all the numbers were perfect.
If not--bye a/c.
sorry for the long "words", just thought some would like to know.

I doubt you could get cork gaskets to seal "dry" (without fuel-lube or
similar).
If you use cork/fuel lube for a temporary seal plan on prosealing for
the final seal, you won't want to use the same ones if they've been
contaminated with fuel lube. Fiber gasket material from an auto parts
store might be an alternative -- you can get it by the sheet pretty
cheaply and cut out a bunch of gaskets.
I had a tough time sealing the access plates temporarily for pressure
testing. Mostly they leaked around the screws. I later found some fiber
washers for #8 screws -- with a little fuel lube underneath these
washers should help seal them up. Also a friend used buna-N gaskets and
fuel-lube (and the fiber washers). It held for the pressure test. He
plans on just leaving it that way for the final seal.

Reply to: Dead Stick Landings
Good point about the destructive force being 8X greater at 140kts than at
50kts - same reason twins have a poor survival rate - they land too fast!
However, the military fighter is most to likely suffer structural failures?
due to things like, 50 caliber's, sam's, flack, heat-sinkers, etc. It is
considered good form to exit upstairs. The EARLY ejection seats would not
allow zero altitude survival. However, the Martin-Baker seats (in the 60's,
my last data point) would allow zero altitude at 90kts ejection with
survivability. I think today they allow zero/zero (i.e.,altitude/speed).
Your point is well taken but it was the LAST part of the ejection envelope to
be developed (25 years later!). The first and primary need was to get out at
altitude - it was assumed there would be no stick left, dead or alive.

Ok, opinion mode on ...
Have to disagree with the ejection seat reasoning - my impression
was that it was there primarily to get the hell out when someone
put a sidewinder up your tail - the dead stick feature is secondary.
Not too many fighter pilots would think about bailing on an aircraft
that may end up in someone's yard/pool/garage/bedroom just because
of a slight lack of thrust. Even saw an amazing HUD camera video of
an F16 driver who lost his engine over a major city (Chicago maybe?),
found an airport (he was ifr at the time), and put the bird down on the
centerline of the runway. Damned impressive.
Also, I'd hope that a forced approach (esp. in an RV) would not HAVE
to result in a pile of scrap. At least they convinced me that it could be
done during my flight training (hmm... maybe I've been led astray?).

The real reason that military jets have ejections seats is that
you cannot survive a "dead stick" landing in a machine that stalls at
145 KIAS. Just run the numbers through E=1/2m(VxV) and you'll rapidly
come to the conclusion that it can't be done. You can dead stick a RV
with a high degree of success (you live, airplane is scrap).

The point of the equation is that the energy dissipated in an
*off-runway* landing goes as the velocity squared. i.e. double the
velocity means 4 times the energy to be dissipated by you and the airframe.
I you have a long enough runway the (like the space shuttle), there is
no issue...

One of my complaints is knowing about all of the options before buying
the kits. I would have ordered the .020 elev/rudder skins if I had known
about them. When I ordered the kit, I personally was at Vans Aircraft
manufacturing facility in North Plains Oregon. And I still could not get

rebuild or build new elev/rudders with the .020 skins (frustration!).
I have the wingkit now and I did not know about the single skin option,
but I don't want it. Now before I order the fuselage, is there any of
these hidden options that I should know about?

Firewall recess. They sell both a pre-cut that you bend and rivet
yourself, and a pre-made one that's all pre-bent and spot-welded, just
cut a hole in the firewall and put it in there.
Also order the spring trim kit now I think if you're going that way.
Other than that are the ones you probably know about:

Chris,
... the key words here are "the gear legs are pre-drilled to
their mounts". Since the mounts are attached to the front surface of the
spar, and the gear legs are pre-drilled, no rotation of the gear leg is
possible (and hence toe-in, toe-out), so the wheels will point the way they
are going to point!
As long as Vans has a good jig for holding everything to-gether
while that 5/16 (or is it 3/8?) hole is drilled into the _hardened_ gear
leg, then the wheels will point in the right direction. Given the horror
stories of drilling the legs in your garage (#2 after Proseal!), and the
accuracy losses possible in this home process, I for one am glad I got mine
pre-drilled.
Even George O. in his video makes it look easy, but then he shows
you the final product and tells you how many drill bits he broke. Full
marks for honesty George :^)
One word of caution though, thoroughly de-burr this bolt hole in
both the gear leg and the gear mount before assembling the parts. The fit
is so tight, that any small burrs will gall the metal, and jam the parts.
One of the 1 inch diam., 1 inch long, ScotchBrite wheels in your die
grinder is excellent for getting inside the gear mount tube, as well as
doing the gear leg hole on it's curved surface.
... hope that helps ...

Energy equals one half the mass time the velocity squared. Yes,
you cold dive it at the runway, if there was a runway. However, you
almost never have a 8000 ft runway when you need one. The Space
shuttle was designed to glide to landing and computer profiles put the
gliding shuttle in a position to land. Modern fighters have a glide
ratio just above that of a crowbar. When I was flying the T-38, I
would much rather give the problem to the taxpayer rather than trying
to find a place to crash and kill myself.

Whether you have a missle up your whistle or no whistle at all, a
military jet capable of supersonic flight is a piece of junk when it
won't fly. Just because some irresponsible fool attempts to "dead
stick" and survives is no ticket to a medal. As a commander I would
severly censer anyone who would even attempt such a maneuver. I,ve
had experience with the T-38 glider and I,m not at all impressed with
handling characteristics. I got two relit and when home. As far as
pointing the junk away from people, most think it's a good idea.
Personally I have a primordial urge to find an elementary school.
You should have no problem making an evergency landing in Your RV
in you neighbor's corn field. The engine out front will punch a hole
in most soft and forgiving brush. A jet engine behind you has a
tendency to act as a suppository.

If you get the pre-welded one, make the firewall fit it, since they are all
(at least the present batch) 3/64 inch too wide. They are well made, and
it's a pain to bend the flat one neatly in your garage.

the wings, claimed copious amounts of air, even on the ground. I wonder
if anyone besides me thought this a great idea. I've purchased two vent
kits, and plan to put one in each wing, one for front and one for back
seat. (No, I'm not building a four-seat -6!!!) Before I cut aluminum I
thought I would see if anyone has any further thoughts on the matter, and
maybe the original poster would have any more info on the process. Thanks
in advance guys, and gals...

I called Du-Pont's tech-support and was told that 60 deg. F. was the
coldest that you would want to spray the product. Last January, I
was ready to prime all of my fuse skins ( a whole lot of surface
area), I waited for the warmest day possible ( about 50 deg.) , put
the Vari-Prime and skins in the house to get them to about 70 deg.,
put a heater on the air compressor's tank( to get the air hot) and
sprayed in the sun. This worked very well.

Just my opinion, but I would not want to cut any extra holes in in the bottom
of my wings especially at the root end of the wing which carries the most
load.
On the other hand I have seen some really neat air inlets in the leading edge
of the wing root fillets of the RV-4 that are really supposed to work well.

