Got a electronically chaleged question. The pitot blade (Piper Type) has
two wires, there is "P" stamp next to one and a "S" stamped to the other. My
guess was P stood for wire to pressure and S stood for the wire static for
heating. Does that make sense to the electrons?

Our Friday message created some confusion regarding horsepower. In that message
we noted we had used nitrous for the climb competition at Sun'N Fun and also
that we were generating 200 h.p. Here is clarification: our engines are rated
at 200 h.p. without nitrous. With nitrous and increased r.p.m. we generate 350
h.p. This is what made the RV-3 especially potent in the climb competition
before we toasted the aft propeller shaft bearing at the completion of the
cross-country race where Alan Tolle placed first in class in his RV-3 and fifth
overall. On this prototype unit we will retain a plain bearing with some
related modifications. Even before Sun'N Fun we had already incorporated
numerous design refinements into the reduction gear assembly for subsequent
units. Amoung these was replacing this plain bearing with a ball bearing. The
base engine continues to do very well and we are exceptionally pleased with the
service of the various modifications, fuel injection, dual electronic ignition,
etc. A word of caution here folks regarding the use of nitrous on our engines.
We do not have alot of experience yet with this so it remains very experimental
and anybody considering it should proceed with measured caution. Additionally,
putting 350 h.p. through a two-balde wood propeller made it go through some very
strange contortions during testing prior to the time-to-climb race. Hope this
proves helpful.

I've come across a relatively inexpensive angle-of-attack device (RiteAngle,
about $200).
It requires the mounting of a small vane (2"x2.5") in a location where there
is a reliable, repeatable difference in the airflow over the vane itself and
the wing's actual AOA (best situation would be pure relative wind, but the
unit has adjustments to compensate).
Wingtip and L.E. boom locations have already been suggested, but I don't
like those due to aesthetics and damage vulnerability, etc.
I am thinking about a location under the wing somewhere around the pitot
tube. Anybody know how far below the wing you would have to go to get some
relative wind?
Thanks,

Subject: | One year down the track... Reflections. |
Hi Guys,
Well, it's a year since I received my empennage kit, so I thought I'd take
a moment to reflect:
1. During that year, I spent 350 hours building. A *lot* less than my
planned 1000 hours. In more recent months, my building hours are up to
round 50-60, which seems about the limit of what's sustainable long-term
for me. Based on this, it looks like my plane's about a 5-year project.
2. I now have a pile of quite aeroplane-like items; all the empennage
except the right elevator, and some wing spars. Looking at these, I
optimistically feel like I have a fifth of a plane; realistically I guess
that an eighth is probably about right.
3. I've spent in the region of US$5400 plus NZ$1500. Most of the US$ was on
the emp and wing kits (US$1095+US$3700), and a fair proportion of the rest
went on tools which I get to keep, but there's a heap of freight & tax
which is just lost money.
4. I started off fairly uncertain whether I was sufficiently motivated to
do a long-term project like this. I really wanted a plane, rather than to
build one. That's changed a bit; now I enjoy workshop time for it's own
sake rather than having to focus on the final product.
5. I've developed a lot of skills; I didn't realise how much until I helped
teach someone a few basic rivetting skills. Actually, the teaching was
quite difficult because lots of those skills have been unconscious habits,
like clamping things tightly together for drilling, and deburring parts.
6. I've gained a lot of confidence in using tools, putting things together,
figuring out things from plans, etc.
7. I've met many wonderful people, both in person and on the Net; I think
that homebuilders are perhaps the best bunch in the world! I couldn't have
done it without you guys... thanks.
8. I'm starting to think about what to build after the RV-6!
Frank.... 1 year down, only 4 to go!

I was not thrilled by the elevator control rod bolt being the "torque rod",
if you will, carrying all the connective responsibility of the two horns:
not only does it push and pull the elevators it also takes the shear stress
of any difference in pressure/load between the two elevators.
SOOOoooo.....after installation of the elevators on the fuselage, I made up
a small block to fit between the two horns and ran two AN-3 bolts through.
Now, the bolt from the control rod only carries the push/pull loads while
the two horns are bolted together, functioning as a single unit.
Just something else to think about..........

