Hi Gary,
The answer is to not be insuch a hurry. I was riding with John Morgan (from

oil started to get hot, he said its not worth the trauma to the engine. We
pulled off to the side and waited for the line to shorten.

Charles,
Maybe your Mac grips have extended the length of the sticks a significant
amount and it wouldn't hurt to do a little trimming, but be aware the
fabled RV feel is predicated on the standard stick length. A shorter
stick will mean higher control pressures and more sensitive controls; an
unhappy combination.
In cruise, where feel doesn't matter, it is always possible to grip the
stick down below the grip.

For what it's worth, I had to cut my control stick down. I didn't use a
stick grip other than a bicycle sponge cover, but if the stick was moved all
the way forward, it would hit the bottom of the instr. panel. and not get
full movement. I figured with my poor flying, I would be doing a lot of
spin recoveries, so I cut it off short enough that with my thumb on top of
the stick, it would clear the bottom of the instr. panel. Worked for me.

I love my MAC grips. While I flew with military grips for years, I find the
spongy MAC to be far superior, perhaps because I don't wear gloves while
flying any more. My only problem is the elevator trim buttons do not seem to
be in just the right place for easy thumb trimming on take off. Some day I
will try a different kind of button than the flush ones, but don't want to
screw with it right now for such a minor thing.
I cut about an inch and a quarter off each stick, but now after much trial
and observing others fly with my stick, I believe you will be happiest with
the MAC if you sit in the plane in a relaxed fecal position and see where
your flying hand naturally falls along the stick. The bottom ridge on the
grip makes a marvelous 'rest' for the bottom of your hand, so you want its
height to be the same as (or slightly higher than) the "at rest" position of
your hand.. You would then cut accordingly. BTW I use the forgoing
scientific term for the sitting position that one assumes for a bowel
movement while seated on an indoor facility.
Needless to say this is a very subjective view, but I must say all who have
tried my grips have remarked favorably.

Bob,
Thank you for the great troubleshooting tip. I have one
comment/question. Most folks don't have oscilloscopes. On auto
alternators, I've accomplished the same test by opening up the
alternator and testing the diodes using an ohmmeter.
A good diode will show zero or low impedence in one direction, and high
impedence when the ohmmeter leads are reversed. A shorted diode will
read low in both directions. An open diode will read high in both
directions.
My question is: Having never disassembled a certified aircraft
alternator, can this process be used in that type of application also?

Sure . . . don't tell anybody . . . it's a state secret . . .
but there isn't a nickle's worth of difference between
"automotive" alternators and "certified" alternators
excecpt when there IS a difference, the automotive one
is better.
Yes, the ohmmeter check is equally valid on both styles
if one can deduce where to put the probes and assuming
the test points can be reached. The downside to the ohmmeter
check is a requirement to open the alternator and unhook
the stator leads from the diode stack before you probe
the individual diodes for testing. The d-cell/o'scope
test the writer described works on an assembled alternator.

Find a good auto electrics repair shop - especially when putting it into the

"ohm out" a component of any kind without removing it from the circuit; in

Subject: | Canopy, . . HELP!! |
My name is Rich. I have not written to the RV-list before. I guess I have
just been lucky dealing with the many problems along the way so far.
Thanks to the many who have given advice on the RV-list. I have enjoyed
reading the assorted e-mails for a year or so. I have learned a lot.
I am building an RV6A, slider (have been for two years now). I just
finished rough trimming my RV6A canopy and fitting it to the fuselage. My
first thought is that it would fit. It now appears that it won?t in the
front.
I did opt to do the option for added passenger height. The roll bar is
installed 1/4 inch higher, and 1/2 inch forward of the original position
per Van?s instructions.
Here is the problem:
Laying on the plane, the plexi fits well except two spots approximately 9?
to one foot in front of the roll bar. The Plexiglas is pulled away from
the fuselage on the left side 1". The right side is similar but with a
0.75" gap. The way these gaps appear presently, there is no way to glass
the front windshield in without a big bulge looking ugly! If I put
pressure on these areas, the Plexiglas pulls away from the rear of the
canopy. Presently, I see no way to eliminate these two gaps. Much
pressure is needed to push these in. (The canopy fits nice around the roll
bar, the front of the fuselage, and the rear canopy portion. Not many gaps
elsewhere. Can anyone help?
Another thought I had was to drill some initial holes in the top of the
roll bar first. This would fix the canopy in place. Then I would cut the
canopy in half. This way I could stretch the front portion around to the
side possibly eliminating these bulges, then drill the rest of the front
canopy portion to the roll bar. I would then have to trim the front
portion a little on the lower edges to allow the rear portion of the canopy
to slide up closer. I would then drill the rear canopy section to the rear
roll bar using shims to align it up with the windscreen.
What do you think, any other suggestions before I try to ruin the plexi??!!
I hope someone can help.
Thanks!

Thanks to everyone for the responses. All the referrals were for

Subject: | Left wing spar jig alignment holes |
I am building RV6 left wing and yes, I am stupid and didn't look
before drilling.
I searched the archives and couldn't find any info on this problem,
but I seem to remember it being discussed some time ago, maybe I
didn't use the right search words.
I sent this same question to Van's support people.
While drilling the jig alignment hole in the rear spar at 2.33" from
the top of the spar per the plans and 99" from the outboard end per
Hovan's instructions, the drill went through the edge of the spar
doubler (about 4/5 of the 1/8" hole is in the doubler). It is about
3" from the doubler plate, slightly after where the doubler bar starts
to taper.
My questions are:
1) Can I remove the doubler and cut away the material around the hole
to make a smooth transition, or would this weaken it too much? Should
I just order another doubler bar?
2) I know in the drawing that they say that the Y dimension is not
critical, but why isn't it centered (width wise) on the rear spar?
3) Should the bottom flange of the rear spar exactly line up with the
bottom edge of the front spar? I am at work and can't remember
whether the wing is exactly flat bottomed or not.
4) Is the pre-punched wing kit changed, did I mess up somewhere else,
or have other people had this problem following Hovan's instructions?

[snip!]
Once you split the canopy, everything changes. Just get the canopy
aligned as best you can, and take the plunge. Hopefully you didn't cut
too much off the bottom of the windscreen already. The way it wants to
lie on the fwd top skin will change a surprising amount once you have
made this cut. But even if you did take too much off, once the cut is
made you can just tip the fwd edge of the windscreen down, closing the
gap, and trim a "wedge" off the aft edge. Adjusting the angle of the
windscreen a bit won't change the appearance noticably.
How do I know this? Because I did all of the above.

Subject: | Re: Red/Orange Paint on Navy Jets |
I am curious as to why Navy jets have red/orange paint on the flaps and other
movable parts. You can see the paint when the flaps are down, but can not
see them when they are up. I like the way this looks, and I am thinking
about doing it for my RV? For those that think they need flap indicator
devices, this could be one technique. However, for many Navy AC, the pilot
can not see the flaps either up or down.
Any smart Naval Aviators, or other knowledgable people out there that can
explain the Navy's rationale.

Gary, my Earl's oil cooler , about 4 inches by 5 inches, is mounted in
the baffeling just inside the cowling inlet. We waited for 58 minutes to
leave Oshkosh on Saturday morning and the oil temperature never got over
140 degrees F. I have been unable to get the temperature over 170
degrees, even on 90 degree days at high power settings. Last winter, I
had it taped over completely to get the temperature to 140. Other than
the firesleeve on the gas lines and a shrould around the gasculator, I
also have a curved shield clamped to the exhaust pipe to keep radiant
energy from hitting the gas lines, carburator, and fuel pump. I have ran
auto gas all summer with no problems.

Hi Ray,
I have a printing shop for 25 years now. For 15 or more of those
years I have used PVC 1" for my air. Its ran all over my shop . To both

Just be sure to use the purple "primer" before the cement. The

fwiw, I put my air lines in and used 1" and 3/4 " sched 40 PVC. Why?
Because the local city building codes OK it for industrial use. I had
noticed that two welding shops, two tire shops, and a radiator repair shop
had it installed. I was about to pop for copper tubing along with black
iron, but having seen the PVC, I checked with the city code enforcer. It is
OK by the city code. Does that make it OK as for safety? I don't know. But
the locals bitch like hell because the city used some big cities codes for
our town, and they all say that the codes are too demanding.
Mine have been in since 1991, in TX weather in an unheated building where it
does get hot in the summer and cold (ignore that if you live up yonder!) in
the winter.
I take it from a discussion on the list about a year ago regarding PVC that
it is going to blow up and shatter me to pieces one of these days. But I'm
in the country where it will not hurt anyone else. Ce la vie!

It's not been that long since I finished my slider canopy, and in my
opinion your plan is exactly right. I think you'll be amazed at how
much better the canopy fits once you cut it in half.
One caution: be sure to leave enough edge distance between the roll
bar and the cut line. Later, if needed, you can always move the rear
portion of the canopy forward on the frame and trim as necessary to
achieve good edge distance on the rear canopy (slider) portion.
Good Luck!

Rich, this is normal. What worked for me was to mark the cut line with
the canopy as near to the position as you can get it. Once the canopy
is cut apart (done on the airplane) the front windshield just relaxed
right into place. A little minor trimming on the front edge and sanding
a slight wedge off the rear lower cut line and it fit great. Don't
force it, cut it to relieve the molded in stresses first.

There can be some air pockets under the gel coat but they are usually easy
to detect and can be filled later. I wouldn't take the gel coat off, just
sand and prime & paint. You'll save a lot of time by not sanding the gel
coat off, stay healthier and keep your shop cleaner. I believe there might
be some UV protection afforded by the gel coat but probably the main reason
it is used is for a parting agent. BTW, I think the gel coat dust is really
nasty. Be sure to wear a mask. You should remove the gelcoat when bonding
fiberglass such as the installation of the cowl scoop. Layups done on
gelcoat will not bond as well.

Never heard of anyone worrying about this. If you do prime the fiberglass
and let the part set, you'll have to sand and clean the part later to get
good adhesion of your finish coat.

I found a need for the small diameter die and the flat sided version as
well. A few of my HS rib rivets ended up rather tight against the rib

Regarding PVC piping, I had an experience that wasn't too pleasant. It

I had no trouble doing this with just me and the driver. We carried the
long box (with spars, control tubes, and fuselage longerons) off the truck
with no problem. The box with the skins is more awkward, but with the help
of a 2-wheel hand cart not a problem. Both boxes are heavy though, and if
you have back problems or other reasons to avoid heavy lifting you might
want another set of hands.

Brian--
The wing kit is crated in one 4' x 8' plywood crate and one long (15')
skinny crate. Both are pretty heavy, but manageable by two guys.
Unfortunately, when mine arrived, I wasn't home and the delivery guy
tried to carry them both to the basement by himself. He banged up
several walls, baseboards, doorways and the hardwood floor. But, since
he "wasn't supposed to put it anywhere but off the truck," and he helped
only with my wife's pleading, we couldn't file a complaint.
So, be present when it's delivered, preferably with a strong friend, and
NEVER put your wife in charge of handling the delivery!
Good luck!

I mounted the longerons on the jig before I made my modifications to F-605.
I moved the seat back brace back 1-1/2 inches. I think I had to angle the
ends of the brace but I don't remember shortening it since this would also
affect the rest of F-605.

I did the calculations with the 1-1/2 inch setback and believe the difference
was about 1/16 of an inch. You can adjust where you drill the holes to
accommodate this.