Cheryl suggested a G-meter with an audio alarm. It looks like the wheel has
already been invented. Page 254 of the 1995-1996 Aircraft Spruce catalog:
"The "G" Spot Accelerometer is not only much lighter than conventional,
mechanical models, but its micro-computer controlled solid state
construction enables it to be more accurate, sensitive, and durable.
Measure loads to +15G to -10G, features 22 memory locations, programmable
visual and audio alarms, measures system voltage and alternator
performance, is back-lit and is completely solid state. Mounts in
standard 2-1/4" instrument hole. Made in U.S.A. $329.95"
This is only about a hundred bucks more than a conventional 2-1/4"
mechanical G meter.

Hi Bob,
My question is why are you sure you want the .020 skins on your plane?
I am not trying to make a point. I am interested in information.
My current understanding is that for the design speeds of the RV-6
the thinner skins (.016 I think) are completely sufficient. Also,
if there is going to be a balance problem with the RV-6, I think it
will tend to be tail heavy, which means that putting extra weight as
far to the rear as possible might not be a good idea.
If there is some overriding reason for wanting the .020, please let me
know.

Bill Costello

I hate to welcome you back by taking exception to your statement, but I have
to disagree about them being built better by so called professionals I can
name a couple shops in my area that I would not want to build my airplane and
they are called professionals. I think that a owner builder tends to take
more pride in their work. Yes there are exceptions and some shops do a good
job. I doubt that a comparison has been done that will prove that so called
professional built airplanes are safer than homebuilt airplanes. Myself I
don't have a problem with someone paying to have a airplane built but that
would sure take alot of the fun of flying it away for me. I also realize that
some people don't have the time to build so the next best thing is to buy or
pay to have it built. BUT IT IS not a safer airplane.:-)

I'm the one putting this mod on the list. I mounted the scoop outboard of the
wing walk, 3" aft of the skin joint line. Use a 2" wide doubler, riveted to
the bottom skin outside of the scoop flange line, so no rivets hold the scoop
up from a tight fit against the doubler. Simply use RTV to install the scoop
itself. I used only one scoop on the last a/c, and it feeds both front and
back, with plenty of air. I also put a shut-off valve, like a throttle plate,
in the inlet hose, and was able to connect the heat hose to the front of the
system. POOF! Heat and vent air in the same system. I have noted one
problem-- the hose that passes OVER the ail pushrod should be 2 1/2" dia. in
this area only, due to the fact that it has to be smashed somewhat for
clearance between the tube and the floor. The 2" hose, when smashed enough,
restricts flow a bit. It would also help to run the floor stiffeners fore/aft
instead of side to side, to allow for the hose.

Also BAC has a firewall kit. I don't know if Van's has it yet or not.
Call them or Stve and Theresa at BAC (916) 676-5601. Don't get this
kit if you enjoy assembling jigsaw puzzles with no directions. Franks
instructions are a must if you do the firewall yourself. The only
drawback I can see with the firewall kit, other than the pure pleasure
of doing it yourself, is that you will not be able to fit the bottom of
the firewall to the exact dimensions of your bellypan. There is enough
variation in the bellypans that this area may not fit exactly.

Subject: | Wing skinning questions |
I finished aligning all of the rib flanges on my leading edge
ribs last night and decided to place the leading edge skin on
just to take a look at it. As soon as I did this, I realized
that I had a lot of questions about the alignment of the skins.
I looked through the plans and read both Van's and Frank's
manuals, but still have questions.
1) Regarding the leading edge skin: Van says to overhang the
outboard rib by 1/2 inch, Frank says 5/8 inch. I moved my
outboard rib in 1/8 inch so I can see where Frank's number
came from. The question I have is what is the desired
alignment with the most inboard rib (the one without the
corresponding main rib)? The plans seem to show that the
skin edge should be flush with the rib.
2) Regarding the tank skin: The tank skin is 48 inches long.
On my wing, the distance from the most inboard leading
edge rib to the inboard edge of the spar web that mounts
the tank is just under 49 inches. This means that the
inboard edge of the tank skin will be about 1 inch
further from the fuselage than the root edge of the most
inboard main rib. Is this normal?
3) Regarding the top skin: I have the one piece top skin and
would like to know what the minimum overhang over the most
inboard main rib needs to be. If this leaves me with less
than 1/2 inch overlap on the tip rib, I'm in trouble!
Assuming it is long enough, I plan to line it up with the
leading edge skin at the tip and leave any additional
overhang at the root until I mount the wings to the fuselage.
Am I walking into a trap here?
4) Regarding the bottom skins: I'm confused about how the
overlap between the skins is done. From earlier posts, I
believe the outboard skin goes under the inboard skin. If
I remember correctly, the plans show two rows of rivits
where the skins overlap. One of these rows must go through
the rib at the overlap, I'm not sure where the other one
goes. Which drawing is correct?
<----- outboard (tip) inboard (root) ---->
| <-- rib where skins overlap
|
___|
_________________________

- OR -
<----- outboard (tip) inboard (root) ---->

|
___|
____________________________
outboard skin ^ ________________________________
^ ^ inboard skin ^
rivits
5) Regarding the bottom skins: What is the minimum overhang over
the root rib for the bottom skin? What is the minimum overlap
between the skins?
6) Finally: Is this all detailed on the plans and I'm just not
seeing it? If so, could you please reference the plan sheet
number?
As always, thanks for the help.

I guess I didn't phrase that properly. I meant that the airplane would be
better built than if the person that was having it built had done the work. We
had one Wheeler Express that the work was so bad, if the owner had finished it
himself, It would probably have come apart on the first flight. I have seen
some Glasairs that were built by private individuals that were far better than
most professional planes I've seen. I also agree that there are some shops out
there doing pretty bad work (having been a part of 2 rebuilds of so-called
professionally built aircraft, I can speak from experience). My main point was
that some poeple just have problems building and if they went ahead and
completed the aircraft, it would have been unsafe to fly, so they came to us
and the local FAA guy takes this under consideration.

Subject: | Questions on exterior primer & painting |
I am close to painting my RV-4 exterior.
All the inside parts were cleaned, etched, alodined, and primed with
Randolph Epibond two part epoxy.
The cockpit was the same and then topcoated with Imron (Duponts poly epoxy).
I liked the way the Imron when on and looks so I will probably do the
exterior in Imron or one of the other brands of polyurathane (PPG or ?).
I plan to clean (with alkiline soap) and scuf with red Scotch bright pads
and then etch and alodine. Cleaning with soap is per Bob Brashier who
claims this gets the fish oil off. Other have recommend the same.
My questions have to do with what primer to use.
I prefer a non sanding primer on the metal as I don't like the idea of
having to sand all the skins if I don't have to.
Dupont says you can use either Colar epoxy 2 part primer (the one they prefer)
or Variprime (self etching). From what I have read, the Variprime
is a non-sanding primer and can go on fairly thin.
The Corlar, they recommend a light sanding and it can coat 0.7 to 1.5 mil
thickness. I like this one because it is a light gray color and is
recommended under light paint colors.
Does anyone have any ACTUAL experience with either of these primers or have
any recommendations on other primer/topcoat's like PPG or Sherwin Williams,
etc.? Any experience with 'wash primers'?
I have not decided on the sprayer. I have a standard suction gun and cup
but will research the HVLP guns (not the Croix turbine type).
P.S. Don't send me mail about the hazards of using the Poly paints.
I am aware of the issues and plan proper protection and a well ventelated
paint booth. I built a rack full of 19/25 inch filters 8ft high and
am using a 36inch attic fan to exhaust the fumes (at floor level so
it will pull the overspray down).