At Sun 'n Fun this year I saw an RV-4 with a small instrumnet panel

I've seen uph from both D J, and George and Becky Orndorff (GBI). The
product I've seen from both is high quality, but way different in approach to
the uph problem. GBI has an amazingly large quantity of fabric samples, so
much that it's hard to pick one! I use GBI for both my personal a/c and my
customer's because they're closer, and I prefer their solution for the uph
dilemma.
George & Becky came down to the Georgetown Fly-in this past weekend, and let

Hi all,
At Sun N Fun I fell in love with the fuel caps that ACS is selling. I forgot
who the manufacturer is but to say the least they are works of art. They
lock, and the mechanism is as smooth as silk as it opens. As I have not yet
built my tanks I would like to replace Van's standard caps with these. The
only place I want to pour fuel is in the tank, not on o-rings.
Has anyone installed these in a prepunched kit? These caps come in 10 hole
configuration but who knows if they will line up. If not, is it possible to
weld the holes shut then drill new ones. Or, in the opinions of those that
have gone before me, would it be acceptable to just fill the holes with pro
seal and then rotate the flange and drill new holes.
This is probably pretty mundane stuff so feel free to E-mail me privately.

Ron,
The vane is attached to a potentiometer, that output is used to drive a
display comprised of a vertical row of LED's. The two top LED's are red,
for stall and pre-stall AOA's. The rest are green in even AOA steps -
giving the ability to fly optimal AOA.
The unit also has audio warning options and a second "set" of critical AOA's
for flaps down condition. See
http://members.aol.com/elbie/riteangle/emhome.htm for details (the vane
shown is for a very slow ultralight, for an RV its much smaller at 2"x2.5"
on a 1" long arm).

As you have stated in your latest post, there are four wires on your
pitot tube. In that case, two wires are for the pitot, ram air
heating, and two are for the static air port. Also, as you mentioned,
one must check to see if any of the wires are grounded internally, if
they are, the grounded wires must be on the negative lead.
One might also check to see if there is resistance with an ohm meter
across the heater elements. This is to varify that there is indeed
good heater elements in the unit.

Some sort of epoxy primer would probably be your best choice for
compatability with unknown future finish paints. BUT.... I would
recommend against priming the exterior of your tail now. I did so
thinking that it would be good to protect it, but have since found out
that:
- Finish paint systems depend partially on "chemical bond", which goes
away if the primer has cured beyond a certain length of time
- If you have a paint shop paint your plane, they may not be willing to
guarantee their work if it's going over some "unknown" primer that
someone else put on, and may just want to strip it off anyway
- You'll be a lot more likely to be able to get any contaminants cleaned
off of bare aluminum than from primered surfaces

I just talked to Rick Bauerman, who is an applications engineer at
Hartzell. He confirmed that the M2YR-1BF/7666A-2 prop is only rated for
up to 3.8 Gs. Since that is the prop Steve Barnard builds his really neat
IO360 cowl around, and I am not interested in fiberglass work enough to
build my own cowl for the IO360, I'm afraid I'll have to stick to the
parallel valve 360 and the C2YK prop Van's supplies. While I don't intend
to do extensive aerobatics, it doesn't seem sensible to me to build a 6 G
sportplane and then put a 3.8 G prop on it. I'm sure others who want
their RV to be a cross-country rocket will enjoy the better aerodymanics
of Steve's cowl and longer prop. Rats! Oh well, at least I found out
before I spent the big bucks for an IO360.

Glenn, try a rivnut. They are basically a threaded tube that compresses
into a hole and grips on the blind side. There are a couple of
different methods of installing. The simplest is ...you guessed it...a
rivnut putter inner tool. Its like a popo rivet gun. Quite expensive
but you may be able to borrow one. The second is by using a special
mandrell and an allen key...this may be available from A/c Spruce.
You may also consider not using an Adell clamp if the bundle is not too
big. There are some small plastic clips that can be pop rivetted and
then a plastic tie wrap threaded through to hold the wires. An
electrical shop should have these. They are light and very inexpensive.

Hi,
To date, all my aerobatic flying has been in aircraft equipped with
inverted systems. I am in the process of building an RV-6. I am
debating putting in the fuel injection and inverted systems. I probably
will not put them in because I am well aware that the RV-6 is NOT a
highly aerobatic aircraft.
My question is......
On an RV-6 without inverted systems, what kinds of maneuvers can be
flown safely?
Thanks in advance,

Our Lycoming IO-360 runs well except during a go-around when power is
applied at zero or near zero manifold pressure. It coughs once or twice
before kicking in. Our initial thought is that the fuel injection system
is not adjusted properly. What are your thoughts. If you agree, could you
provide some advice about the correct adjustment to the fuel injection
system.