This change, like almost any change, ripples a bit. In particular, you
will have to lengthen the arm rest and shorten the rib in the baggage

Subject: | General comments on PVC for compressed air |
When the first question about installing an air system was posted by
Lothar Klingmuller, it never entered my mind to consider PVC, or any
other non-metallic option other than rubber hose, because I had never
seen it used. Granted, PVC would never suffice for HP applications,
but I think think that this is one of those issues that boils down to
acceptable risk.
Remember that PVC fails one way, catastrophically. It is brittle and
it snaps - you will never see it "bulge" or give a warning that it is
about to fail. In contrast, ductile materials like iron and copper
deform before they fail. As an example, the wing spar on your RV will
permanently bend long before it snaps if you exceed its G-rating. A
"plastic" (I'm not talking FRP) wing spar would simply bend and then
snap without any warning. Moreover, the failure in metals is going to
be characterized by a small crack which may not even propagate. The
violence of PVC pipe failure is exacerbated by the fact that air is a
compressible fluid. When a leak occurs in a water pipe, the pressure
in the immediate vicinity of the leak is ZERO as the "pressure" is
turned into "velocity". With a compressed gas the pressure drops as a
function of expansion (remember that water does not expand). This
means that the failed area continues to be stressed after the break
until the pressure in the pipe drops to a certain level, often
resulting a propogating failure (shattering). This likely reason that
someone pointed out the "no air" restriction printed on the PVC pipe
he encountered.
What does all this mean? You may never have a problem with a PVC air
system as long as you never exceed the design pressure limits and the
system is not subject to significant levels of shock, vibration, or
stress. Remember, PVC is BRITTLE, just like glass which,
incidentally, also has a high yield stress. As someone from Texas
said about this subject, "You pays your money and you takes your
chances." Just beware of the hazard. Code requirements are usually
written in blood, regardless of whether or not they have been adopted
by your local county.

Greg,
I haven't gotten serious about a possible canopy coating yet; I'm still
working to finish my wings while my fuselage waits in storage. I still
intend to pursue the idea. Problem number one is light transmission. I
plan to measure it through the existing canopy before applying any gold
and hard coat. It will be several weeks before I can address this
issue.
Kevin Shelton's remarks about GPS reception were very interesting. I
had never thought of the possibility that reception might be inhibited
by the gold coating. If your antennae are external to the cockpit (as
mine will be, I think), it shouldn't be a problem, but it's something
else to think about. I guess it depends on where one lives (e.g.,
Seattle vs. Phoenix) how important gold coating is.
It would be helpful if you let us know what you find out if you contact
Aero Sound Shield.
Thanks, and good luck with your canopy.

The major focus in this whole debate has been on the issue of
resettability. My concern is more with having a visual indication of
which circuit had a problem and whether the breaker popped and took care
of it.
For example, say I'm flying at night, and my panel lights go out. "Oh
darn!" I say, and point my flashlight (of course I have it handy) at
the CB panel. Instantly I see the breaker popped and know that:
a) Whatever the problem was, it was isolated to that one circuit.
b) Whatever else was on that circuit is also out.
c) The breaker took care of it so I don't have to worry about that smoke
smell.
It took me 1 second to determine all of this and now I can just get back

Yes you can get distracted with trying to reset a breaker, but I think
the bigger danger is getting distracted wondering just what is wrong and
what else might be wrong or be getting ready to go wrong. I think this
simple device can do a lot to minimize such distractions.

Most people put too many things on one breaker because they're
expensive and/or they've run out of panel space. With multiple
slot fuseholders, protected circuits are $2 each and I encourage
people to design in 10-25% spare slots for future expansion to
avoid doubling up later. In order to meet that spares requirement,
I'll often double up a couple convenience items like a hobbs meter
and dome light . . .

The fuse never fails to work.

But suppose the breaker had not opened, did the bulb burn out? Dimmer
pot broken? Wire loose . . . what is the value of knowing why something
has quit? Your first indication that something is wrong is when
the thing ceased to behave as expected. At that point, I'll suggest
it's more helpful to shift to Plan B (if needed) for that piece of
equipment and fly on.

If it's one fuse per system then one failure doesn't cascade through
to any other system. This is the beauty of thoughtful, failure tolerant
design. All of the uncertainties you suffer flying contemporary
spam cans can and should go away.

All good responses from Bob (as I expected). That's what I get
for trying to go head-to-head with the expert.
I still think a visual indication of a failed circuit can be helpful,
even if it doesn't cover all the bases, which was the main point I was
trying to make. But I guess I have to admit that if you look at it from
the standpoint of developing a system that is much more robust in the
first place (through the use of a greater number of separate circuits
fuses which are more reliable), then it will tend to diminish the
usefulness of such diagnostic aids.
Good discussion, I'm glad Bob started it even though I am trailing

Ken,
I would first be sure that this is what you want to do. Most tall people
have a lot of their height in their legs. I am 6' 4" and have no problem
with head room in the standard setup even with nice thick cushions
(courtesy of Cleveland Tools). At least another 1.5" could be gained with
thinner cushions. The mod I made after seeing it in several RVs was to
raise the rudder pedals by about 1" plus put them forward .75". This gives
more leg room for pedal use and the higher pedals allow your feet forward
underneath them in cruise.

Subject: | Re: PVC for compressed air |
Gentlemen,
We have used schedule 80 PVC for our shop air lines for many years at
100PSI. It is much easier to install than iron, as one might imagine,
and the schedule 80 pipe, which costs a bit more than schedule 40 is
very tough and rated for over 250PSI. We transition to iron for the
last few feet to any air-chucks, and anchor the iron pipe securely.
There are no warnings printed on the pipes regarding use for air
systems.
Our next door neighbor had a PVC air line explode in their shop and it
caused minor injuries to some employees. I am sure that they had not
used schedule 80, I believe that it was schedule 40.
If I were installing a PVC air system, I would use schedule 80. The
cost difference (over schedule 40) would not that great in a small shop,
and it is A LOT easier to install than iron.

You really need to establish the best position for the front part of the
canopy and mark a cut line along the rear of the bar. Once you cut it, it
will lay down much better, but you may still have to use some shims if your
bar is as badly shaped as mine was.
Then you will need to set up the rear part and determine how much of a wedge
you will need to cut from each side (wide at bottom, thin at top) to
compensate for the raising of the bar, considering that the rear needs to be
in the normal lower position. I had to have additional height welded onto my
roller brackets too.
Just take your time and proceed slowly.

Greetings fellow RV'ers,
The purpose of this message is to start a thread for our/my education on props.
This list is an incredible source of information and expertise/expierence. I
would appreciate sticking to the subject and not straying off into the
alternative power thread.
I am planning at this point to install a Mazda engine in my RV-6A. My question
arises around what is the best prop speed (RPM) to use. I have a choice of
speed reduction ratios and engine configurations to get my engine output at
180 horse power at whatever prop rpm. Here's the questions:
1. Is maximum prop RPM really gated by keeping tip speeds under supersonic?
Why?
2. Wouldn,t a prop turning at 2000 RPM (or slower) be more effiecent?
3. Is a 3 or 4 blade prop with a huge chord (like on c-130's) better than a
skinny 2 blade, and if so why are we not using them in G.A.?
4. Does anyone make props for slower turning engines?
5. A faster prop should create more drag robbing effective engine power. True?
6. What about these racing props turning 4000 plus RPM I've heard about?
I know, lots of questions but I need the education.
Thanks for the bandwidth,

from Shell noted in the Sept Flying magazine that 170 oil temp for one hour
minimum time would boil the moisture out of the oil system but that 180 was desirable
for a minimum. He advised double checking that 180 on the gage was an accurate
reading.
I have read several postings about super efficient oil coolers yielding super
low oil
temperatures. Shouldn't these coolers be blanked off to yield 180 oil temp?

Ok, on the props.. I'm just a 16 year old airport kid... but I know my
fair share
>1. Is maximum prop RPM really gated by keeping tip speeds under supersonic?
Why?
This is because at supersonic speeds, the prop tips are losing efficiency
due to the shock waves created as the prop exceeds the speed of sound.
>2. Wouldn't a prop turning at 2000 RPM (or slower) be more effiecent?
Yes. -- slower is better..

No, a one blade prop in theory is the best.. but then we have
problems with assymetrical thrust.. imbalances and such so 2 is the minimum..
each bblade has to travel through the turbulence created by the other
blade(s) and therefore with increasing numbers of blades, efficiency
decreases. 3 and 4 blade props are manily used when an issue susch as prop
clearance arises.. Amagine the -130 with 2 blade props..
>5. A faster prop should create more drag robbing effective engine power.
True?
> Can't really help ya here.. anyone else??
>6. What about these racing props turning 4000 plus RPM I've heard about?
I work with an Ex-racer from formula one class.. we're buildiing a
cassutt now, and I notice they are MUCH shorter.. the tips are not moving
much faster than the hub, so the supersonic problem isnt an issue..
I know that in some regards I may be wrong, but this is the best
that I understand things and I hope I was of help.

If I understand what you are asking correctly, I think you are fine having

Subject: | Buying used Lycomings |
First of all, thanks to those of you who responded with advice about attending
the Avery metal working school. Think I'll go to it soon, sounds like a good
source of info.
I am planning to start building an RV6A early this spring, if not sooner. I am
collecting tools and reading everything I can get my hands on. I really would
like to buy an engine before anything else, because this is the most expensive
item for the plane. I am trying to find a used engine that isn't too much. If
I had to buy a brand new one, I don't think I could afford to build the plane,
so I'm trying to take care of that first. My questions about Lycomings are in
3 areas:
1) I see ads for engines like O320-E2D, O320-T10-540,O320B1A, O360-F1A6,
O360-E1A6D, etc. What do all these numbers mean? I see ads with every
suffix imaginable! I really prefer the 180hp O360, but how do you know what
you're getting with last four or five digits? Is there a Lycoming
spotter's guide or part # list to carry to the aircraft salvage
yards?
2) Also in the ads, are some terms which I really don't understand either?
Runout, SMOH, SOH, and Prop strike
3) What is considered really high hours on a Lycoming?
Should I find one "with" complete logs or does it really matter?
I hope these types of questions aren't too basic or make me appear any newer
to this than I am, but I can't seem to find any good info. on the subject.
Maybe there are a few other poeple out there with the same, or better,
questions.

Peter,
I like it: Skinner Floppy. Sounds real "high tech". Mind if I use that
in my "advertising"?
I laid up a fairing today which reminded me that I agree with you. I
eally hate working with epoxy. May try vinyl ester resin on the next one.
It's much easier to work with.
I've had five orders, so far. If I get too many more, I think I'll raise
the price. It takes me about 1.75 hours to get all of the stuff out, cut
cloth and lay it up and then my shop smells bad for two days.
I enjoy helping fellow builders out but if I have to make too many, it
will cut into my building time (and trout fishing, next spring.)

Bob

This is a good reason for NOT buying the engine first.
When building an RV, the engine is one of the last things you attach.
So, you could tie your money up in an engine that's parked in the corner
of your garage for 5 years, or you could have it in the bank earning a
useful amount of interest. Or you could spend that money now on buying
kit parts and tools, and save up for the engine whilst you are building.
Also, unless it's carefully preserved, it's not good for an engine to
sit idle for long periods.

You could also consider an auto-conversion (eg Mazda 13B rotary or Chevy
Vortec V6). By all accounts it takes more time to get them flying, but
they're cheaper to buy and cheaper to overhaul.

Runout... engine has reached the end of it's life (nominally 2000 hours)
and needs an overhaul.
SMOH... Since Major OverHaul.
SOH... Since OverHaul
Prop strike -- the Prop has hit the ground/a fence/whatever. Because
it's attached directly to the crankshaft, this will probably involve
overhauling the engine.
> 3) What is considered really high hours on a Lycoming?
2000hrs is the normal TBO (Time Before Overhaul). It'll probably run OK
for a bit more than that (maybe as much as 3000hrs??? if it's looked
after and you're lucky, and feel like pushing that luck. It's also
common for an engine to NOT last all the way to TBO, especially if it's
only run occasionally.
> Should I find one "with" complete logs or does it really matter?
If an engine doesn't have logs you don't know its history. Because no
logs drops the value of an engine a lot, their absence possibly means
that someone somewhere is hiding something bad. Maybe *real* bad. Get
the engine real cheap, since you'll probably need to overhaul it. Engine
overhauls are very expensive.