I'm going to get into trouble with this answer but here goes. I
bought the RV-6 becasue it is a good compromise between an all out
hotrod and a plane that you can actually take another person and go
somewhere. But what I want to do is some aerobatics within the design
specifications of the airplane. Every time I talk to someone about
aerobatics in an RV-6, I get an answer like, with those thin skins it
wouldn't be a could idea to do whatever it was I wanted to do. What I
want to do is hammerheads, tailslides and a full rolling torque roll with
a tailslide. Now I know that .020 skins will not allow me do this in an
RV-6, but for added safety for the possible RV-6 aerobatic maneuvers, I
feel it would help. I plan on doing the type of aerobatics that you see
Van doing in his airshows. If all I was going to do was cross country and
an occasional loop or roll, I would not hesitate to stay with the thin skins.
As far as weight and balence, the skins will be heavier, but if I
go to a constant speed prop it should balence ok. I think that if you
want to do a lot of aerobatics in an RV it is a real good idea to have a
constant speed prop to slow you down. Even the RV-6 goes real fast in
the downhill mode. Also in the event I get serious I will screw my
wingtips on rather than riveting so that I can take them off and put a
flat plate on much like a Mooney's wingtips. Supposedly this will give
me more drag (which is good) and increase the roll rate, reduce wing
span, increse sink rate and who knows what else.
I'm probably way over my head in this area, but any comments from
the experts will be appreciated.

The point of the equation is that the energy dissipated in an
*off-runway* landing goes as the velocity squared. i.e. double the
velocity means 4 times the energy to be dissipated by you and the airframe.
I you have a long enough runway the (like the space shuttle), there is

People do scratch-build from the plans, but they are primarily intended
for kit-builders. The "preview plans" are a reduced size set that Van's
sells for $50 with the manual. Due to the size reduction you can't read
some of the dimensions so it really wouldn't be possible to build from
them. At any rate, you cannot legally scratch-build without purchasing
your own set of full size plans and getting a builder number. That's
good for ONE airplane, either scratch or kit.

You can blame me for no rudder instructions. When I started building,
Frank's manual started with the elevators. I promised to help him add
some of the missing sections, so I wrote the section on the horizontal
stab. I fully intended to write the rest of the missing sections, but
life interfered.
Actually, what would be nice is for someone who has just completed the
rudder to step up and write that section for Frank.

These are two different things: preview plans and the 'real' plans.
The preview plans are greatly reduced in size and are intended for
just that -- preview. That is, to get a feeling for the construction
and to study in between building -- like on the train to work, etc.
Van has all sorts of disclaimers and warnings that the preview plans
should NOT be used for construction. So, if he has his way they
will not be used for any kind of construction at all.
Hope this helps.

Ok I seem to be a bit confused here, I saw a set of plans selling for
about $225 called preview plans, this was what I was wondering about.
I'd now assume that these are the full size plans, and not the reduced
size plans.

Subject: | Elev/rudder thin vs thick (tail slides!) |
Bob, adding the thicker .020 skins is probably a good idea if
you will be doing aerobatics. The .016 skins have cracked on a number
of RV's, maybe even without acro.
Hammers are not hard on the airplane as it is just a pullup and then
set and relax till you run out of speed and then rudder it around.
This may put a little strain on the rudder but I would think it is
not very hard on the AC.
I do question your wanting to do tail slides and torque rolls in the
RV. When sliding backwards and the heavy end decides to point down,
it snaps very fast. This is probably hard on the motor mount attach
point. There is some stress on the tail when you apply the stick
to force the wheels up or wheels down turn around.
Also, as you are falling backwards in the tail slide, the controls
are now reversed as air is trying to flow over them from the rear.
This can snap the controls to full stop if you let the stick or rudder
get away from you. It has been known to break controls.
I don't really thing a RV is a tail slid/torque roll type of aircraft.
But, you built it and you can do what you want with it.
I have done tail slides in my Pitts just for grins and it is fun.
I think it is better built to take this abuse.
BTW, when you do the tail slides, be prepared for the engine to stop.
When you fly backwards, the air wants to make the prop turn the other way
and it can stop the engine. It did this to me on my first tail slide.
I don't have a starter. It took quite a bit of altitude to get the
prop going again. I was glad I started a little high and was close
to the airport. I have read of several other pilots that have had
the same thing happen.

I assume that you are building an RV-4, or have an older RV-6 wing kit

The row of pre-punched holes in my leading edge skins is 5/16-inch
from the edge of the skin in this area. Therefore your assumption
is correct: The skin edge should be flush with the rib.

Yes. For an RV-6, look carefully at sheet 10 of the plans and you'll see
that.

The inboard ends of my main skins are even with the inboard edge of the
rib flange. With the pre-punched skins, I have about 1/2 to 5/8 inch of
overhang at the tip.

Um, if you try to trim the skin after it is riveted down, you will have
an extremely difficult time doing so without scoring the flange of the
spar.

The outboard skin now overlapps the inboard skin in kits that have
pre-punched skins. Prior to the pre-punched skins, it was the opposite.
IF you don't have the pre-punched skins, it really does not matter.

The other one goes through the two skins only.

My pre-punched skins have a 1-1/2 inch overlap.

I am at work and just read the attached message. While I am not at home

Possibly they are in the converter rather than in the base itself, but
when I bought the stuff from the auto parts store they emphatically
warned me that they (isocyanates) were there and that the only way to be
safe using the stuff was with a positive ventilation system. I use my

cautious on this one that hope I'm being just careful enough.

No, Veriprime does not contain isocyanate. If a paint contains
isocyanate, it will say so on the label. As a general rule, it is the
polyurethane paints that contain isocyanate. Normal acrylic enamels and

I used Corlar on my BD4 several years back and I liked it a lot. It made for
a beautiful prep for the IMRON. However, it was very expensive, and as I
remember, contains isocyanates, (which are really not a problem if you are
careful). I used Vari-prime on the RV6 since it was handy from the
construction phase. One nice thing about it is that you can topcoat as soon
as it flashes off, which saves a lot of grief when making spot repairs or
additions to the primer (which you will discover just when you are getting
ready to paint.
To get the same "non-sanding" substrate as the CORLAR you must apply it like
they say on the can, otherwise it will not be smooth and will interfere with
the flow-out of the IMRON. Its a problem with flowout (leveling). You must
get enough Vari-prime on to flow and dry really smooth, which facilitates
leveling of the IMRON.
The light grey color of CORLAR lets the true topcoat color show, whereas the
Vari-prime darkens it somewhat (depending on the topcoat color) .
You should look at Kent's 6A paint. He used 2-step acrylic enamel. Clear
coat applied with the HVLP gun is severely orange-peeled (in spite of
addition of reducer), while application with a standard gun is crystal clear
(smooth, that is). He probably will have to strip the fuselage and wings,
otherwise he will have many days of "buffing it out". Problem with that is
that its METALLIC paint, very hard to buff out and look good....
I think I would consider acrylic enamel (2 step) if I had it to do over
again. I am getting ready to attempt spot repairs to my IMRON very soon. I
have not had much success in the past.
Be careful with the size of your exhaust fan. I used a large attic fan as
you suggested, and it moved so much air it stirred up dust from the floor,
etc. which promptly settled into my paint!
Have you seen my previous posting regarding water removal from your air
supply?