Try Rivnuts. Available from ACS, they are installed blind. Also if you're
securing wire, there are tywrap hold downs that have a 5/32 hole, and work
great with 5.32 pop rivets. Is you are securing wires near flight controls
use Adel clamps though. Tywraps may break over time and then the wires may
get into the controls.

haven't even bent up yet! The way I understand it and remember is that Van
doesn't recommend it for competition acro in a box.
As for the last question, I wouldn't recommend you doing 'prolonged'
inverted flight unless you do have the flops etc. So, anything with zero or
negative g for a period of time that will cause either fuel or oil
starvation is not desirable unless you don't mind engine stoppage due to no
fuel or no lube. This then leaves you to do almost anything that keeps
positive g on the frame.

Fellow listers,
I need the collective knowledge of the list to help me solve an annoying
problem with my RV-6. Since the first flight 10 days ago I am getting a
very loud noise in the cabin that starts at 120 knots IAS. Since the
first flight I have installed the wheel pants and gear leg fairings. I
have taped over the intersection where the future cuffs will go. I have
taped over scat hose inlets one at a time. All other fairings are tight.
This noise is strictly airspeed related. It sounds like a bad bearing in
an electric motor or a reed vibrating. It is so loud that it breaks the
squelch on the intercom. The noise is deafening with headsets off. I
have gone to 170 kts and the noise stays with me. If I make sudden pitch
changes the noise will change note or go away momentarily until relative
wind resumes normal angle.
I do have 2 bent whip comm antennas on the belly. I am going to try to
stick a small bead or ball on the end to change the harmonics. They may
be vibrating.
Other than that I am stumped. I will entertain any other ideas.

Any piece of wire of approximately 21" in length with do the job. If you

antenna off a car. you might have to modify the connector and mount and
cut it to 21" but it will work fine. Put the same device in an aircraft

Subject: | aileron/flap fitting |
Hi all,
After a trial fit of my flap and aileron to my wing still in the jig, I
have noticed a problem. Sighting along the trailing edge of the wing there
is a noticeable bow spanwise. Drawing a taught string along the top of the
two surfaces at the start of the trailing edge bend confirms that there is a
gap between the string and the flap/aileron top skin of about 1/16 inch.
My initial thought was that I had somehow built either the flap or aileron
with a slight twist. I rechecked these and confirmed that they were both
straight. I then drew my string across the top surface of the wing about 1
inch behind the rear spar rivet line and of course found this was also
bowed. How I got to this point without seeing the bow during construction, I
dont know. The bow is not obvious when sighting along the top of the wing
when the control surfaces are not attached.
Is this bow going to cause a problem for me or is it something that I will
be able to trim out in flight, so that it is only an aesthetic problem? At
this point my top skins are rivetted on but bottom skins are still clecoed
in place. Can I or should I attempt to fix this by pulling the rear spar
straight when I rivet on my bottom skins?
I visually checked the 3 RV's at the local airport and 2 of them appeared
to have bows one way or the other when sighting down the wing trailing
edges. I was unable to talk to the owners to see if they noticed any
controllability problems due to this. It is also possible that these
airplanes had twisted or misaligned surfaces rather than a bow in the wing.

Terry,
Do you have the tip up canopy? I had the same noise and the
problem was
air flowing under the forward canopy skin. I had used some spacers
between the canopy frame and the forward canopy skin. I sealed this area
with some non-corrosive RTV and the problem disappeared. You may not
have the same problem, but it will give you another area to examine.

I've been going to Quality Paints, an auto paint store in Hillsboro

So I was a bit surprised the other day to see a lot of the same stuff at

I searched the archive last night for ways people have sealed the access

I used fuel-lube on the stock cork gasket a few days ago during leak
testing and was thinking of changing to the pro-seal route for peace of
mind. I've ridden in a RV-6 with leaking fuel tanks and it make the
flight less than pleasant in the cockpit. So I'm hoping to get these
tanks sealed for good and never have to open them again. Okay, so
what's my point?
When I removed the sender and access plate from the fuel tank after leak
testing (the next day) I was suprised how "sticky" the fuel lube was and
I felt better about just using the cork gasket and fuel-lube.
Are there many people out there who have been flying RV's with this

pro-seal in each screw hole anyway to make sure those don't leak.

wrists due to keyboard use for 13+ years. In fact, clecoeing (is it Ok
to use clecoe as a verb?) is often a restful time for me. I get most
fatigued when drilling the vertical skins, especially on the higher
reaches, due to holding up the drill motor. Ok, so I'm not a weight
lifter. Are you possibly having to twist the clecoes out of the holes
because you are not compressing them completely? That's the only elbow
stress I could come up with as I self-consciously removed and replaced
clecoes (and now Judi is laughing hysterically at me, thank you very
much). I'd be interested if others have experienced problems.