Nah... they're good questions. It's knowledge that you (and other RV
builders) will eventually need. Fire ahead. You could also ask on

I am curious as to why Navy jets have red/orange paint on the flaps and other
movable parts. You can see the paint when the flaps are down, but can not
see them when they are up.
I very well may be wrong, because I was in a Marine Corps squadron not a Navy.
But, I think they do that for accident studies. A lot of the time there are
flightline or carrier deck cameras rolling all the time. If a guy comes in and
crashes, they can review the tapes to analyze control surfaces, etc.
Flightline maintenance may even be observing these as well. I worked avionics
on F18s and our Marine birds didn't have these colors, we were ground based,
so it must be a carrier thing. Hope this idea isn't too far off.

Subject: | Re: PVC for compressed air |
Just checked at the local PVC pipe supply outlet. The next step up from
ordinary PVC is "Flow Guard Gold", a little more expensive, but printed on
the side it says, "100 PSI @ 180 degrees" and "400 PSI at 73degrees". 400
PSI is about 3 times the pressure rating my compressor has. Some regular
PVC also showed 2 strength ratings based on 73 degrees and a hotter temp
with different high temp ratings varying with the pipe manufacturer. So
perhaps if you don't run it thru hot areas you will be OK. Flow Guard is
supposed to stretch before bursting. Must use Flow Guard elbows,
connectors, etc. More speculation: If PVC is brittle, maybe that is why
some PVC says not for air--some air tools, such as impact hammers might put
a lot of vibration in the system. Using Flow Guard with secured metal
fittings sounds like a good way to go.
I used ordinary PVC for awhile & it did burst--turned out that one small
section of pipe was not schedule 40, but a lower strength rating & of
course, that's where it broke. It was exciting but no damage or injuries.
I would go with Flow Guard today.

Anthony,
Lycoming nomenclature can be found on the web. I believe Hovan's RV
homepage has a link to such data. At any rate, it's out there
somewhere..I've seen it!
SOH=Since overhaul
SMOH=since MAJOR overhaul
Prop Strike=BAD NEWS!! The prop hit the ground when the engine was
running..can mean a bent crank, busted valves, etc.
"High" hours...depends on many things. Most can go 1800 to 2000 hours
before an overhaul..with religious oil changes and proper cooling.
A "runout" engine is one in need of overhaul..meaning that the
compression of each cylinder is no longer sufficient to generate rated
power. It also entails a thorough inspection of all the accessories,
alternator, ignition harness, plugs, mags, etc.
I'm planning on a mid-time (1000 hours or so) Lycoming IO-360 for my
RV-8...and will overhaul it myself when the time comes. I think I can
find one, with a fixed pitch prop for around 12-14K...(knock on wood).
So, for now..don't be overly concerned about it...build the airframe
first! It's all a matter of completing one small task at a time..then,
before you now it...you have an airplane!

You may want to reconsider that plan. Building an RV takes quite a
bit of time (at least 18 months for my QB, longer for the standard RV
aircraft). If you buy an engine up front it will be sitting there
deteriorating (cylinder rusting for example) as you build the rest of
the plane. Even the factory preservative offered with the brand new
Lycoming is only warranteed for 6 months.

I tried both and found that the one that Aircraft Spruce sells, being
made from aluminum, is too flexible to do a decent job on more than the
smallest, thinnest parts. I sent it back and got one from ATS, which
is made from STEEL, and is beefier all around. A much better value

gave me the phone numbers of local vendors that sell the tape. The tape
comes in 72 yard rolls for about $60.

Glen,
I made a landing light with four-way adjustment out of aluminum.
It only took 6 or 8 hours and uses the standard sealed automotive hi-lo
beam halogen light bulb. i also made the plexiglass (acrylic) cover for
the light. it worked out real well. The reason I made my own was: 1.
I wanted the sealed automotive bulb, 2. I didn't think the one sold
through Van's seemed very substantial (light output or size). My
judgement was made looking at one purchased by a fellow RV-8 builder.
Just some thoughts... If you would like, I can send you some
pictures of my installation. Let me know.

Royce,
.... I made up an internal 0.032 plate with floating nutplates on
it. There have been some reports of the single layer rear bulkhead of the
-6A being a little weak, and having failures/distortion at the tiedown
bracket attachment. This internal plate also acts as a doubler as well as
removing the need for finding a midget with triple jointed arms to tighten
the nuts ...:^) The plate can be inserted through the large hole under the
HS and thne moved aft into it's final position.
Not an original idea ... I've seen others built this way ... and
I'm sure I'll be much happier at final assembly time.

Through one of the inspection holes you placed at the aft end of your
fuselage. I made mine as big as possible but will still have to get
some help from someone with small hands to install the bolts. I plan on
installing the bolt with threads aft so I can easily inspect the
nut/thread relationship so the helper with small hands will have to
install the bolt and hold the wrench on the head while I torque the nut
with a washer under it.

Personal injury aside, how much money is saved if the pipe lets go and sends a
piece
through a just completed wing panel or causes a huge dent??? It always amazes me
how we

It strikes me that based on the examples and ancedotes, there are a few
systems where it is appropriate for breakers instead of fuses. I look at
these messages and I keep in mind Bob's point that circuit protection is to
protect the wire, not the device, and it's usually the device that fails.
Most electronic devices, when they fail, fail for good. One moment of the
wrong voltage across a chip and poof, it lets out all the magic smoke that
makes it work. Being able to reset won't help. However there are some
devices, like electric flap and gear motors which can fail temporarily, by
overheating, but be okay once they cool down. Devices like this should have
breakers because successfully resetting them is a possibility, and can be
crucial to flight safety.
(I was also stuck once in a spam can where the landing light would run for
about 5 minutes before popping the breaker. Resetability was kinda crucial
there.)

Well, the ability to exceed VNE in level cruise is generally what we would

The rebuttal to this is: " Why did the landing light breaker trip? Why did
the flap motor overheat? The result of poor design or design error is the
answer. In a properly designed system should not experience these nuisance
trips."
I dont necessarily agree with the above. In a perfect world everything
would be properly designed the first time around, breakers/fuses would only
trip due to a genuine problem, and the pilot would never need to reset
because he would be assured that the trip was caused by real failure.
Unfortunately, design errors do occur, as do nuisance trips, even in the
homebuilt community. Of course when an inaccessable fuse blows in flight
because the flap motor overheated, thats not a nuisance trip, thats a real
failure because there is nothing the pilot can do about it.

Try 1 800 use enco. They carry a line of larger metal brakes at a reasonable
cost. Also there should be a good availabily in the used equipment market.
Check with your local machine dealers. The 48'" brake is large enough for
them to carry. Expect to pay $350 and up for 48" and larger. Watch the

. . . but the pilot CAN do something about it. Thats the glowing
difference between our airplanes and spam-cans. With the
A-36, what you see is what you get. With an RV-6 you can do whatever
is necessary before the airplane is ever flown to (1) eliminate the
potential for problems or (2) make the problems no-sweat events.
That airplane in your shop lives in as close to a perfect world
as any airplane ever has . . .

No doubt people have suffered experiences where resetting the breaker was
useful . . . but ask yourself if the system involved was adequately
designed? One reader told of a case where a mechanical interference
of the partially deployed manual extension handle on a Bonanza's
gear system trashed the gizmo where it was no longer useful and repeated
resets of the breaker managed to put the gear down in spite of the damage.
I'm very familiar with the gear extension system on the Bonanza having
been both A-36 pilot and supplier of gear system components to Beech. The
system may have passed muster in 1950 but we can do much better than
that now. That system has potential single points of failure for both
electric and manual extension systems . . . and the pilot who wrote about
this case has discovered one of them. NOW . . . from the FAA's point of
view, the number of cases for this set of circumstances to occur may not
warrant an AD or even pressure to redesign the system.
We're not building certified Bonanzas, our airplanes should NOT suffer
the problems that were carried over from a 1950's design philosophy.
It's ESSENTIAL that all these stories be told, listened to and considered,
NOT to insure availability of the same band-aids, crowbars, and bubblegum -
but to DESIGN those kinds of features out of our current endeavors.
Oh yeah, you can't land without a landing light? Suppose the bulb was
burned out? As pilots we are part of the flight system hardware. If
we're comfortable with night landings sans lights on airplane, so be
it. If we're not . . . . there had better be TWO of them!

Don,
The RV-8 is more expensive than the RV-4. You will have to make that
decision yourself. However, the RV-8 kit provides much more value for
the dollar. I have kept in touch with several friends building RV-8s,
and the kit improvements they report are well worth the price.
A strict comparison of the two airplanes convinces me that the RV-8 is
the better airplane. After all, it incorporates some twenty years of
experience in its design. Yes, the RV-4 is prettier, but the RV-8 has
been growing on me. The redesign of the production prototype, raising
the instrument panel slightly and enlarging the vertical stabilizer, does
much to improve the lines of the airplane. My next project will be the
RV-8.

-Jeremy King
Well Jeremy, I agree with you 97.374%. You mentioned how one prop blade
passes through the other's turbulence. With my experience (Limited, I am
again only 16, but then again....two 16 year old heads make up one 32 year
old's!) I believe that in normal cruising flight, a propellor's blades are
turning fast enough that as one blade passes through an area, the forward
motion of the plane is enough that when the next blade comes around, you are
a couple feet ahead of the turbulence caused by the first blade. This would
explain why all you pilots that try to pop helium balloons with your prop
(Who me!?!) don't get the balloon unless you squeeze it between the prop and
the cowl.
Also, the second number of a prop's size is the distance it travels in a
perfect fluid. So, let's say I have a 72x65 prop. It will travel 65 inches
per one revolution. Well, on a 2 blade prop, that will be......(E-6B is a
spinnin') 32.5 inches in forward motion till the next blade passes. And on a
3 blade prop, that would be 21.6 inches. Now, I know I haven't accounted for
air being a non-perfect fluid, but I hope this proves my theory close enough.
I still have algebra 2 homework to do, so I don't want to rack my brains too
hard :-)

>1. Is maximum prop RPM really gated by keeping tip speeds under supersonic?
> Why?
I am not a prop expert, but I do have some theoretical knowledge.
If the prop tips are supersonic, or close to supersonic, the shock
waves cause a huge amount of drag. This reduces prop efficiency, and
hence the amount of thrust you get is reduced.

>2. Wouldn,t a prop turning at 2000 RPM (or slower) be more effiecent?

It depends. A slow turning prop either needs more blades, or greater
diameter to handle the same amount of horsepower. Extra blades hurt
efficiency because there is a greater tendency for each blade to be
operating in the wake of another blade. Larger diameter helps
efficiency at low speed, but hurts it at high speed. A large
diameter, two-bladed prop should improve take-off and climb
performance, but would probably hurt cruise performance.

Basically you need a certain amount of blade area to handle a given
amount of horsepower. The C-130 has 3 or 4 blade props with wide
chords because it has 4,000 hp or more per engine. The only G.A.
guys that use such props are the air racers (check out Rare Bear - it
has 3 Electra blades).
>
>4. Does anyone make props for slower turning engines?