If you plan to install the full swivel tail wheel (which IMO you should) let

the correct tail wheel spring.
Additionally, If you are installing electric elevator trim, let them know
because they will omit the cable at a $50? credit.
And as you know, now is the time to let Van's know if you plan on a
slide-back canopy and electric flaps.
I'm sure that there are other things to add to the list but I built my

Dupont says you can use either Colar epoxy 2 part primer (the one they
prefer)
or Variprime (self etching). From what I have read, the Variprime
is a non-sanding primer and can go on fairly thin.
The Corlar, they recommend a light sanding and it can coat 0.7 to 1.5
mil
thickness. I like this one because it is a light gray color and is
recommended under light paint colors.
Does anyone have any ACTUAL experience with either of these primers or
have
I have used both in priming the interior parts of the plane. The Colar
dries to a shiny finish and is much harder than the variprime. Because
of the gloss finish on the Colar, I would think sanding would be a must
whereas the Veriprime dries a flat dusty looking finish. I am using
Colar on all my non-alum parts. I plan on leaving this the final coat
on things like the rudder pedals. The Colar is more of a hassel for
small prime jobs as it has a 3 hour induction time where variprime is
ready after mixing.

Could someone educate me in a little detail about the forces that act on an
aircraft during a tail-slide. The way I see it....
On the way back down, it would seem like the aircraft would have to fall
over before 30mph or so (power off). And when it does 'whip' around, it
would seem like the engine mount wouldn't experience any more abuse than
180hp of torque, or an 6G pull with full power. And if the speed is around
30mph in reverse, is that really enough to cause control surfaces to break?
It would seem to me that if you pulled full deflection at 135mph or so, that
would put far more stress on the surfaces than 30-60mph in reverse.
(assuming one maintains control of the surfaces and not let them bang
around) Doesn't that squared force rule apply to these airspeeds?
Could someone please clear this up for me.

Rion Bourgeos bought a used one and said it was more hassle than it was
worth, and that he'd just use the Avery tool if he had it to do over.
He said the trouble was with keeping it supported square to the spar. I
suppose Van's maybe has some set-up for theirs where that's a non-issue
though. Rion sold his to Kefton Black and Mike Seager, both of whom
are building their second RVs. They had no troubles, although they
squeezed their rivets as a team which probably made a difference, as
Rion was working alone.
Personally I recommend just using the Avery tool and a 4lb hammer --
that's what I did and it was easy (2 hrs to drive the rivets in the
first spar, 1.25 for the second, no helper needed).

We were discussing this not too long ago. With high pitch or yaw rates
(off-axis to the crank/prop) the spinning prop/crank combination will
experience gyroscopic precession 90 deg off-axis to the rotation (if I could
send pictures of my hands it might be clearer :). The higher the 'rate of
whip', the higher the off-axis force. It can be a higher load (force) than
the engine and mount feel during a 6-g pull, but it's highly dependent on RPM
and the "whip rate" - pitch or yaw rate when the hammer falls.
> And if the speed is around
> 30mph in reverse, is that really enough to cause control surfaces to break?
It's enough to slam the surfaces agains the stops pretty hard (harder than
you'd do with yor hands against an opposing airload). The stops aren't
super-strong, either.

But you're not slamming the stick against the stops during this full defl.
pull. The snatch can also come when you aren't expecting it, and can
jerk the stick out of your hands even if you intend to hold it in place.
(It makes a pretty evil noise, too. :)

I agree with you, I used the same method as you and found the rivets turn
out beautiful. My only recommendation is that you make absolutely sure the
spar is totally perpendicular in all directions to the Avery tool. (I
found if you are off in the slightest, those big rivets aren't very
forgiving and bend over real easy) Also, make sure the spar flanges and the
whole spar in general is held together very tightly, otherwise the pounding
will cause the spar flanges to separate.

Well since you only get the full size plans for the part of the subkit

The physics doesn't change. But the direction of the force will. Some
materials (or designs) are stronger under tension than compression. If the
design is adequate under tension it may buckle under compression. Check out
the "load path" on your push rods - they work best under tension!

Absolutely. I've posted this more than once (aplolgies to old-time
rv-listers) but for those who haven't heard "the word": clamp or screw
some wood blocks to the ends of the spar such that it will rest on the
floor perpenduclar in both directions to the shaft of the Avery arbor,
with the factory head of the rivet just lightly resting in the die.
Also use some shims closer to the arbor to keep it from sagging. Then
you can just move the avery tool and the middle shims along under the
spar as you go.

From: | "Brooks, William" <brooksw(at)crl1.crl.aecl.ca> |
A note to introduce myself.
I am building an RV-6A in Ottawa, Canada. I have completed the empenage and
one wing and am now drilling the skins on the second wing. I had absolutely
no experience in aircraft construction or metal work prior to this project.
Some general comments from someone who has never done this before that might
be helpful to those who are just beginning.
1. Rivet holes for AN4 rivets should first be drilled with a 3/32 or #41
drill. If you start a hole for an AN4 rivet with a 1/8 drill, some holes
will inevitably be messed up and too large.
2. Be careful to maintain minimum edge distances.
3. When constructing the wings, insert and tighten the bolts that hold the
ribs to the main spar before you position and drill the leading edge and
main skins ie. do not rely on clecos alone to hold the ribs in place. When
the bolts are put in and tightened, they will shift the ribs just enough to
misalign some of the rivet holes you have just drilled in the skins. One can
use non locking nuts for this temporary fastening.
4. If one buys a 4x4 to use as the horizontal member of the empenage jig
from a lumber yard in Canada in January, it will be frozen solid. The
straight line carefully marked on the 4x4 and then used to locate the hinge
line for the horizontal stabilizer will no longer be quite straight some

been built.
5. A portable 220 volt 5500 watt construction heater ($80. Cdn) will
quickly and easily heat up a somewhat insulated single car garage.
6. The Scotchbrite wheel is a great invention.
7. If you are countersinking anything, the piece being countersunk must be
backed up with another piece (usually the underlying rib if you are doing a
skin) to positively locate the countersink bit, otherwise the bit will
wander and the hole will be oval.
8. If it isn't right, scrap the piece and do it again. Van's Aircraft are
happy to send you as many replacement parts as you ask for, and they are
very prompt to ship.
9. The Orndorff videos are helpful and a confidence builder.