BTW, I'm waiting for my painters to return from their vacation, so I

admiring the fit and looking for things to improve. Anyone else find

My QB wing rear spar was bowed by 3/32" in both planes from the factory
(wing number one, I hope number two is better).
I made sure the root/tip ends of the flap and aileron, and were they meet in
the center, were even with the top and bottom skins following the contour of
the wing. A string along the T.E. of the finished flap/aileron installation
reveals the same error as rear spar.
The naked eye can't tell, the entire top skin fit to the flap/aileron looks
good...so I hope it does not affect the way she flies.

Mike,
I have a pre-punched wing kit (RV4). They give you a neat template dwg of =
all the ribs. You use this for marking the flute locations. You just lay =
the rib on the dwg and line it up with the outline and then mark the flute =
locations. Neat, except you will find that the ribs vary quite a bit in bo=
th height and length. Since the
ribs are different lengths, I think that means that the rear spar will be w=
avy unless you do something about it. My ribs vary by as much as 1/4". I=

Someone was asking about using tooling holes. It is not unusual at all for=

Fellow Listers:
A quick electrical question. As I work on my RV-4, I am also restoring a
Citabria. I am adding Mitchell electric oil temp and pressure gauge.
Mitchell states these each pull .8 amps. I would prefer to protect both
these gauges with one CB or in-line fuse. Is there not a rule of thumb to
determine CB size for a particular load? I am assuming a 2 amp breaker
would be adequate for this application (total of 1.6 amp load).
As always thanks,

I've had tendonitis-like pains in my forearm from clecoing, and in the back
of my hand, but not elbow problems. But then, I haven't been working on
wing skins yet.
Incidentally, I have had the same problem when kayaking; the cocking
forward/backward movement of the right wrist at each paddle-stroke caused
tendonitis in the right forearm. Treatment was basically rest, and keeping
the arm supported and elevated (wrist at about chest level). As I recall,
recovery took a week or so. The movement is I think similar to clecoing.
Also, I've modified my cleco pliers a little; I ground a little out of the
jaws, so that clecos go in and out easier... I can easily shake a cleco
out, which allows for one-handed un-clecoing. Also, I added a light spring
stretched from the top jaw to the opposite handle, so that the pliers open
by themselves. I believe that this makes clecoing much easier.
Frank.

I believe that this ability to see when something is out of alignment by an eight
of an inch in twelve feet (1%!) is a skill one
gains from building things.
After building just one house, I can see when a window is not square or a corner
is not plumb. At first, I thought I was just imaging it but measuring things
that I would see, sometimes the error would be as little as 1%!
My wife and I made ourselves a pledge to never show people where we made little
errors. We just enjoyed the compliments in silence.
Maybe when your wings sit out in the sun, they will straighten out.

I think the circuit break's size is based on the wire size attached to it.
In your house, your kitchen is probably on a 20 amp circuit but your can opener
maybe only draws 1 amp. It could burn to a crisp, burn down the house! All
without ever tripping the breaker.
I've done a lot of house and car wiring but just learned this while building an

John,
I may not have been clear in describing the bow in my wing. The difference
in length rib - to - rib would result in a chordwise bow, but I wouldnt be
overly concerned about this. If you picture the airplane flying straight and
level, then the bow in my wing would be in a direction perpendicular to the
ground. The effect of this would be a continual change in incidence across
the span of the wing. In thinking about this in this way, I believe the
error is probably insignificant as it is a change of 1/16" over the chord of
the wing, or less than .2 degrees of incidence.
It is however, somewhat discouraging to sight down the trailing edge and be
able to see this deviation.

Do you need such a large hole? At one point, I experimented with putting
sellotape on filters to make nice fuzzy halo effects (for romantic wedding
photos). I was amazed at how small a circle I needed; less than an inch in
diameter.
If you have a large-format camera you want to mount, I guess you'd need a
larger hole. Or is the idea that you look round the camera to get a general
view of the ground? If so, it's going to be a tad difficult to look through
that hole whilst flying, and probably even more difficult for the passenger
to see through it.