Not necessarily. The blades would be shorter, so that would help.
The extra rpm hurts. The sum of the two could be good or bad.
>6. What about these racing props turning 4000 plus RPM I've heard about?
>
The racing guys turn up 4000 rpm because they get more horsepower
that way. The prop efficiency is probably hurt, but the extra
horsepower more than makes up for it. They might be better off with
a gearbox and a slightly slower, larger prop. But the rules don't
allow that.
>
>Pat Kirkpatrick
You might be better off with a slower, larger prop - if you could get
a well designed one. You would probably need to get it custom made.
But, the maker would not be able to take advantage of all his
experience with "normal" size props - this would likely cause the
prop efficiency to be less than optimum. Thus even if there was a
theoretical advantage to a large, slow prop (and it is not clear
whether there is or not), you probably would not be able to realize
this advantage without a lot of experimentation with the prop maker.
My advice - if you want to fly, chose a gearbox that gives a max rpm
of 2,800. This will let you find a cheap, good quality, high
efficiency prop. If you want to tinker and spend money on props,
then get a couple of different gear boxes, and start experimenting.
Note that a slower turning prop will need to be larger diameter, and
you will probably need longer landing gear legs (= more drag).

Glen,
I think you are asking about the Bob Olds landing light kit. It uses two
130 watt halogen automotive headlights, one in each outboard leading
edge. The high-beam/low-beam feature allows for both landing and taxi
lights. I have seen them in operation, and they are impressive. I have
them in my RV-4. Installation was fairly straightforward.

Jerry has a reputation for making very high guality fiberglass parts. He
also has a reputation for being VERY SLOW to deliver.
I ordered a set of gear leg fairings (and sent him a check) on May 18, 1996
(That's right: 1996). I still don't have them. I have called Jerry
monthly for the past year with no results. Since July, I've been telling

You are assuming that the effect of a propeller blade moving through the
air is limited strictly to the flight path of the blade. 'Taint so.
Find a photo of two like airplanes during air-to-air refueling (two
KC-10s, for instance). The receiver is traveling below the flight path
of the tanker. Both airplanes are traveling at the same speed, yet the
receiver is always at a significantly higher angle of attack than the
tanker. The receiver's wing is operating in the downwash created by the
tanker.
By the way, congratulations on your Sophisticated Lady. It is a great
glider. But what the dickens is a Northstar?

These little halogen lights are incredible lumen makers and almost weightless so
why not use one of them.. My wife read something about how these little lamps
put oour like they do because they run much hotter and have been implicated in
many home fires. Hmmm. Maybe sealing them up is a good idea in an airplane.

Certainly a motor could overheat, and a breaker might be useful there.
However, if a flap motor or landing light is truly a flight critical
system, then you had better have two of them, on completely separate
circuits. Otherwise, what do you do if the motor or light fails?
I suspect that most of us could land without flaps, so I wouldn't
call a flap motor a critical system. Also, any of us that only have
one landing light, or two lights but on the same circuit, had better
practice lights out landings once in a while. Its not hard on a
lighted runway (at least with a tricycle gear).

Download IE 4.0 with Outlook Express mail. Then you can click on the

can save it right to your RV folder on your favorites (bookmark) lists. I
have not seen the latest version of Netscape, but I think IE is great!
Some other things that are neat. In Outlook Express you can use inbox
assistant to send all of your RV-list msgs to your RV-list folder. This way
you can read your RV mail when you have time and deal with the other stuff
imeadiately ( or you can ignore your work related mail and read the RV list
first). You can also ckick on the subject header and have your mail
imeadiately sorted by the subject (thread). I think Microsoft has really

It's hard to answer your question without knowing what platform
and browser you're using (though you did mention Netscape). But
here are some possibilities.
(1) If you use your browser to read your email, the browser will
automatically convert the URL for the web page into a link. For
example, if someone writes "see my home page at
http://www.somewhere.com/" the 'http://www.somewhere.com/' part of
the message will become an active link to the web site. You can
just select it, jump to the site, and then select "Add to Bookmarks"
from the Bookmarks menu.
(2) Cut and past. Most platforms (Mac, Unix, or--ugh--Windows NT/95)
support cutting and pasting in one form or another. You can highlight
the text in the email, copy it, then paste it into the Location field
on your browser (the place you would normally type it).
(3) If you're on Unix (yeah), you can use a nifty program called
Hypermail to convert your email inbasket to a web page on your own
computer. You can then view the web page, sorted either by thread,
subject, date, or author. URLs (web addresses) that people put in
their messages automatically become links (as in #1, above).
I use Hypermail on unix, together with a mail filter called Procmail.
Together, they automatically send my RV List messages into a special
file, and turn the file into an organized web site that I read with
Netscape. This is _much_ better than sorting through the messages
with an email program.
I haven't used some of the more sophisticated email programs, such as
Eudora or CC:Mail. I think some of them combine email and browser
capabilities. You might want to investigate them.

Sometimes redundant systems cause more problems then they solve. (e.g. higher
accident rate with twins). And sometimes you just can't have a redundant

Maybe not on an RV, but some aircraft have a lot of trouble doing a go-around
with the flaps down.

I'm assuming that you are using NetScape for both email and browsing.
If the posted homepage is actually a link (highlighted), you can click
on it to go there, add the bookmark (Ctrl-D, or Bookmark menu/Add
bookmark), switch back to email, and continue reading messages. If it
isn't a link, or if you don't want to wait for the page to display; you
can select the homepage reference by highlighting it with the mouse and
copying the text to the clipboard with the Copy command on the Edit menu
(or just type Ctrl-C). Then you can paste the text into your bookmark
file with the Paste command on the Edit menu (or type Ctrl-V). Just open
your bookmarks with a Ctrl-B from the Browser window (Bookmark menu, Go
to bookmarks); insert a new bookmark (Item menu, Insert bookmark); and
paste the text into the location field. You have a name and a
description available to you as well. This process is easier to do than
it is too describe, so don't let my long rambling directions throw you
off!!

Chris,
I put a 1x10 board in there and just laid down on that. I needed to
put a couple of notches near the aft end of the board so it wouldn't
bend the sides of an aft bulkhead. I know it looks scarry to do
this, but it worked for me (160 lbs).

Hi Chris,
I'm at exactly the same place you are. And I'm doing it the very easy
way.
I have the fuselage on a spit ( like bar-b-q style) I simply rotate it to
the exact position I need and just lean inside to do the work.
I use a one inch pipe flange (the flange you can bolt to the ceiling then
screw the pipe into) one at each end of the fuselage (well actually I use
two at the rear). At the front I weld an elbow in place to fashion the
handle.
I drilled a hole through the handle, then tru the plywood backboard in
several places to make it stay in any one position or it can free wheel
if needed.

Morning all,
In the builders supplement Vans mentions that it is sometimes beneficial to
lightly touch dimpled holes with a countersink cutter to clean them up. I
have found that when dimpling sheets .032 and thicker it makes a big
difference in the finished surface. All it does is square up the sides of
the dimple to match the rivet heads. Do just enough to remove the finish
on the sheet but be carefull and practice first. As your dimple dies get
older, or if you are not using the $38.00 dimple dies to begin with, this
technique really makes a difference.
Hope it helps.

Odds are against it but it only takes once. Will be going with all manual

If you want the best of safety with electric trim motors, do like the RJ 50

I write:
Following are selected quotes from the Product Data for Sherwin Williams
GBP 980 and its aerosol equivalent 988:
PRODUCT DESCRIPTION
GBP is a two component, chromate containing self etching primer/filler
designed to eliminate the metal conditioning step. Etches the surface of
bare metal substrates to provide excellent paint adhesion and corrosion
resistance.
TECHNICAL DATA
Salt spray resistance: Excellent (500 hrs)
Humidity resistance: Excellent (500 hrs)
SURFACE PREPARATION
Bare metal: solvent clean
SUITABLE SUBSTRATES
Steel
Aluminum
Fiberglass
OEM enamels
OEM lacquers
Cured body filler
NOTES
- Min dry film thickness of 1.0 mils is required for corrosion
protection.
- Do not use GBP on large pre-painted surfaces.
- Sealing of GBP before topcoating is recommended due to some minor
chromate pigment bleed under light colors (my note: 980 is olive drab,
988 aerosol is gray, so this may be less relavent to 988).
- Do not wet sand.
- Do not apply over MET-L-MATE or similar conversion coatings.
- Do not re-coat with Vinyl Wash Primer E2-G973,zinc chromate primer, or
two component polyester based primers.
Hope the above is helpful. I've just switched from Marhyde to SW 988.
The 988 is easier to apply a nice even coat due to the spray nozzle
which produces a nice even vertical stream. It also seems a little
thicker so it's less prone to run. It's a darker shade of gray too, so
it's easier to see on aluminum.

>Craig and Don: I agree with Craig that the RV-8 is a better buy. The performance
of the -4 and -8 in relation to HP is probably too near the same to swing
the decision either way. Appearance is subjective. What is not often mentioned
in such decisions is the mission the aircraft will be asked to perform. An
RV-4 with a light engine and prop will be a delight to operate in maneuvering
flight but will be less so for long cross country flight. My RV-4 with a passenger,
baggage and low fuel is more work to fly for long periods. Conversely,
with a heavy engine and prop, the long cross country will be more comfortable
but the maneuvering flight won't have the same charm. The RV-8 has the potential
to deal with these requirements because of its higher useful load and more
loading options. With the CG somewhat aft the -8 will do loops, immelmans,
split esses and the like with aplomb. When loaded for cross country it will
afford pitch stability the -4 cannot. Think hard about this one. It is why
I am bui

Regarding the polishing comment from another thread: It takes me about
100 man hours per year to keep the -4 moderately well polished. If you
don't want to do this, forget about keeping is shiny. If you do want
one to be shiny, consider painting the bottom only. The underside takes
an awful beating and at least in the humid regions is a real bear to

Thanks for staying with it. The matronics.com URL fell of the edge
of the world a few days ago and everybody's input to the list
was bounced or disappeared. There are still some funny things going
on as I've had to post one or two pieces twice to get them through
the pipe. Computers is wunderful!
Here's a case where I think complicating the system has good foundation
in pilot versus airplane ergonomics.
Pulling a breaker on trim runaway is too time consuming and there's
a lot of window for error. If your trim breaker is located in a whole
nest of other breakers, the possiblity of pulling the wrong one in
time of "tense pilot response" is great. Pulling the wrong one may
no have electrical consequences for flight for inadvertently shutting
down another system but it adds still more delays in perception and
resolution of multiple problems . . . all design and/or pilot induced.
In any case, pulling the breaker is far more time consuming than some
alternatives. During trim runaway, time is of the essence. The longer
you delay in effecting shutdown, the further out-of-trim the airplane
is going to be when the motor stops running . . . we need to shave
tens of milliseconds off of the perception-reaction-action time needed
to bring things under control.
I'm working on an article that suggests powerful electric trim systems
should require two switch actuations for operation . . . not unlike
requiring your starter current to also pass through the battery contactor.
You have a way to deal with a stuck starter contactor by shutting
of the battery master.
Suppose you had a stick grip with the usual coolie-hat trim button and
a second, "arm" button for all electric trims. The arm button would have
positive control over electrical power to all trim systems and would
have to be held closed at the same time you are commanding trim. The
advantage is that you hand is already on the control necessary to
disable the trim when the runaway happens. Even if the trim relay
stuck at the conclusion of your last trim operation (latent, unannunciated
failure) then as soon as you pressed the "arm" button, you'd get an un-
expected trim operation and your reaction to release the button is
a few hundred milliseconds away from successful trim shutdown . . . you
can't do it any faster any other way.
For airplanes with autopilots and powerful servos, the situation
is a bit different. Here we have mulitiple, electrically driven systems
with the ability to drive flight controls. The common wisdom here is
to fit the aircraft with an "autopilot disconnect" button on the wheel
or stick. When you think about it, the pilot's first reaction to
countering
an unexpected input from electrically powered flight controls is to grab
the stick to keep the dirty side down and the pointy end forward. It
stands to reason that all the controls necessary to corral the runaway
system should be on the stick or wheel too . . . the "autopilot disconnect"
or "master trim disconnect" button would have positive control over all
electrical devices connnected to flight controls.
When things are back under control, the pilot may elect to experiment a
bit to see if it was trim or autopilot that caused the upset and shut
down the offending system (perferably with panel mounted, clearly labeled
switches . . . not little black buttons hiding in a flock of other little
black buttons).
>. . . I know for a fact if the trim were all the way to one extreme you
>would have a hell of a time bringing the airplane back in one piece.
If this is true, has your trim system been fully evaluated for both
speed and travel limits? I have several builders I'm working with now
trying to get them to revise the mechanism that connects servos to tabs.
Trims in a mechanical limit on these airplanes produces a barely flyable
airplane.
This conversation goes right to the issue I raised a few weeks ago with
the Great Breaker Debate . . . we've commonly viewed and many of us have
been REQUIRED to compensate for POOR SYSTEM DESIGN by fiddling with
breakers.
IMHO, no matter what fails or how it fails in your airplane, your
reaction should be no worse than, "Oh fudge . . . is that thing
broke again! I think I'm gonna have to find a better part." My brothers
in the certified world would like to design airplanes with that
philosophy but are prevented by a host of regulatory and bureaucratic
walls and mountains. Unencumbered by such obstacles here in
amateur-built world, we're going to build the best airplanes that have
ever existed.