The advantages to the full swivel tail wheel are 1) tighter turns while
taxiing and 2) it's MUCH easyer to push the aircraft around on the ground.
Without the swivel option you will find that you are always picking up the
tail to swing the aircraft around. This may not sound like a chore now, but
I can tell you that after building my plane, my back is shot. It's much
easyer to push it than lift it.

Union Delays Plan for Clearing Customs by

Just as the U.S. Customs service was set to put in place
a plan that would allow pilots to clear Customs by
telephone, the program has been put on indefinite delay.
The streamlined program--which had already been adopted
by Canada--would have allowed pilots returning to the
U.S. from Canada to clear Customs by telephone, without
formal inspection.
According to a Customs spokesman, the employee union
representing Customs inspectors objects to the program
because of "law enforcement concerns." The union has

The only reason for using the water filled tube is that you know exactly how
many pounds of pressure you have applied and can also see any slight
variations in drop of the water column indicating a leak. I used clear
plastic hose with food colored water. Used a hair dryer to warm the end of
the tube so it would fit over the fuel inlet fitting tightly. Used duct
tape to seal off the fuel filler hole.

Subject: | Re: RV6 Kit options in advance |
Gary,
Your points are well noted. What I have found on the RVs I've been
flying in (and taxiing in) is that you can still get +/- 90 degrees of
tailwheel movement with Van's stock tailwheel, therefore no real
advantage with the swivel unit.
With respect to pushing it back, I've seen a lot of clever designs for
tow bars which does not add any weight to the basic aircraft.
The one issue that hasn't been mentioned yet, is the raising of the
tail by approx 1.5 inches. Yes this will give you better visibility
when taxiing but the drawback is on landing. What I have noticed to
date is that on the RV models, there is a tendency for the tailwheel
to hit first on landing. Van even recently extended the RV-4 gear to
ensure the flare attitude is the same as the three-point attitude to
reduce the probobility of this happening. By going for the full
swivel tailwheel, you WILL be screwing up the designed flare/3-point
relationship since the full swivel hangs down further. Hitting the
tailwheel even sooner will cause the mains to hit harder (could
contribute to those loose firewall rivets we've been reading about).
Anyway, this was the criteria I used when, after much deabte with
myself, I decided to stick with Van's design. Most of Van's decisions
were made for a reason.

I've heard through this list that band saws, drill presses, belt sanders and
bench grinders (among others) are good things to have. Can you be more
specific? Sears is having a big sale this weekend; I stopped by this week
and was amazed at the differences between the different models. So, my
questions are:
a. band saw - tabletop or free-standing?
- how "deep" should it be? (10", 12", 16")
- what are the min and max speeds it should be capable of?
- what type and number of blades should I include?
b. drill press - same as above
- desired horsepower?
c. belt sander - 1" belt or 4" belt?
- horsepower/speed?
d. bench grinder - 4" or 6" wheel?
- other important options/considerations?
All of these things have a ton of available accessories. Which ones are
important? I'll no doubt use them for building the jigs too; are there
things I'll need for the woodworking aspects that are in addition to whatever
else you come up with?
I may also buy some of this stuff used (auctions, etc.). What things should I
watch out for when buying used?
I'm still a ways off from convincing the wife, but I figure if I load up the
garage with tools, eventually she'll want me to use them. <;^)

I just ordered my fuselage kit and told them I wanted the springs for
the full swivel tailwheel. My kit won't be ready for shipment until
11/20 so I have some time to decide if the swivel tailwheel is worth
getting. My Citabria has a swivel tailwheel which I would hate to be
without, but how that relates to an RV-6, I don't know. Haven't priced
the swivel wheel for the -6 yet. I wonder if my landings will be
precise enough so that 1.5 inches will make a difference. Anybody else
have some thoughts. How much extra money and time are involved with
the swivel wheel? Can you experienced RV-6 drivers tell the
difference?

Table top should be ok. Any size will do in fact, but my experience
with the small variable speed Sears bandsaw is that it's pretty
el-cheapo. I finally made em take it back after it broke (still under
warranty) and had a big fiasco trying to get them to fix it right. The
bigger floor models look to me like they are built a lot better. Delta
12" table top is pretty good too, that's what I have now. You can get
away with fixed speed (my Delta is fixed speed) but it's kind of nice to
have variable speed for the few times you're cutting steel.

You should find the zinc chromate easy to remove with acetone (maybe
MEK?) and a scotchbrite pad. That's one of the drawbacks to zinc
chromate, its not real resistive to solvents.

Ha Jim!
In response to your too questions, I just went through all that and I would
say don't make a big deal about it. You seem to have time on your side as I
did, I would suggest a few things here. The rule of thumb for me was on the
larger items, get the biggest, best I could afford. You will have these
things in your shop for years to come and you WILL learn to rely on them
alot.
1.) The saw was a real problem for me. I scratched around for a long time in
making a decision. I finally ended up with a Delta 14" floor model. This was
more than I wanted to spend but now I am very happy I bought it. ($650.) I
got the roller base as a "free" gift special and found that to be a great
add-on. The saw weighs alot and with the roller base you can move it easily.
It has a 1/2 HP motor that does well. If you want to be more conservative you
can find a saw at Sears made by a company named, I think it was Robi...? It
is much better made than the Sears bench model. I looked at the Black and
Decker and Delta bench units also. The Robi or the Delta would be the best
choice. My problem with the bench units is they are small and underpowered.
One fifth HP is not very much but it will work on "normal" things. I would
not bother with variable speed saws unless you plan to cut steel or iron. For
aircraft metal the constant speed saw with regular 1/4" wood blades (6TPI)
work fine with some minor cleanup after the cut.
2.) I did buy a Sears 13" 2/3 HP floor model drill press. After looking at
everything from light industrial to junk I found this model to be a great
value. ($249.) Most of the presses in this size range are made in China by
one or two plants and they change the name. The 13" is variable speed and
works wonderfully. Be sure to install the chuck as straight as possible when
you assemble it or the bits will "wiggle."
3.) I have a Sears 1" belt sander, 1/2 HP with a 6" disk attached. This saves
a lot of time and has been great to have. Why file when you can sand... Ask
the sales person if they have last years model availible. There is no
difference and it cost half what the current model is selling for. ($149.)
4.) On the bench grinder I think I could of done better. I bought a Black and
Decker 6" unit from WalMart. It was only $39.00 but in my opinion is kind of
cheap. It works well enough but it is not balanced perfectly and I have
always been cautious when it comes to spinning things that could come apart
and remove your head. Just a thought. I think 6" is big enough but I would
opt for a better quality unit next time around.
You can figure on spending another $6 - $800. on aircraft specific type
tooling. That list can get long. Check out the RV home page for a good list.
I suggest you won't go wrong by shopping with Avery (1-800-654-8379). Bob
will be of great help in answering your questions and you won't find better
customer service anywhere. His prices are fair also.
One last thing, DON'T buy a diaphragm type "oil-less" aircompressor. They
make too too much noise. Get a piston type, one or two stage with a 20 or 30
gallon tank, 1 HP or BIGGER. It is the CFM that counts here. Lots of volume
is better. 10 CFM is not too much but less will work if all you use it for is
riveting.
Hope this helps and saves you some trouble.