Ed-
Jim Weir of RST told me once that just about anything will work better than
you need it to for AM/FM reception in the air. You can run RG-58 to the
outboard rib terminating with a crimp type BNC female bulkhead connector.
Use any old 30"-31" length of wire draped into the fiberglass wing tip
connected to the center of a BNC male connector. Then, a little soft music
and... mate them.
As an alternative without the sex (or the soft music), just run RG-58 out to
the wing tip and strip the last 30" or so of the jacket and shield off
(leaving just the insulated center conductor). You might cover the cut end
to eliminate the possibility that it might short out against any exposed
grounded metal.

I have some figures about my own installation. I have an Cessna 172
heated tube that I mounted just forward of the inspection panel on the

that the plans call for with the bent tube.
If I would do it again I would move it further away from the tie down

close to the jack.
I have the airspeed indicator from Vans and don't have any leaks in the
pitot/static system.
I used the method mentioned here in the past to determine TAS with 3

pressure altitude @ 28F. Using a E6B I found CAS. All speeds in knots.
80 IAS -- 80 CAS -- 90.5 TAS ** 2200rpm@13"

Please excuse my ignorance on such stuff, but it was a none coated(no flux
on it), sort of brown looking metal, not quite as large diam. as the coat
hanger, not brass. It was some a guy had given to me to bend ends in it to
make hangers for painted stuff. I don't know why the coat hanger did not
take solder, maybe I didn't get it hot enough. If the Radio Shack ant is
stainless steel, that keeps it from taking normal solder, doesn't it? I
guess just about any diam. wire that is stiff enough to 'keep it up' in the
wing tip would do it, as long as it will keep contact with the bulkhead
mount. Mine is curved outboard of the fitting, so that the wire is
compressed about one inch at the tip when the fiberglass tip is installed.
In my shade tree planing, this would wedge the wire into the inside of the
corner where the top of the tip folds into the bottom of the tip, there by
keeping the wire from vibrating and bouncing up and down, straining the
solder joint at the bulkhead fitting. Hows that for MIT engineering?

There's a popular mis-conception floating around suggesting
that breakers protect gizmos while in fact, a breaker or
fuse has the task of protecting only the wire which
branches off the distribution bus. The smallest practical
wire for airframe installations is 22AWG. Per the wire
table I published earlier this week, a 22AWG is good for
5amps in free air . . . (OOPS, just checked the table and
found I'd left out a couple of values. Here's the table
with the two missing numbers)
AWG Ohms/ 35C Rise 10C Rise Max Path
No. KFeet Amps Amps for .7 volt Loss
at 35C rating.
2 .156 100 54 45 Ft
4 .249 72 40 39 Ft
6 .395 54 30 32 Ft
8 .628 40 20 27 Ft
10 .999 30 15 23 Ft
12 1.59 20 12.5 22 Ft
14 2.53 15 10 18 Ft
16 4.01 12.5 7 14 Ft
18 6.39 10 5 11 Ft
20 10.2 7 4 10 Ft
22 16.1 5 3 8 Ft
So our 22AWG wire is good for 3 amps burried in
a wire bundle. In the suituation where we
intend to drive 1.6 amps of hardware, 22AWG
is adequate in any installation scenario. Further,
since the CONTINUOUS load is not over 3 amps,
we could burry the wire in a bundle and still
PROTECT it with a 5 amp breaker since any expected
overload would most likely be a hard fault. There's
no need to de-rate the wire for protection purposes
because the continuous duty load is so small.
In answer to the writer's question, any breaker
from 2 to 5 amps is okay in this situation. I'm
a little suspicious of the .8 amp figures for
power to operate those instruments; here's why.
.8 amps times 14 volts is over 11 watts. Since there's
no ENERGY coming out of this system other that to wiggle
some pointers on an insturment, ALL of this power comes
off as heat. Which gizmos in each system disipate all
or any part of this much energy? Certainly not the
instruments . . . anything more than about 2-3 watts
inside a plastic case would COOK the innards. How
about the transducers? Hmmmm . . . I suppose they
COULD stand that kind of dissipation, they're designed
to function in a warm environment. But when the
rest of the world routinely produces sensors that
operate with tens of milliamps, I'm having trouble
visualizing how the thing would be build to consume
10 times that amount of power.
I'd recommend rechecking the literature -or- contacting
the manufacturer -or- hooking them up on the bench
with a power supply and see what the real numbers
are. I SUSPECT they are considerably less.
This doesn't change the breaker sizing task but it
does afford more confidence in the system's ability
to survive . . . 11 watts is alot of snort to handle
in a task that's been seeing smaller and smaller
power requirements through the evolution of new
designs.