Bob,
I think you missed my point. You need to seperate the pilot from the
designer. Once the airplane is flying, with you at the controls, and a
failure occurs, you have to deal with it in real time as a pilot, not a
system designer.
I agree that as homebuilders we have every opportunity to design problems
out of our airplanes before they ever fly. In spite of our best efforts
design errors occur. You yourself described such an error earlier in this
thread (I believe it was in reference to an alternator field fuse which was
undersized, although I cant recall the details). If a system is under
engineered or improperly designed or constructed and is protected by an
inaccessible fuse, if/when that system fails in flight the pilot must live
without that system. Of course because that aircraft is a homebuilt, if/when
the pilot successfully lands that airplane he can re-engineer that system so
that hopefully that failure would not occur a second time.
I cant speak for you, or any of the other builders on this list, but I can
look back on the work that I have done on my RV to date and say that I am
not infallible. The potential for electrical system design errors in my
aircraft definitely exists but with help from others such as yourself I hope
to minimize those errors.

If you can't overpower the electric trim, it doesn't belong in the
airplane. I had a trim
runaway one time and it was not fun but not terribly dangerous.
Along the same lines, I was planning to install a navaid autopilot in my
plane but am having 2nd thoughts. If the autopilot were to "wig out" while
cruising 50mph above manuevering speed, It might make an awful mess before
I can recover. I wouldn't even want to think about such an event occuring
in IMC. I know that all A/Ps are clutch driven, so overpowering it should
not be a problem. It's just a matter of what might happen in the 4 or 5
seconds it takes to get a grip on things.
Opinions??

Then it's poor system design. For example, many people with two
engines on the light twins think they have redundant electrical
systems . . . when in fact, loss of a single battery contactor makes
use of both alternators a bit shakey if not impossible. Redundant
doesn't necessarily mean two of the same thing. I've submitted
an article for publication that does an alalysis on a pilot's
wing-and-a-prayer story. There were a number of problems with the
design of his electrical and gear system where unannunciated failures
could lurk. Further, his manual gear extension system was poorly
debugged.
I suggested in the article that the manual extension system should
be considered the "primary" extension system . . . the simple
system that should be expected to work EVERY time. The electrical
system was "secondary" and included only for pilot convenience.
I got my retract signoff in a Beech Sierra a few years back. I
LOVED the manual gear extension system in that airplane . . . open
a door in the floor at your feet, turn a valve and the gear falls
down and locks. You could blow open every hydraulic joint, smoke
every wire, lock up every motor in that airplane and guess what,
the wheels fall down and lock . . . . what a concept!

Back in the good ol days when Cessna was being praised for their
"barn door" flaps, the C-150 was unable to achieve level flight
at full gross with full flaps. It bit more than one student who
didn't know that a go-around maneuver took 50-100' of altitude. Once
you were below 50' AGL with 40 degrees of flaps, you were committed
to put wheels on the ground. Again (forgive me folks), let's not
put band-aids on poor designs by increasing pilot workload. If your
airplane won't climb on full flaps, then don't put down full flaps
until you are SURE that the comfortable arrival with the earth is
a done deal.

Rich,
You are correct, you can lightly dimple the .032 and
then countersink. By doing this you will have a stronger rivet because
you will have removed less material than by countersinking alone. Good

Two quick questions for those with more RV time than my initial 20
hours.
First, what is the power off best glide speed in an RV, particularly an
RV-6A? How would the actual glide angle at that speed compare to an
engine off condition as compared to an engine at near idle?
Second, regarding Vans Vne of 210 mph. should I regard this as true or
indicated airspeed. In other words, at my normal flying altitudes of
11,000 - 12,000' (high country of Colorado), approximately 180 mph
indictated equates to 210 true. At this altitude, should I consider the
180 indicated as my actual Vne?

Anyone who has built their own fiberglass gear leg fairings, or metal for

the Harmon Rockets will buy his fairings. I will use them on my second -6

pointed out the kinked, one piece, metal fairings on the yellow RV-8

Chris,
I laid boards and pillows and wrenched myself into place. I did it all
myself but if I were to do it again I would have someone on the outside
fitting the clecos and watching for any unwanted creep. I had to do mine
twice. I thought the skin was centered but after I had drilled it all, one
side didn't have enough edge distance. I couldn't see this from the inside
and because it was such a pain to crawl in and out, I didn't check this
enough. There is very little room for error as the skins are not oversized
at all.
To keep the bulkheads straight, many people attach plywood to them. Also,
be careful not to sinch the skins down to tight as this will cause the
bulkheads to bend and or cause small dents above the notches in the
bulkhead. Again, I was alone and used a ratcheted tiedown to keep the
skins tight....very easy to overtighten. The second time I just used lots
of duct tape.

With the QB you do every operation, even some that regular builders don't do.
You just don't do all of them ad nauseum.
Complete it yourself? You can do the following or hire it out legally:
Upholstery
Paint
Panel
Engine & prop get ready (install ?)
To me, QB just means I hired someone to do the repetitive work for $8 per hour.
Actually, building a fixture for the fuselage and starting it up still seems a

I also, went through the same thought process. I decided after speaking
with Ken from Van's on the following. I would make my final decision on
this after completing the regular tail build kit. If you just order the
tail kit, Van's will deduct $2000 from the quickbuild if you later
decide that is what you want to do. I just got my tail in. This is my
first aircraft building experience. I have had some involvement with
the EAA and have heard the stories of people taking 10 years or more to
finish the kit. There is even a guy here in the local area that has had
the engine hung for ten years and he still is not done.
Please don't mis-understand. I think that a lot of the fun is also in
the journey, but for me actually completing it and spending some time
flying it is an important part of the journey for me. If you proceed the
way I have described, in a sense you can get your big toe in the pool by
building the tail and then decide on the way you would like to go. Also
because so many before me no doubt a bunch more experienced, with more
free time and more enthusiasm(this is hard to believe) on their hands
than me have gone before and failed, I tend to lean toward being
conservative. If you proceed this way it is not $8000 difference, but
only $6000 difference. If Van's numbers are accurate and it takes 2100
hours for the normal kit and 1100 hours for the quickbuild, you save
about 1000 hours (multiplied by any factor you feel is reasonable). For
me, that 1000 hours will translate to a year very easily, unless I
totally give up other aspects of my life. I do have a full time job.
This year may mean the difference in between me finishing it or not.
I may opt not to go the quickbuild after building the tail, but at this
moment it seems most appealing to me.

Hi Ken:
I have experience only with a rudder from a Zenith Zodiac. I found out some

building mine in my garage, as hanger space is pretty impossible to come by.
If I do the quick build kit, I am forecasting about 800 hours or so, just
because I am pretty handy, and have about 30 hours of metal experience with
my Zodiac.
I too just ordered the info pack and video two days ago. Our situations are

through our building experiences together sometime. I plan on taking
delivery in December or January, and hope to have it completed by Oshkosh.
I am having a company called Aerotronics build my custom panel that I

There is **MORE** than enough work to be done to give you the "I built it
myself" feeling. Probably one of the fastest QB efforts is taking at least
18 months (elapsed time) of work. I **KNOW** it will take me years. Now
maybe most QB buyers simply have less time or less skill ... I do know
about others, but I would put myself in that category. The QB made it
POSSIBLE for me to make the decision to build. Without it I would NOT have.
But, if you have *plenty* of time and really enjoy drilling every hole and
pounding every rivet, then you may not like it. If you are short of time
(or like me, time **and** skill ;-} ) and have a few extra $$, I highly
recommend the QB.
I bought mine last year and at OSHKOSH this year noticed a continued
improvement in the already high quality.