I prefer a table top since I don't use it much and I can store it under
the workbench. I have the small 2 wheel Delta (8 inch?) with a standard
wood cutting blade. Cuts Al. like butter but does leave a rough edge. I
don't think you need to cut any steel for an RV, so the variable speed
isn't a necessity.
> b. drill press - same as above
> - desired horsepower?
Speed is more important than horsepower. You need to turn < 500 RPM for
using a flycutter (to cut lightening holes) or drilling steel. Mine goes
down to 200 or so. Definitely get a free standing. You'll use this a lot.
> c. belt sander - 1" belt or 4" belt?

Don't have one. Haven't missed it. I just use a grider & scotchbrite
wheel for dressing edges, etc.

Get a 6" with sealed bearings. They're still pretty cheap.

A skilsaw is handy for building the jigs. Apparently a table saw works
great for tapering the wing spar flanges, but I used the bandsaw.

Yes, but the other way aound, since the F-649 is the removeable piece, you
might as well put it on top.

I presume you are refering to the baggage floor flange at the bottom of the
parts.
I angled both flanges back to give a neat 60 degree angle at the bend. I
cut back the F-649 floor flange so that it stopped at the F-624 edge.
I made it so that the F-650 (the fixed piece) had it's flange under the
floor panels, and the removeable F-649 has it's flange above the floor
panel. I cut the F-649 so that it slides backwards over the flap actuator
tube (electric flaps version) per the George O. video.
I have also seen this F-649 piece made such that the floor flange is under
the floor panels, and the F-649 panel now must slide downwards over the
flap tube. If you are going to carpet the baggage floor, I think the way I
did it is a little easier. If you don't carpet this area, then the second
way will look a little neater. If you are building the manual flaps
version, then the flap cross tube is ahead of the F-605 bulkhead, and the
second way would probably be better.

Here's my thought's on tools for RV's.
My basic premise is based upon the fact that I love to build things
and will continue to use these tools long after I finish my RV. I try
to buy the best made tool that meets the requirement of the job and
possible future jobs, while trying to keep costs reasonable. Reason
costs vary considerably from person to person.

For cutting aluminum you want a high speed bandsaw like those used for
woodworking. A 3 or 4 tpi hooked tooth blade works best. The finer
tooth blades designed for cutting steel gum up much too quickly. The
depth of the cut is probably not too important for most RV
applications.
For the quality of cuts you need for the metal work in an RV a bench
top model would work fine. In general I prefer floor tools to stand,
because I never have enough bench space. The bench tools I do have, I
have build a mobile stand to allow easy portability and not take up my
bench space.
> b. drill press - same as above

A wide range of speeds or belt ratios is desirable here. Most drill
presses have plenty of horsepower. If you are also interested in using
this for woodworking, the floor model is definitely prefered here. I
would want at least 12" of throat depth here. More is better up to a

I have a 1" belt with and 8" disk on the side. I use it constantly
for cleaning up and shaping parts. The 1" belt makes working with
small pieces easier. Though a 4" belt would be more useful for

Subject: | RV6 options. was: RV4 Kit for sale |
I just thought of another two RV6 options....
1. Apparently Vans will special order canopy tint options. It was in
a bit of literature I saw a few years ago, but was not on any of my finish
kit option questions, even when I spoke to the help line.
Std. is a light grey tiny ....
Option is either clear or darker grey.
I would guess they might entertain a special order ($$) tint (e.g., blue or
bronze) if you really want something special. Talking to sailplane canopy
makers, as long as they can get what you want in Plexiglas, they can mold
it!
2. Steps (left and/or right) if you are building a RV6A. They can be
retrofitted, but are much easier to build in before the baggage floors get
installed. These are offered in Vans Optional Parts Catalog.

Subject: | CNC Milling Machines... |
Hello Everyone,
Since there appears to be a number of tool experts on the List, this seems
like a natural place to ask this question.
I have an machined aluminum (6061 T6) faceplate in the fuel managment product
I'm working on. I just got the word from the machinest that I have used in the
past that the price he quoted me in the past was actually way too low.
I'm now looking at a significate increase in product cost due to more
expensive machining work. I have shopped around both locally and across the
country and prices seem pretty consistant.
So here's the question. I noticed in the back of Sport Aviation a couple of
ads for "home" milling machines by companies like "Smithy" and the like.
They indicate that prices start at around $1000. What do you get for $1000?
What is the quality of these machines? Most importantly, what are the
CNC (computer interface) capabilities of these machines. I have plunty of
computer experience and an available system to use for this purpose. Can
I get anything in a CNC mill worth buying for, say, under $5000?
The parts I need to make are about 2.5" x 2.5" x .357-.5". Any information
and insight into this area would be most apperciated.
Thanks,
Matt Dralle

Monte 'et all,
I just tried the latest version of Eudoro Pro (V2.1.1) with the messages from
the RV-List. In the "Who" field, appears the actual sender of each mail.
You might try getting the latest version of Eudora - 2.1.1 has a lot of nice

I have an RV-6 180HP constant speed Hartzell---installed an ACS full swivel
tailwheel with the modified tailwheel spring. There really should be no
noticeable difference with the original tailwheel if you use the modified
spring. The RV-6 will not fully stall in the 3 point position anyway. The
full swivel wheel is great to have in turning, parking, etc. The RV-6 is
fairly easy to land anyway so I wouldn't worry about any problems with
landing. It is slightly heavier and can be sheared if you catch it in a ditch
or hole while turning. Since I have the heavier engine and constant speed
prop up front the liitle extra weight in back actually helps! I have no

Can you be more specific? Sears is having a big sale this weekend;
I stopped by this week and was amazed at the differences between
the different models. So, my questions are:
I have a fairly small Sears table-top drill press that is OK, but
if I had more money I would have bought a larger one. I don't
own a belt sander, so will be interested in the responses. As a
result of the chatter here, I just bought the Sears band saw --
10 inch variable speed -- that I hope will be fine.
The real reason for this is that I am using an older bench grinder
that I had for several years. It has shields for both wheels. My
advice would be to get one that has the wheels very sitting out
there by themselves. You will want to put a scotchbrite wheel on
one side and it is much easier to work the piece of the wheels are
not encumbered with shields, as mine are.

Subject: | Re: Tool Specifics |
Jim, I wish I had the RVlist to query when I was buying tools. You want
the deepest throat on the band saw you can get. Anything else is icing on
the cake. I went for floor stand models simply because I can only have
so much table top space, and I can walk right up to the machines and use
them, without having to clear a space on a tabletop, move the item into
position, then when done, put it away and get back to whatever I was
doing on the tabletop before I was interupted.
Many guys on the list say they use a wood blade with no problem, but
since I pretty much put woodworking on hold while I build my bird, I put
a metal blade on the bandsaw, and anything I have had to cut in the way
of wood had been cut on the metal blade. I figure wood will not affect
the metal blade as much as metal will affect a wood blade. Speed isn't
that critical on the band saw when cutting aluminum.
Drill press... I have a floorstand model, same reason as above. It gets
down to 500 rpm. and this seems to be ideal for most of what I have to
drill, as well as working fine with the flywheel cutter...WITH THE PROPER
PRECAUTIONS!!! If you have any questions about those, ask. I have
developed a reliable method of cutting lightening holes without risking
life, limb etc..
Belt sander... 1" belt sander is invaluable!!! The more horsepower the
better, much more important than speed. You won't want it to go very fast
anyway. Mine is single speed, fairly slow. This is good, you don't want
to build up too much heat anyway.
Grinder... When I got my belt sander, I put the grinder away and haven't
used it since. I chuck my 6" scotchbrite wheel (and the smaller ones too)
into the Drill press on 500rmp, works extremely well!