Bob . . .

In Bob Nuckolls' book he talks about using the actual voltage rating of the

not acceptable? This procedure would allow a much larger voltage drop than .7
volts. For example a system might be putting out 14.6 volts while a lamp was
rated for 13 volts. This would seem to allow a 1.6 volt drop.

Subject: | Vapor Lock ... In search of assistance |
I am posting this for a friend who recently purchased an RV6A but does not
have access to the RV-list .... yet.
>>>> I seek the wisdom of the RV-List in solving a dangerous (in my
opinion) problem. <<<<<
Problem: Loss of fuel pressure, engine sputter and HIGH pucker factor on
takeoff . The plane was airborne and he (+ another friend passenger) landed
safely. He had flown it earlier and stopped for a few minutes, so it was
still "warm" under the cowl.
Setup:
- RV6A with Lycoming 0-320 (150 HP) engine, carbureted ... nothing too
"unique" under the cowl.
- Fuel in use: AUTOGAS.
- Fuel from the selector is routed to the gascolator and from there to the
carburetor and to a primer (via a tee). These lines are wrapped in
insulating "hose". At the carburetor, there is a small return line to
inside the cockpit **just after** the output of the fuel selector. There is
a "restrainer" in the orafice of about .040" feeding this small copper
return line.
Theories: Vapor lock due to:
1. Orafice was too small (seemed clogged, so we opened it to .040") and
therefore there was virtually no return.
2. Exposed (small) copper return line in REALLY a heat exchanger and
instantly vaporizes any fuel that is in it unless the plane is flying, so
maybe it should be insulated.
3. The small line under the cowl should be LARGE so it can hold
(relatively) lots of fuel so as to never allow vaporization (its hard to
boil the ocean).
4. The small line under the cowl should be as small and short as possible
because you want to boil as little fuel as possible.
5. The small line inside the cockpit should be LARGE to facilitate
expansion and quicker cooling.
6. The small line inside the cockpit should be longer and coiled to
facilitate greater cooling.
....
As you can see, theories abound. Before we do something and attempt to fly
this machine again, it really would be nice to take advantage of the
collected wisdom here.
Sooooooo..
Has anyone out there SOLVED a similar problem *without* removal of the
gascolator and switching to AVGAS??
I know there has been much discussion about whether or not to have
gascolators. For this round of discussion, let's assume that my friend
really wants to keep the gascolator for the reasons stated in the list by
those that are happy with them.
Any assistance here would be appreciated as I thought I was about to
witness two friends have an unfortunate landing in trees and railroad
tracks ... not a happy thing. Also, one of these years, I hope to have a
VERY similar bird in the air.

Hi Hal,
Just heard a similar story about a RV-6 with a pop up canopy equipped
airplane. Seems the noise started at about 160 mph. The problem took a
long time to solve. Evidently the builder had attached a fiberglass strip
over the canopy joint at the rear window junction. The fiberglass had
worked loose where it was bonded to the canopy. It was basically
fluttering in flight when he got to 160 mph. It was rebonded and the
problem went away. Check any parts on or near your canopy. Also check to
make sure your root fairings with the rubber trim are tight against your
fuselage. You may be getting what we call in the airline industry as
"fillet buzz". The metal wing root fairings will start to vibrate on the
sides of the fuselage. Well good luck. I suggest not going too fast until
you solve the problem.

I got the wings on, ready to drill the rear spar attach points. (RV-4)
With the rear spar on wing lined up perfectly with spar carry through
(vertically) it came out to 1 deg incidence, as close as I can tell. If
I move the wing up approximately 1/4 inch to meet the 1/2 deg. +
incidence, the 5/16 hole I will drill will not have the required 5/8"
edge clearance. My question is this: If I leave it centered and drill
it so there is no question about the edge tolerance, can I adjust the
extra 1/2 deg. of positive incidence out with the tail? If I leave it 1
deg. positive, like it is, how will that affect the flying
characteristics? Is it something that will need to be adjusted? Thanks
for any help, I am going to drill them tomorrow. Also, measuring from
wingtip to common point on fuselage, one wing is 3/8" farther than the
other. I don't know what that equates to in degrees of sweep, but does
one of you experts out there know if this is something to be concerned
about? Boy, an 1/8" out, here or there really adds up when you need to
measure for something like this.