- Don Corbitt, donc(at)analogia.com]
Corky Scott wrote:
In this month's "Sport Aviation", in the photo section reviewing some
of the aircraft and displays from this years Oshkosh fly-in, was a
photo of a scimitar shaped prop on the nose of a wingless fuselage. I
was intrigued by the color and shape of the blades. They were bright
yellow and had a PRONOUNCED scimitar shape. I knew from past readings
that scimitar shaped props were designed that way to allow them to flex
in flight and assume some of the characteristics of constant speed
blades; they are deliberately pitched to a cruise (coarse) type pitch
and flatten out at slow speeds to allow the engine to spin up and
develop more power. At higher speeds and reduced throttle, they unbend
back to the coarse pitch. Or at least that's the idea. This is not a
new concept, it was first used in World War I. In those days, the
shape of the blade and the type of wood they used was mostly guesswork.
One of the scimitar shapes I've seen (EAA's Experimenter a month ago)
actually had a swept forward shape. Bob Whittier, the author of the
very informative article did not think the forward swept prop was very
successfull.
The blurb on this new prop claimed that it was computer designed to
predictably flatten out at slow speed/high power situations and then
unbend to a coarse pitch at higher speeds for good cruise by the use of
computer design and modern composites and resins. I was intrigued, I
called the number and talked with QCS. I spoke for about half an hour
with an individual (sorry, I didn't write his name down and I'm not
sure so I'd rather not guess) who said his expertise was in tooling
design. He told me that Sport Aviation had erred slightly with the
description in the photo, they called the prop a single piece type, it
isn't; the blades clamp to a steel hub. While the initial setting is
adjustable, customers do not get to change the pitch themselves.
Estimates are made as to what the initial pitch should be and the prop
is sent with two pairs of indexed clamps for the hub that, when clamped
around the prop bases, will give the prop the correct pitch. If, in
testing, it turns out that the prop needs to be repitched, one each of
the two sets of clamps are sent back and they are re-indexed by Global
QCS and returned to you. You re-clamp the prop and it now assumes the
new pitch. Other than that, there is no owner adjustment possible.
The rep talked about how they manufacture the blades so that there are
absolutely positively no voids in the composite blanks. The blades are
made of a composite of materials all predicted by computer design to
flex from 6 to 8 during flight. In other words, no guesswork. It
took them 18 months to model the first prop, and 9 months to complete
the second one. Engineers were hired from all over the space, aviation
industry and prop industry to put their collective minds behind this
project. Global successfully competed with other companies for NASA
SPIR funding with which to hire the many engineers who are working on
the research. If I'm remembering the conversation correctly the
president of Global, Michael Smith, had been wanting to pull together
all the various techniques and concepts of a fixed pitch constant speed
and combine them with state of the art composites and resins to create
this prop.
One thing he stressed over and over was that the airfoils were exactly
the same, one after the other. They come out of the molds that way.
He mentioned that they got a certified fixed pitch prop in their shop
for analysis and comparison and were surprised to find that the blades
were not the same one side to the other. "One side had a flat spot on
the airfoil not duplicated by the other blade" he said. QCS has
achieved precision repeatability, each blade is an exact duplicate of
all the others. I was told the blades are so light they were
considering adding some mass to them so that engines won't run rough at
slow speeds without the flywheel effect of a heavy prop to carry them
around in between power pulses.
The blades are molded to steel shanks and are currently being run on
the test stand at 135% rpm.
Yet another feature of the blades is that they incorporate modern
airfoils not used in props previously. Many certified props simply
have a flat back to them, possibly because of the difficulty of
manufacturing intricate shapes in metal. I've read elsewhere that
often the ubiquitous Clark-Y airfoil is what many props use. At QCS
the computer modeling suggested a turned down rear edge near the hub, a
"cusp" it was called which causes the top and bottom airflow off the
trailing edge to be more parallel which reduces turbulence.
Finally, I asked him if he minded if I posted this information to the
news group. He said he didn't mind but asked that I wait until he
could send me their information sheet so that I didn't get any of what
he was telling me wrong. So I waited and it arrived yesterday. You
see it complete below:
***Begin quote***
Global QCS Composite Propeller
"Global Aircraft Corporation has designed, fabricated and is currently
testing a flexible, quasi-constant speed, composite propeller for use
on General Aviation and Experimental aircraft. Initial production is
scheduled for January 1998 and FAA certification is anticipated by mid
1998.
The Global QCS Propeller Team has developed a unique propeller design
methodology that defines the geometric shape of the propeller blade.
Developed through cooperative research and development contracts with
NASA, the Global Quasi-Constant Speed (QCS) Propeller is the first
major improvement in fixed-pitch propellers for General Aviation
aircraft since the 1930's. Utilizing the integration of aerodynamics,
non-linear structural analysis, state-of-the-art aero-elastic analysis
and advanced composite manufacturing capability, the propeller design
process uses sound analytical approaches and Computational Fluid
Dynamic (CFD) simulation coupled with full-scale test verification.
The QCS Propeller is fabricated with advanced composite materials and
resin transfer molding processes in precision closed-cavity molds. The
revolutionary innovations of the Global QCS Propeller are its ability
to flex (change pitch) predictably under operating loads, performing
similarly to variable pitch propellers, and reduced noise levels
achieved through modern propeller acoustic design. Increased
performance and efficiency over fixed pitch propellers include 35%
reduction in take-off distance, 40% increase in rate-of-climb, and 10%
increase in cruise speed. The QCS Propeller retains the advantages of
a fixed pitch propeller, specifically, low cost, low weight, low
maintenance, and simple operation with no requirement for engine
pitch/speed control. No other fixed-pitch propeller demonstrates
comparable characteristics.
The Global QCS Propeller is currently being developed for 160 to 210
horsepower engines. Production of propellers for experimental
airplanes is scheduled for early 1998. Production of FAA certified
propellers for certified airplanes is scheduled for mid 1998. QCS
Propellers for special applications can be developed under special
agreement." *** end of quote***
Will this be what it appears it can be? Will this prop revolutionize
the propeller industry? I don't know but we will soon find out as the
first version for experimental aircraft is due to fly shortly.
And the cost? They really haven't gotten into production yet but were
forced to toss out some ballpark figures. They felt that $3500 for the
160 hp engine and $4500 for the 210 hp engine was a good starting
point.
My personal feeling, and I'm going out on a limb here, is that this is
a truly significant advancement in aviation. If it actually manages
the performance figures the computer modeling predicts, they will be
HUGELY successful. Imagine constant speed prop performance with a
lightweight fixed pitch prop. And while $3500 is not cheap, it's a
bunch less than a constant speed.
Actually, it doesn't end there. QCS is also computer modeling cowlings
for aircraft. He said that little work has been done on cowlings and
noise abatement and cooling design recently. Some cowlings act as a
drum, picking up the beat of the prop and amplifying it. This is
something that a properly designed and constructed cowling could
minimize. So my worry about a needing a slow turning prop to keep it
quiet may be over. If this prop can be quiet at 2500 to 2700 rpms
because of its accoustical design then little, if any sacrifice need be
made to performance. And that's STILL not all. They are working on a
prop for a direct drive engine, something that will be turning 4700
rpms on the formula one circuit. Owners of direct drive engines might
want to pay attention to this research.
Sure hope the testing verifies the computer model.
Corky Scott
PS, I was also warned that at least one manufacturer of composite props
appeared unable to make them without voids in the blades. He was of
the opinion that this is a dangerous practice.

Yes sir. I'm hoping you have Windows 95 cause here goes! (I've suffered the
same problem)
-First, highlight the URL of the web site
-Next, right click and and from the menu that pops up, select, "Copy"
-Then, go to your desktop, and right click again. On the menu that pops up,
select "New" and then, from that menu, select "Shortcut".
-A type of Wizard will pop up. WHere it asks the location of the target, you
paste the URL there (Make sure it includes the prefix http://......)
-Once the URL is in, press "Next"
-Now type in the name you want to give the shortcut "make it obvious"
-press "finish"
-Viola, you have an internet shortcut.
-Now just double click on it and you go directly to the site! (Assuming you
are connected to the internet)
Hope that does it! E-mail if you need
more help

IAS is what the airframe experiences. That is, 210 IAS "feels" like
210 to the airframe, regardless of density altitude. So 210 IAS is
the Vne.

I wouldn't worry about "not getting the full building experience"
if you get the quickbuild. There is still more work than you can
possibly imagine (not to scare anybody off). I think the best
approach is building the tailkit to see how you like it (and
learning everything you need to know) and *then* plunk down
the big bucks for the QB. I did it this way, and I was real happy
I had done the tail before cutting into the fuselage skins, etc.

I just finished building my two-piece metal fairings and am in the
process of fitting the wheel pants. I am kind of reluctant to change at
this point, but I figure if I'm going to then I'd better do so before I
get into all the intersection fairing work. I am agonizing a bit over
whether to make this change. Can I hear a little more about these
fairings? Are they that much better? Do they attach the same way or
are they bonded on? Will they fit the same over my painstakingly
crafted wooden gear leg stiffeners?
I'm not that concerned about the cosmetic aspect, but if there's a
reasonable performance gain to be had, I may reconsider.

Jim,
There's a ton of information about the various electronic engine monitors
in the RV-archives, including a general comparison I did. Also, be aware
that the Vision comes with all necessary sensors, the RMI device does not
(which means the price is more like 1/2, not 1/3). Both very nice

Vne (and other V speeds) are always indicated airspeeds. The indicated
speed is a measure of the force the air is putting on the plane, and so
aircraft behavior will vary much less with indicated speed than true
speed. As an example, the indicated stall speed will vary little with
altitude, but the true stall speed changes alot.

Download IE 4.0 with Outlook Express mail. Then you can click on the
www.???? address right from the mail program. If you like what you see you
can save it right to your RV folder on your favorites (bookmark) lists. I
have not seen the latest version of Netscape, but I think IE is great!
Some other things that are neat. In Outlook Express you can use inbox
assistant to send all of your RV-list msgs to your RV-list folder. This way
you can read your RV mail when you have time and deal with the other stuff
imeadiately ( or you can ignore your work related mail and read the RV list
first). You can also ckick on the subject header and have your mail
imeadiately sorted by the subject (thread). I think Microsoft has really
hit the nail with IE 4.0 and Outlook Express.

Why not use mil-spec? It doesn't take much and it's easy to get.
Mil-W-22759/16 wire is the wire of choice and sold by the foot
by Aircraft Spruce et. als. If you've got an avionics shop or
FBO with a good repair shop nearby, they may sell you short pieces
of the fatter wires for landing lights and pitot heat.
The problem with most other wires is their insulation. If not a
close cousin to teflon (22759 is Tefzel), the insulation gets
brittle with age and WILL be a problem at some time in the future.

Sometimes redundant systems cause more problems then they solve. (e.g. higher

Maybe not on an RV, but some aircraft have a lot of trouble doing a go-around

64,66-69
From: | gasobek(at)juno.com (Gary A. Sobek) |
On a solo flight, I usually land with FULL flaps and the trim tab is
ALMOST FULL nose up just to remove the control pressure. I have MANUAL
aileron trim, MANUAL elevator trim and MANUAL flaps. The bad thing about
the manual flaps is: Do not attempt to put in the final notch until
below 65 Kts. They go down at 70 but it is not worth the extra effort.
I have also done a go around with full flaps on my first flight. I was
not climbing as fast as I should because of the full flaps. I forgot to
put them up. When I reached 200 AGL, I retracted all the flaps at once.
I was climbing faster with full flaps than a Cessna 152 does under
perfect conditions. The RV-6 flys very well with full flaps up to 100
mph (87 Kts). I have not tried flying with full nose down trim but one
friend with a -4 has and said it can be done. He has the electric
elevator trim and did this as a failure mode test.
If failure mode analysis is done as Bob suggests, there will be a
procedure to cope with any failure. I have a basic IFR -6 and have
nothing electric in it that I cannot live without. Need to get the DAR
back out and pay the $75 fee to have operating limitations ammended for
IFR. He knew I wanted IFR when the original operating limitations were
issued. He would not issue IFR until after test flying was complete.

Jerry has a reputation for making very high guality fiberglass parts. He
also has a reputation for being VERY SLOW to deliver.
I ordered a set of gear leg fairings (and sent him a check) on May 18, 1996
(That's right: 1996). I still don't have them. I have called Jerry
monthly for the past year with no results. Since July, I've been telling

I'll be surprised if I EVER see my fairings or my money.

Subject: | Re: Electric Trim Runaway |
Bob described two unhappy events: runaway trim, and runaway
autopilot. Here are my solutions, for what they're worth:
My RV-6 (panel finished, not flying yet) has electric trim, actuated
via a MAC G-9 stick grip. I've experimented with physically holding
down one trim button (simulating broken-closed switch). When I hit
the opposite direction trim switch the trim stops moving (I'm 99%
sure this is correct... I removed the tail in preparation for
shipping, and can't run out and test it again right now).
If one trim button fails (contacts closed) my normal reaction would
be to apply stick pressure and hit the other trim button. That
would stop the uncommanded trim tab movement. The trim tab wouldn't
move as long as I continued to hold the "opposite" trim button down.
The fact that my trim input had no impact on control pressure would
be my clue that the trim system was messed up, and I could then pull
the trim breaker to shut the system down. Then I would release the
"opposite" trim button.
I think I like Bob's button + coolie hat approach better. With Bob's
concept one just releases the "second" switch and the whole sytem
shuts down. Elegant.
Runaway autopilot: I'm using a Navaid devices autopilot. One of the
preflight actions is to ensure that the clutch is adjusted so that I
can overpower the servo. In addition, I've added a button on my
MAC-9 grip that controls a relay between the autopilot "brain" and
servo. With a press of the button I can kill the power to the servo,
then relax and turn off the autopilot switch (or pull the breaker).
A neat side effect of this arrangement is that I can temporarily
disable the servo in order to drop a wing if I'm scanning for
landmarks. As soon as I release the button the autopilot resumes its
duties without having to be reset.

They do now, but have you noticed? GA fleet is down by about 50,000
airplanes
in 10 years . . . 5,000 per year. Is the effort in Independence, KS going
to reverse or even slow that decline? I suspect not.