I have retrofitted a full swivel tailwheel to my RV4 and I think this is
one of the best changes I have made to my aircraft. I don't have any real
problem with the tail hitting first other than you should be carefull
during a full stall landing to touch the tail wheel down easy. You can
damage the bottom of the rudder with the top of the tail wheel attatch
bolt if it contacts the rudder during a hard landing. I have not had any
problem with this but it is something to be carefull of.

Hi Dick,
I finished the vertical stab on my RV-6 several months ago.
Yes, I think there is always a considerable amount to cut off the
skins. As several of our very experienced members keep saying,
don't cut any sheet metal until you absolutely have to. That is,
keep your options open as long as possible.
I used an air die grinder (about $35 from Harbor Freight, but I think
I got mine on special for about $20) with a 3 inch (1/32 thick) cutoff
wheel to cut my skins. To keep me from wandering into the "good
stuff", I bought some 3/4 inch aluminum angle iron (2 ft and 3 ft
length after cutting). I put tape on the outside of one side and
c-clamped it to the skin next to my marked cutting line. Worked
great for me and doesn't bend, suage or mark up the metal. A
little clean-up with file and scotchbrite finishes the job.
Hope this helps.

That edge of the delivered piece is simply the edge of the aluminum
sheet, so it won't be anywhere near corect. As I recall, you'll need to
trim a couple of inches off at the tip anyway.
I trimmed it using a combination of shears (for the flat, straight
portions) and a cutoff wheel in my dremel tool (for the leading edge). I
cut it about 1/16th inch long, and then filed it to the correct size.

Addendum on tools.
I notice a lot of comments about floor model vs table model power tools.
I also am short of benchtop space but I'm also short on floor space.
(Work in the garage). I solved the problem by taking a page from Tony
Bengelis who suggested in one of his books that you mount your bench
tools on a rollaround stand. I did just that. My stand is 32" X 32" and
I have a drill press, a 1"belt/8"disc sander, a vise, and a grinder
having a scotch wheel on one end and a fine grinding wheel on the other.
These tools are positioned such that I can operate them all without any
interference. When I close down for the day, I just push the rolling
stand against the work bench and pull the car into place. It could'nt
work better, and the tools are always handy and together.
PS. Dom't sand aluminum with a grinding stone, it loads it up with
aluminum and you constantly need to reface it.

Subject: | Drilling F-673 aft side skins |
I am currently drilling my aft fuselage side skins, and had a question about
drilling them to the main longerons. Vans recomends a 1" spacing, but only
drilling every third hole because of fitting the f-674 and f-675 top skins
later on in the construction. When you install these top skins, you then have
to dimple the top skins, and countersink through the side skins into the
longerons.
I was wondering if anyone had done this differently. What I thought about
doing was to go ahead and drill all of the holes, so I could countersink the
longerons, and dimple the side skins. Then when I put on the top skins, I
could just backdrill through all of the holes. Doing it this way would leave
more material on the side skins because they would be dimpled instead of
being countersunk. Any comments?
Thanks,

I use it at 500rpm in the drill press and it works fine. BE CAREFUL not
to get a corner of the piece pointed upstream on the wheel, it could
become a missile. The primary advantage of the drill press vice the
grinder mounting is the ability to get at the wheel from all directions
with out any wheel guards or covers getting in the way, but as noted
recently, the grinder isn't much good for aluminun with a grinding wheel
because of the aluminum clogging the stone, so you don't need the grinder

I'm installing wing tip strobes, and am trying to decide whether to use a

I have heard the argument that the power leads going to the power source
should be short to minimize radio interference. This would suggest using a
single central power source.
I've also heard that the wires running from the power source to the strobe
are a source of radio interference, and should be minimized. This would suggest
a power source in each wing tip, near the strobe itself.
Which is right?

A couple of questions on brake pedal location.
I am fitting the pedals to my 6A. I am tall (6' 5") and a lot of it is leg
so I wanted maximum pedal room. On the plans Van calls out to locate the
bearing block 4" from the firewall "variable" according to height but does
not nominate a forward limit. Obviously at some point the pedals or brake
hardware would foul the firewall. Does anyone have a feel for the forward
limit on this location...... or does anyone with a completed plane know how
much clearance they have with full pedal displacement and the blocks in the
standard location?
Also......at least one builder here has jacked up the bearing blocks on 1"
spacers to elevate the pedals so as to avoid inadvertantly applying brakes
during rudder application. Does anyone else have any experience with this
mod? I remember Frank Justice asking for input on this some time ago but I
never saw any outcome.

Mark
I just went thru this issue three weeks ago. The way he recommends works out
fine. When you drill the holes in the top skin, at 1" centers, you note, you
just csk the holes in the rails thru the side skins. Dimple the top skin,
and you have full depth of these for strength. The side skins are under the
top, and even if not thick enough for a csk in the normal case, will be held
by the top. Also note the 1" spacing is different than almost all the rest
in the fues, 1 1/4. This helps make up for the slight loss of material.
What you have to watch out for is the area at the tail where there is no top
skin, i.e. from the tailpost to former F 609. Here you need to do the 1"
spacing now. Also, if you are doing a sliding canopy, there is a small area
where the top deck skin does not overlap the side skins. I wonder how many
ships have csk side skins in that area?

My 6 had 180 HP+constant speed. I put the battery in the normal place and the
c.g. was near the forward limit. On short final I would run out of trim and
have to hold a lot of stick, too much. I considered remaking the trim tab or
moving the battery, but finally just bolted two 5 pound pieces of lead to
the thing, just under the empenage fairing. Moving the batttery entails
other problems. You would have to design a special box, use heavier wiring
(#0 maybe) , and give up some of the limited baggage space, all not good.
Dang it I hate to haul lead around, but it cleared up my trim problem, and
was so simple. I was able to gross it to the 1800# I have on the data plate,
with the c.g. at the aft limit. It will be interesting to see where the
c.g. falls when I complete my 6 to 6A conversion.

Since the cables are shielded you should not get much radio interference.
You should not run them close to your antenna wires. The d.c. wiring to the
strobe power supply will cause problems to your mag compass if they are too

I was originally going to install remote power supplies (one in each
wingtip and one in the tail). HOWEVER, in the meantime, Whelen
discontinued the 20 joule single-strobe dual-flash power supply. Whelen is
switching over to the comet flash supplies. The comet flash supply that
will power three strobes is only 20 bucks more than the one that powers
only a single strobe.
The bottom line is that you can still go with remote supplies, but it is
cost-prohibitive to do so.