I just got off the phone with another applications engineer at Hartzell
propeller and confirmed what you have said about the M2YR hub. But it
seems we don't have all the information. Any extended hub propeller
Hartzell supplies with the exception of the HC-C2YK is limited to 3.8 g's.
Hartzell says even if you add 1 inch extension to a propeller it goes from
a 6 g propeller to a 3.8 g propeller no matter what the extension is all
the way up to 6 inch extensions. The propeller withstanding these loads is
not the issue, it will not fail, the failure will occur in the crankshaft
flange at or near the forward thrust bearing. The 200 hp engine in this
area has twice the wall thickness that the 180 hp engine. So here lies the
confusion. I would feel better about doing aerobatics in my 2 9/16"
extended hub prop and a 200 hp engine than a 180 with half the wall
thickness and a standard hub. It appears Hartzell has a blanket policy
that they've established yet to my engineering background seems a little
contradictory. I understand the gyroscopic loads somewhat on the engine.
Maybe someone else at Hartzell can help clarify this confusing policy they
have. It's possible it's just that they have'nt tested other combinations
at this particular time.

It's likely that the antenna you're working with is Stainless Steel. I'd

With all this talk about alternate antennas, I felt I just had to
contribute some thoughts that might save someone's transceiver output
section.
There is no reason that the aviation antennas should cost what they do.
However, if you are looking for affordable alternatives, you might take a
trip to your local HAM radio shop. There is an amateur band known as 2
meters that is very close to our band. It operates on 140 to 148 mhz. Most
of the antennas intended for two meter use will easily tune down to the
125mhz average that we require. Some have adjustable shafts while others
have a tuneable coil in the base. If you are building or installing
anything other than an off the shelf antenna, I would buy or borrow an
SWR/RF meter. Again, one intented for 2 meters will work fine on aviation
band. Concerning lengths... they are simply estimates. Once the coax is
run, secured and connected at both ends, the standing wave ratio should be
checked. If needed, the antenna can be trimmed to acheive the lowest ratio.
If you trim too much and the antenna can not be re-fabricated (if it's
glassed into a wing tip for example), a load will have to be added to bring
the ratio back down-start with a single turn of wire around a piece of 1/2"
wooden dowel, connect in series. Use heat shrink to protect the load after
the number of turns have been established, mount away from metal and as
close to the antenna as possible. A ground plane must exist or be
simulated. Follow your antenna plans closely or your antenna will have
unwanted directional qualities.
What will I use? Two lengths of 1/2" wide copper braid, laminated into the
wing tips.

The following information is about different wing tip designs, what works
and what is available for RV series airplanes. I'm not sure how much has
been discussed in this area to date, but I think now is the time to go over
it again because I have been personally involved in making the curved up
wing tips which many have seen in Sport Aviation April issue. It's begins
on page 50,"Computational Fluid Dynamics". I am presently flying with these
prototype wing tips and here are the real results.
It increased speeds by 2 mph. It increased directional stability in
turbulence considerably. Anyone know what it's like to ride in the back
seat of a V-tail Bonanza on a rough day. The RV has a tail wag or more
appropriately a dutch roll and yaw when the thermals abound, especially in
Texas and Arizona on a hot afternoon. These particular curved up tips solve
the wag and make it very stable in that arena. This added stability does
not affect roll rate. The airplane simply bounces up and down but does not
twist and turn anymore.
There has been another wing tip come out of Bakersfield,CA. Not sure who
is selling them exactly. I ran the flight test on John Harmons "Rocket"
because he had a set installed. We ran 2 tests with different wingtips
under the same conditions as we could get. Now keep in mind the Rocket
wing span has been reduced to 21 ft. 10 in and the top speed it is capable
of is much higher than a standard RV. Any additional wing span on the
Rocket will help top speed at higher altitudes. The test was run at 8500
ft. density altitude. During lunch after the flight I crunched all the
numbers. With many distractions due to the fact that there were probably
10 people wanting an answer on the wing tips and how well they did, I came
up with approximately 7.5 mph increase in speed. I later went home and
redid all the calculations and confirmed without a doubt 6 mph increase.
After several more wing tips of this type we're installed on an RV-6 and a
RV-4 and flight testing airplanes against each other we all came to the
conclusion without a doubt on the above airplanes we obtained 2 mph
increase. The difference compared to the "Rocket" is additional span would
help it more, especially when the air gets thin.
It doesn't appear the Bakersfield tips add much for stability, but it does
help speed slightly. They are available.
The wing tips that we're designed using the computer that are on my
airplane are not available for certain reasons. Knowing what we've learned
from a stock wing tip to the curved wing tip to the rounded tip is, the
best tip for the RV has yet to arrive. It will probably be a combination of
curved up tip with slight rounded leading edge with a slight increase in
span. Not on the drawing board yet.