I'm not sure that's true but I cannot prove it. But consider this.
Of all the best engineers I have working with me at Raytheon, two
have degrees in engineering and they finished those AFTER they came
to work for us. I don't have a degree in anything. My best software
guy has a degree in chemical engineering. Our best electro-wienie has
a degree in photography!
I heard a thesis brought forward on the radio a few days ago that
zoos and botanicals are failing miserably in their goals to educate
and motivate people toward conservation . . . instead of teaching people
the joys of viewing nature in the wild, they seem instead to foster yet
more urges to put nature on display in cages and inner-city gardens.
It's these kinds of observations that make me wonder how many people
who walk through the gates at OSH are really motivated to become active
aviation participants in aviation at some later date? To be sure, from
the shear masses who attend every year, there are a lot but is the rate
of return on investment really there? We'll never really know any more
than we can demonstrate that the department of Health, Education and
Welfare ever improved the status of a single human being.
Something I do have confidence in is one-on-one contact with people
who show an interest. I think some people call it mentorship. It seems
like a waste of resources because you're concentrating on so very few
but you can certainly observe and record the results . . .

Hmmm . . .I'll have to think about that. I've got a teenager who spends
a LOT of time under his truck . . . he's motivated enough to spend the
time and effort when it comes to his basic needs . . and he does have
a fondness for cheap Chinese tennis shoes at $100/pair but when I offered
to pay for his flying lessons in the Beech flying club, he demured when
he browsed through the stack of books . . .
Do you thing there is a future for $150,000+ personally owned airplanes?

A friend of mine made an interesting observation a few weeks ago. He
says we owe the Wright brothers a real debt of gratitude. I agreed but
I wasn't sure why he'd brought it up. He went on to explain that when
they beat Langley to the punch, it was demonstrated for all time that
ordinary
private citizens could take on a task an succeed even when a government
backed military organization lacked the vision and investment to
bring an idea to fruition. Had Langley been first, the government would
have put a regulatory lid on it (in the intereset of national security)
before private citizens could duplicate the work. The Wright brothers
were initial suppliers of technology to the military and set an
important
precedent. Amateur aviation showed us how to do it at the beginning and
I think we may have to depend on it to show us how to save it. Regulation
and corporate lethargy are killing GA as we've known if for 50 years.

No, please don't! There's value in the exchange of views and ideas.
From inside the industry, I have a decidedly different viewpoint of
aviation's future. I must admit that right now, I don't put much
stock in the traditional sources of little airplanes filling the
gap between flight training and Kingairs. Independence KS is the
Jurasic Park of aviation . . . they're cloning dinosaurs in the
form of brand new, 40-year old airplanes . . . oh yes, they've
tinkered, prodded and put on new paint stripes but I was working
for them in 1965 when we were doing EXACTLY the same thing on
the almost EXACTLY the same airplanes . . . how much have cars
changed in 32 years?
If one wants value and modern technology in an airplane, he'll have
to build it. Aviation under the umbrella of TC/STC/PMA is dying
and I don't see needed changes coming from Washington -or- Wichita.

Rick, I can answer that question. The plane is testing two different types
of gear leg fairings. With the new flat bar gear, Van did not know how
much they would flex and whether it would be stiff enough for an aluminum
fairing. Obviously, it flexes enough that the single piece fairing will
not work. The other gear leg fairing is made of fiberglass. It is also a
single piece but must flex enough with the leg. I do not know what type of
fairing Van will provide with the kit, but I can tell you one type of
fairing he will NOT provide! Bill

Hi Chris,
I'm at exactly the same place you are. And I'm doing it the very easy
way.
I have the fuselage on a spit ( like bar-b-q style) I simply rotate it to
the exact position I need and just lean inside to do the work.
I use a one inch pipe flange (the flange you can bolt to the ceiling then
screw the pipe into) one at each end of the fuselage (well actually I use
two at the rear). At the front I weld an elbow in place to fashion the
handle.
I drilled a hole through the handle, then tru the plywood backboard in
several places to make it stay in any one position or it can free wheel
if needed.

Jim,
I have one in my RV-6A and love it. The kit was easy to assemble. It is
very light and doesn't take up much panel space. The display is laid out
logically and is easy to interpret during flight. I really enjoy being able
to set the prop +/- 10 RPM and map +/- 0.1" Hg. Ok, I'm anal :)
Ron Mower from RMI is a great guy to work with. He stands by his product
and will openly admit and fix any known problems. His honestly and
commitment to customer service is second to none. I did something real
stupid during assembly and fried a few chips. It was all my fault, no ifs
ands or butts about it. The unit was shipped to RMI for diagnosis and
repair. They fixed it and paid for return shipping and didn't even send me
a bill.
I have no regrets by using this unit. Knowing what I know now, I would do
it all over again and would recommend this unit without hesitation. Can you
guess that I like it?
Let me know if you need any additional info.
Hope this helps.

All Vspeeds are traditionally given in Calibrated Airspeed (CAS). That is,
Indicated Airspeed (IAS) corrected for instrument errors. If you have
negligible instrument error, you should use 210 mph indicated as Vne
regardless of altitude or temp.
Hope this helps.

<< Pulling a breaker on trim runaway is too time consuming and there's
a lot of window for error. If your trim breaker is located in a whole
nest of other breakers, the possiblity of pulling the wrong one in
time of "tense pilot response" is great. Pulling the wrong one may
no have electrical consequences for flight for inadvertently shutting
down another system but it adds still more delays in perception and
resolution of multiple problems . . . all design and/or pilot induced.
In any case, pulling the breaker is far more time consuming than some
alternatives. During trim runaway, time is of the essence. The longer
you delay in effecting shutdown, the further out-of-trim the airplane
is going to be when the motor stops running . . . we need to shave
tens of milliseconds off of the perception-reaction-action time needed
to bring things under control.

Bob,
Come on now. Its time to give a little. The breaker for your electric trim
need not be mounted amongst all the others. One could easily be mounted it in
a handy location and even color coded if necessary. You are correct time is
of the essence, it doesent matter weather your flipping a switch or pulling a
breaker. The key is to identify and react. In other words you must always be
mentally prepared. I try to stay on my toe's and remember this especially
when it comes to my trim system. On two occasions I had the edge of my
sectional accidentally hit the cooly hat and begin driving my trim downward.
My first thought both times was to go for the breaker, however as soon as I
pulled my hand from under the sectional it stopped. whew releif ! It does get
your attention real quick. Keep pounding away Bob! I value your opinion, you
put out some great stuff but I think I like this one the way I did it.

Andy,
Vne and all the other V-speeds are based on the dynamic pressure of
the airflow and resulting aerodynamic forces. From a practical
standpoint this is your indicated airspeed (the difference between
pitot and static pressures), but for purists it is calibrated
airspeed (i.e. indicated corrected for pitot-static system errors).
If you've ever heard the term max-Q during a rocket launch, it's the
point of greatest dynamic pressure and is where the pressure buildup
from increasing speed is offset by the decrease in pressure due to
lowering air density with altitude. We get the same, albeit less
dramatic, effect of increasing true airspeed for the same dynamic
pressure as the altitude increases. Just think, the shuttle in orbit
has an indicated airspeed of zero;-)

It's hard to answer your question without knowing what platform
and browser you're using (though you did mention Netscape). But
here are some possibilities.
(1) If you use your browser to read your email, the browser will
automatically convert the URL for the web page into a link. For
example, if someone writes "see my home page at
http://www.somewhere.com/" the 'http://www.somewhere.com/' part of
the message will become an active link to the web site. You can
just select it, jump to the site, and then select "Add to Bookmarks"
from the Bookmarks menu.
(2) Cut and past. Most platforms (Mac, Unix, or--ugh--Windows NT/95)
support cutting and pasting in one form or another. You can highlight
the text in the email, copy it, then paste it into the Location field
on your browser (the place you would normally type it).
(3) If you're on Unix (yeah), you can use a nifty program called
Hypermail to convert your email inbasket to a web page on your own
computer. You can then view the web page, sorted either by thread,
subject, date, or author. URLs (web addresses) that people put in
their messages automatically become links (as in #1, above).
I use Hypermail on unix, together with a mail filter called Procmail.
Together, they automatically send my RV List messages into a special
file, and turn the file into an organized web site that I read with
Netscape. This is _much_ better than sorting through the messages
with an email program.
I haven't used some of the more sophisticated email programs, such as
Eudora or CC:Mail. I think some of them combine email and browser
capabilities. You might want to investigate them.

Royce,
.... I made up an internal 0.032 plate with floating nutplates on
it. There have been some reports of the single layer rear bulkhead of the
-6A being a little weak, and having failures/distortion at the tiedown
bracket attachment. This internal plate also acts as a doubler as well as
removing the need for finding a midget with triple jointed arms to tighten
the nuts ...:^) The plate can be inserted through the large hole under the
HS and thne moved aft into it's final position.
Not an original idea ... I've seen others built this way ... and
I'm sure I'll be much happier at final assembly time.

Subject: | Re: Electric Trim Runaway |
Bob described two unhappy events: runaway trim, and runaway
autopilot. Here are my solutions, for what they're worth:
My RV-6 (panel finished, not flying yet) has electric trim, actuated
via a MAC G-9 stick grip. I've experimented with physically holding
down one trim button (simulating broken-closed switch). When I hit
the opposite direction trim switch the trim stops moving (I'm 99%
sure this is correct... I removed the tail in preparation for
shipping, and can't run out and test it again right now).
If one trim button fails (contacts closed) my normal reaction would
be to apply stick pressure and hit the other trim button. That
would stop the uncommanded trim tab movement. The trim tab wouldn't
move as long as I continued to hold the "opposite" trim button down.
The fact that my trim input had no impact on control pressure would
be my clue that the trim system was messed up, and I could then pull
the trim breaker to shut the system down. Then I would release the
"opposite" trim button.
I think I like Bob's button + coolie hat approach better. With Bob's
concept one just releases the "second" switch and the whole sytem
shuts down. Elegant.
Runaway autopilot: I'm using a Navaid devices autopilot. One of the
preflight actions is to ensure that the clutch is adjusted so that I
can overpower the servo. In addition, I've added a button on my
MAC-9 grip that controls a relay between the autopilot "brain" and
servo. With a press of the button I can kill the power to the servo,
then relax and turn off the autopilot switch (or pull the breaker).
A neat side effect of this arrangement is that I can temporarily
disable the servo in order to drop a wing if I'm scanning for
landmarks. As soon as I release the button the autopilot resumes its
duties without having to be reset.

I'm assuming that you are using NetScape for both email and browsing.
If the posted homepage is actually a link (highlighted), you can click
on it to go there, add the bookmark (Ctrl-D, or Bookmark menu/Add

isn't a link, or if you don't want to wait for the page to display; you
can select the homepage reference by highlighting it with the mouse and
copying the text to the clipboard with the Copy command on the Edit menu
(or just type Ctrl-C). Then you can paste the text into your bookmark
file with the Paste command on the Edit menu (or type Ctrl-V). Just open
your bookmarks with a Ctrl-B from the Browser window (Bookmark menu, Go
to bookmarks); insert a new bookmark (Item menu, Insert bookmark); and
paste the text into the location field. You have a name and a
description available to you as well. This process is easier to do than
it is too describe, so don't let my long rambling directions throw you
off!!
Good luck!

I am pleased that you have taken the time and trouble to explore
the corners of the envelope on your own terms. You have a distinct
advantage over many other pilots (1) you've acquired some knowlege
as to the boundries on problems you may be presented with in the
future (2) you have "flown" the airplane and convinced yourself
that pilot workload in any possible situation is reasonable and
(3) should the worst happen, it isn't a total surprise for which you
have no previously considered response. Plan B for that situation is
alive and well in your cockpit.
Would that all spam can pilots know their airplanes so well. Somebody
made a statement that their particular aircraft's out of trim limts
were no worse than a 172 and no big deal . . Hmmmm . . . There are
three models of 172 on the field where I fly most often . . . got
to fly Young Eagles out there next Sat . . . I think I'm going to
spend a few minutes in each of those airplanes and see if my own
calibration agrees with the statement.