Dick,
We have all had to trim. George and I don't trim any of the skins until
just before riveting and then we still leave some to be finished after the
riveting is done.
The trick to a straight finished cut is to sneak up on it. Only cut off
half of what needs to be removed at a time. When you get down to 1/16" to
1/8" left, use vixen file. It will remove a good amount of material at a
time, but will keep the line straight.
You might want to trim the vert stab and the rudder at the same time
giving you a better chance of getting a nice straight line between the two.
With the rudder mounted, the required line might look different than with
the two pieces separate.
Happy building and good luck!

Subject: | Battery location |
My RV-6A has a Lyc-0360 with the Hartzell cs prop. With the battery in the plans
location plus the extras I have on the aircraft, the cg came out .3 inches
forward of the of the most forward cg location shown on the plans. As a result,
I can load the aircraft to my gw limit, 1750 lbs and never get near the aft cg
limit. However, the aircraft is fully trimmable at all airspeeds with the MAC
electric trim on the elevator. As I slow down from cruise speed to landing
configuration, solo, the amount of trim needed is considerable but then the
speed range is also considerable so it all evens out. With a passenger the trim
needed is less as the cg has moved aft.
At full flaps (a little more than 45 degrees) and full fuel, solo, the movement
of the trim tab is very noticable and uses most of the trim available.
Overpowering the full trim tab positions in flight takes some effort but is very
managable. The forward cg tends to make the aircraft more stable but stability
in flight is hard to define when you are in cruise. When the aircraft is all
trimmed out it is all relative to the person flying. On takeoff with the trim
tab in neutral, I pull a little up elevator to break ground at 80 mph. with full
fuel. That is when I notice the fwd cg. solo. As the speed increases it becomes
less noticble and is easily trimmed out. I took Van's Aircraft advice and left
the battery in the forward location. The aircraft has been spun, rolled and
looped (not by me, had a good aerobatic pilot available) and the pilot said that
it does a nicer roll than the RV-4. The other manuevers were routine. The
aircraft now has 166 hours.
BTW, I weighed the aircraft on bathroom scales so the cg could possibly be
closer to the forward cg range. The only part I don't like about the forward
battery location is that it is very difficult for me to get to the battery with
my "plump" midriff. Seems I just can't bend in the middle as I used to when I
was skinny.
Hope this helps

Subject: | Re: Drilling F-673 aft side skins |
The problem with drilling all the holes and then backdrilling the skins is
that you run the risk of enlarging the existing holes. This is especially true
if the holes are countersunk first since the hole will have less material
thickness at the hole. The other negative factor would be that there is less
material to guide the drill bit to keep the holes in line. The drill bit may
be able to tilt a little and as a result, the holes in the outer skins will
not align with the inner skin after dimpling.

you
would have not problems going back to 2.75 inches and still maintain
clearance for your brakes fully activated. Check it and also make sure
your
feet can get behind the pedals when that far back.

Dan:
For floor insulation I used a closed cell foam product from Sruce &
Specalty. I then put a metal floor on top of it with screws so the area could
be checked later.
On the firewall I used a open cell, metallized (alum on mylar) foam that
had an adheasive on it. This was availaable from J.C. Whitney. Iused the same
material on the sidwalls, then covered it with the apolstery.
Hope this helps....

One method is to get a 'drill guage'. These are $10.00 from Avery.
They have all the Number drill holes (# 30, #40,...etc.) and you
can simply slip a bolt in the hole to see what the best fit is.
It also comes in handy to double check a drill bit diameter befor
you use it as some of the bits are hard to read the size and after
they all get mixed up it can be a problem.
Avery also has a number of the common reamers in stock.
In general, you don't need to worry about reaming holes in a RV.
The critical holes to ream in the spar are already reamed.
The only other place to ream may be the rear spar attach bolt
hole. I just used a close tolerance bolt in it.
The main gear and tail wheel bolts could also be reamed but I did
not find it necessary. The main gear comes predrilled now also.
The Avery catalog also has a full page of the wire guage sizes
and their decimal equivalents. Their number is 1-800-652-8379.

I would recommend separate center posts. I found myself reaching into
the wing a lot through the lightening holes. The distance between
should be enough for you to squat or sit between them.
Ross Mickey

---- Begin Forwarded Message
I'm currently laying out my workshop, including lighting and such like,
and I
have a long, relatively narrow space where I believe that I could jig
up two
wings, end-to-end, and build them both at once. My question to the
list is
whether or not the centre post can be shared, or is it better to have
two
centre posts, one for each wing, and separate these posts by some sort
distance. If the latter is the case, what would be the minimum
practical
distance between the two centre posts?
Any of you that are currently
working on your wings (aren't we all?), I'd appreciate a little advice!
Thanx...

Gary, Have a -6A with just about 600 Hrs in two years. Have a 160HP O320-D1A

Climp suffers a little as a result of the heavy pitch, put cruise is what I
wanted. When you can still climb out at over 500 FPM with two 220lbs bodies,
full fuel, (and a bit of frost on the wings) I don't think that's too
bad......

Vans sells a samll book entiltled the Standard Aircraft Handbook,
for about $9.00, the cheapest price I've seen, it covers all of the
questions you are asking and more. This is a great reference book for
anyone building, maintaining or restoring an aircraft. It also has
torque tables, drill and bolt guide, wire gauges, plumbing etc. I highly
recommend it.

You don't buy these. You just make it.
They simply put a pair of the hinges on it so the hing pins are
on the inside of the cowl. You then route the hing pins to the
front air intake and glass some form of a guide to guide the pin
to the hinges.
I was going to to this and then blew it off as too much hassel
and went with Van's KISS approach.

Tony Bingelis has published drawings for his firewalls (both his -6
and his -6A). The -6 version is in March 1990 Sport Aviation, and the -6A
version is in his new "About Engines" book.
I too would like peoples opinions about the layout suggested in
these diagrams, since it seems to be that it would be much easier to drill
the firewall holes, and attach the required nutplates, etc. _before_ the
motor mount is attached and the engine hung.
... awaiting comments .. Gil Alexander, RV6A
PS. I will send a copy of this article for a SASE if anyone can't get back
copies. Perhaps it would be worth John Hovan scanning it for his RV home
page??

I don't want to open the old 6 vs 6A arguement again, but I was curious
what your reasons are for doing the conversion. It would seem like a lot

Monte 'et all,
I just tried the latest version of Eudoro Pro (V2.1.1) with the messages from
the RV-List. In the "Who" field, appears the actual sender of each mail.
You might try getting the latest version of Eudora - 2.1.1 has a lot of nice
new features anyway. Among other other places, you might try anonymous ftp
to ftp.llnl.gov and look in the /eudora directory for the latest version.

Also though no-one will believe this, I think there are small elven type
creatures whose job is to walk around behind you moving tools. After you've
walked around your wing two or three times muttering about "I just put the
Damn thing down, now where is it" and looking for something, you might also
belive. It's amazing how far you travel in search of tools when you have
something in a jig and have to walk around it.
I think they also walk about in the house moving remote controls and key
rings, but this is just my opinion.