I tried sending this once before, but got no mail for 3 days and never saw

elevator trim. If you have a stuck switch or relay, in other words a runaway
trim. I for one would like to be able to reach over and pull the breaker
before the situation becomes critical. Now I suppose I could wire in a
cuttout switch if I wanted to, but that would fall under complicating the
system. I know for a fact if the trim were all the way to one extreme you
would have a hell of a time bringing the airplane back in one piece. I would
consider this a saftey of flight item.

Subject: | Re: countersinking after dimpling |
Morning all,
In the builders supplement Vans mentions that it is sometimes beneficial to
lightly touch dimpled holes with a countersink cutter to clean them up. I
have found that when dimpling sheets .032 and thicker it makes a big
difference in the finished surface. All it does is square up the sides of
the dimple to match the rivet heads. Do just enough to remove the finish
on the sheet but be carefull and practice first. As your dimple dies get
older, or if you are not using the $38.00 dimple dies to begin with, this
technique really makes a difference.
Hope it helps.

I'd suggest that the converse argument be made. Mechnical stops
on pitch trim should be set to allow only necessary trim settings
to accomodate the airplane over it's speed/c.g. envelope.

Exactly. One of the airplanes I'm working with was built with
6" wide tabs that run the full length of the elevators on BOTH
sides. The builders installed dual trim actuators. A common complaint
now is "Gee . . . I just barely touch the trim control and it moves
too far." Further investigation shows that the full range of
NEEDED trim is only about 10% of AVAILABLE trim. Electric actuators
on this airplane is an accident waiting for a place to happen.
Even if one sets good mechanical limits to cover the speed/c.g. envelope
it's still important to know how the airplane behaves should trim
be forced to either limit. I know that doing touch and go landings
in an A-36 can make the critter a handful if you don't give the trim
wheel about three good throws of nose down before you put power back
in for takeoff. Mechanical stops are a good thing but it's not the
whole answer . . . the whole discussiont about trim runaway is unresolvable
until the trim system is analyzed for EACH airframe.
Another ON-POINT comment:

No truer words spoken . . . see why I'm so rabid about cockpit simplicity
and architectures for Plan A/Plan B training? Look through any 100 NTSB
accident reports and compare numbers of accidents with human factors
contributions versus mechanical failures. Like people who write
regulations,
it's an easy knock-off to say we've deduced procedures or put tools in
place for every contingency . . . but you cannot regulate pilot attitudes,
perceptions and operating skills with an element of surprise. You can train
but who has the time or dollars and how many would submit to mandatory
training? Only I can take on responsability for how well I can perform.
In my limited experience in airplanes, my pucker-factor has peaked at over
100 psi on several occasions and none had anything to do with mechanics.

Paul,
Wow, the price is not a factor for you? Must be nice. My thoughts on
the quick-build: The work already done for you is certainly worth the
price if you can afford it. It took me three or four years to get
roughly to the point where the QB begins. The workmanship on the QB is
very good, unless you want to build a showplane.
On the downside: If this is your first project, you will find yourself
jumping right into the more difficult parts of the project without the
benefit of experience on the earlier parts. I screwed up several parts
in the tail kit and just ordered new ones at very little cost in money
and time. By now I am experienced enough that I make far fewer mistakes.
You will not have that luxury.
Finally, the newer kits for the RV-6 and RV-8 are so advanced that the
quickbuild versions offer relatively less advantage over the standard
kits. My next project will likely be a straight RV-8 kit, but I have not
ruled out a QB.

screen than the gps-89 , 90 and skystar types. Just my 2 cents worth.

I talked to Mr Felix about my prop situation this morning. He seems to
want to be very helpful. He looked up the s/n from the prop and said it
was originally cut for a glasair with a 150 hp engine. He said I should
be getting 185 mph at 2850 rpm's. I told him I wanted to see about 175
at 2500 but was only getting 140, and I wanted to max out at 2700. He
said he didn't understand the problem unless the prop has been whittled
on by someone else. I didn't think it had been because the stickers are
still on the prop. He said to send it back and he would measure it to
see if it was original, and if it was he could cut it to give me the
numbers I want. I mentioned I was using a warnke right now and he said
Mr Warnke had cancer and he wasn't sure if he would be doing any more
prop work. Over all he seemed rather anxious to please. He also said
if the prop couldn't be cut he would give me 200 bucks for it outright
or towards another prop. His new props are 610 dollars. Sounds good to
me. . I did my first spins the other day. It spun at about 1 turn per
second, best I could tell. Maybe I did it wrong, but it seemed more
like a graveyard spiral, to me. Recovery was almost instant. My head

cable
did you use and where did you get it? Also, how did you made the
connecton from the short cable to the servo? Where did you place
your
servo inside the fuselage? Or did you place it in the area under
the
horizontal stabalizer/vertical stabalizer fairing?

Subject: | Heated pitot tubes |
A post earlier today, before there was a problem with the system,
from
Dave Jones asked for information about a heated pitot tube
installation.
I can help with this request.
I make and sell a heated pitot tube mounting bracket kit for
installation on RV's and comes with all hardware and installation
instructions with photos. I also sell a heated pitot tube at
competitive prices. The pitot tub is the popular AN5814 (12 volt).
It
is the one that has the static port in it so there is no need to
install static lines running to the back of the fuselage. The
brackets
are available in a chrome finish to match the pitot tube, and are
also
availabe in a paintable version.
If you Dave, or anone else is interested in my products please
contact
me and I will send you a flyer on the products.

Guys,
.... there is another way that I think is a little cleaner and
certainly cheaper. The trouble with a throttle cable is it's length (and
it's $50 price), which ends up putting the servo in some way inaccessible
place in the aft fuselage with no good mounting surface handy. A much
shorter cable would put the servo on the flat F-614 deck under the tail
surfaces, where it would be accessible by removing the F-694B fiberglass
fairing. I was ready to special order a shorter cable, and then a catalog
arrived!
Airparts Inc., Kansas City 800-800-3229 (the ads with the lady in
the roll of aluminum ..:^) have surplus 24 inch push-pull cables on sale
for $4.20 each. These have 10-32 threaded, swivels at both ends and a
threaded mount at one end that will thread into Vans WD-415 weldment.
Sounded close to what I wanted. I bought one (well actually two, since
they have a $10 minimum order ..:^) They do not have a vinyl jacket like
Vans cables, but a couple of layers of 3/8 diameter heat shrink tubing gave
me a nice looking plastic jacket.
I mounted mine as shown in the plans on the elevator, and routed
the new trim cable basically as shown on the plans, but through the center
lightening hole in the HS-405 rib ibnstead of the forward one. This will
make the location of the servo closer to the centerline for easier access.
The 5/8 hole in the main horizontal stab. spar will now be 3.5 inches out
from the centerline. The moving portion will penetrate this hole, so I
will fabricate an angle bracket riveted to HS-405 and use a 1/4 inch Adel
clamp to solidly anchor the forward end of the trim cable. A mounting
plate needs to be fabricated to hold the servo about 1 inch (whatever
measurement it takes to keep the trim cable in a flat, horizontal plane)
above the F-614 deck.
I think this will be a cleaner system, with better
accessibility, than using a throttle cable that Bill B. describes. Don't
forget that the WD-415 trim cable anchor weldment (the nut on a I inch sq.
SS plate) is part of the finish kit, and you might need to order one
seperately from Vans ($6.09 last week).
FOR SLOW BUILDERS ONLY:
Those of you with old elevators - I'm a slow builder ..:^( will
have a royal pain in the ^&&%$ if you built before Rev 3 of sheet 5 (now
sheet 5a), and have to open up the 7/16 hole in the WD-405 elevator horn.
I managed to use a 1/2 inch Unibit on an extension, got a 1/2 hole and then
used a slightly modified SB-625-6 (not a -7 as now called out) plastic
bushing. No way could I work out how to get that hole to be enlarged to
5/8 working through the slot in the pop-riveted leading edge of the elevator.
Interestingly enough, I got one of these -6 bushings to fit into
the main spar of the horizontal stab. by filing off the "lip" on two sides.
I could get a 1/2 hole in my main stab. spar without hitting the spar
caps. Seems tidier than no bushing and using the RTV approach.
... hope this helps some others considering a hybrid trim
cable/servo approach.

Unless you're dealing with limiting mach numbers, VNE is indicated airspeed.

Hello out there!
Is it just me, or are the rest of you getting a lot of this:
<<< No Message Collected >>>
I'm also getting three and four of some messages that are several days old.
I have a sneaking suspicion that I'm missing out on a lot of good information.
I will post this only once, so if it shows up several times it's not me!

No contest here. I built my -6 in my garage and am now building an -8 in an
airport hangar. Go with the garage, you will accomplish much more at home.
You'll be suprised how often you go out and only work for an hour or so. You
likely won't do that in your hangar.

Charles,
I would advise you build at home, unless you live close to the airport and
dont mind spending all of you free time there. It wont take a couple of weeks
before your wife is complaining that your never home. Compromise and build on
your cars side of the garage. I think you will find that the building process
will go a lot quicker this way. I was able to keep one car in the garage
throughout most of the project.

Warren,
I have done a few retrofits for freinds in the area. Its not that difficult
to install the trim motor in the elevator even after the elevator has been
completed. Some people buy a short cable and install the trim unit back in
the rear of the fuselage somewhere. You could also use the long cable and
install the trim unit up front either mounting it on the sidewall or under
the floor someplace. Give me a call if you want, im home for the weekend.
Ive seen most of these posts about 3 times now. Whats up with that Matt? Not
that I mind we are stuck in winter hell this weekend, nothing else to
do.Denver wont say the airport is closed ( you all know this is the worlds
only all weather airport right?) The main road in is closed and all airlines
have cancelled all flights for today . Its not closed but no one can use it ,
get in or out of it ;<). Hope all in this area are home and warm!

Subject: | fiberglass scraps anyone??? |
Does anybody have a few scraps of Vans' fiberglass pieces? Stuff lying
in your trash that you cut off from the raw cowl or rudder fairing or
whatever?
I need 3 or 4 small pieces perhaps 2"x3" which I want to use to do a
test of how ethanol enhanced auto fuel effects various types of
fiberglass composites.
Its not for an RV related project. However, other planes we fly use
fiberglass fuel tanks and auto gas. Some people have reported a
softening and delamination of their tanks and we suspect ethanol content
has something to do with it.
If anybody can stick a couple of scrap pieces in the mail to me I would
really appreciate it. I already have samples made up of auto parts store
type epoxy layups, however, I'd like to test with various types of
glass.
Thanks,

Bruce,
Normally I would agree with you. I to like manual controls. After seeing how
difficult it was to opperate the flap lever with a passenger in the 4 I
elected to go electric for room sake. The reason I chose the electric elevator
trim was the same, less clutter.

Micheal,
I dont mean to be discouraging. Im sure Mr. Felix will try his best to give
you the performance you are asking for. I think you will find after a few
atempts you may not get what you hoped for. Ill bet the first thing he tells
you is either that prop has been worked on by someone else, or he cant bring
that prop to your requirement. Make sure if you send him that extra money that
he guarantees you will get what you asked for or your money back.

John,
I guess my meaning wasnt clear. I didnt mean that at full travel I could not
control the airpane. What I meant was it would be a handfull. Sure I could
maintain altitude for any length of time, but imagine how much fun the landing
flair would be. Once on the ground If one were to relax to soon. Well im sure
you get my drift.

Hello
I'm a french hombuilder, new on the list and my english is poor (sorry):-(
I have bought a Lycoming O360A1AD for the RV4 I'm building (I LOVE this taildragger
!)
and the propeller wich was with it. They come from a Socata TB 10 (french made
plane).
My problem is that this propeller ( c/s Hartzell HC-C2YK-1BF )is 74.5 inch dia.