it.
Then determine the required wire gauge based on wire point to point length
assuming a half to a volt drop from the supply to the appliance by using the
curves shown in AC 43.13-1A (I think). I got my copy out of a buddy's

You must calculate for the voltage drop and the conductor heat rise and
select the wire gauge that meets both criteria. If you absolutely cannot
otherwise locate this info on your own, e-mail me direct and I will get a
copy to you.
Select the breaker based on 135-165% (or the next available size up) of the
continuous maximum current for the appliance.
Examples:
1A sustained max draw=2A breaker
2A sustained max draw=3A breaker
2.5A sustained max draw=4A breaker
3A sustained max draw=5A breaker
3.5A sustained max draw=5A breaker
4A sustained max draw=7.5A breaker
5A sustained max draw=7.5A breaker
6A sustained max draw=10A breaker
7A sustained max draw=10A breaker
You get the idea.
You do not want to chose too low or you will experience nuisance trips. We
are really trying to protect the wiring, not the appliance.
Happy Building,

FWIW, my cleco injury was (is still) a paresthesia (numb area) of the hand

James,
With the vapor return line feeding back into the fuel source "just
after" the fuel selector, aren't you just pumping the vaporized fuel
right back into the fuel source? Why not dump it back into a tank
and eliminate any possibility of vapors in the source line (due to
returning
vapors).......

<< In Bob Nuckolls' book he talks about using the actual voltage rating of the
<< device in question to determine the allowable voltage drop. Is this procedure
<< not acceptable? This procedure would allow a much larger voltage drop than .7
<< volts. For example a system might be putting out 14.6 volts while a lamp was
<< rated for 13 volts. This would seem to allow a 1.6 volt drop.
The issue I was speaking to there was a special case wherein I cited examples
of landing lights characterized for operation at 13.0 volts. Obviously, for
a system that runs nominally 13.8 to 14.2 volts, the lamp would be quite happy
with a drop of .8 to 1.2 volts in the system's wiring. This figure falls
nicely
into the 5% allowable system losses figure I cited in my earlier posts. The
voltage RATINGS of various devices are NOT requirments but simply notification
to the system designer as to how the device was characterized . . . so many
lumins over so much pattern at 13.0 volts. Since 13.0 was the design point,
this tells a designer what to expect in the way of performance under nominal
system drops.
/Using a good digital voltmeter (or the manufacturer's specifications
/if available), determine what the appliance draws sustained worst
/case under load. If the appliance is a transmitter, measure the draw
/while transmitting. If the appliance is a lamp, measure the draw after
/it has stabilized at temperature. If it is a motor, put a sustained typical
/load on it.
Good advice . .
/Then determine the required wire gauge based on wire point to point length
/assuming a half to a volt drop from the supply to the appliance by using
/the curves shown in AC 43.13-1A (I think). I got my copy out of a buddy's
/Glasair Builder's Manual.
Also wire table I've published in the past few days. . .
/Select the breaker based on 135-165% (or the next available size up) of
/the continuous maximum current for the appliance.
Actually, breakers are selected according to wire size but maybe that's
splitting hairs. Picking the breaker according to applicance load is okay
too, especially if you've upsized a wire for voltage drop considerations
and left the breaker sized for the load, the trend is to protect bigger
wires with smaller breakers which is not a hazazrd.
/You do not want to chose too low or you will experience nuisance
/trips. We are really trying to protect the wiring, not the appliance.
Exactly!!!! Tens of thousands of Cessnas have 60 amp breakers protecting
their 60 amp alternator b-lead feeds . . . this breaker is DESIGNED to
nuisance trip. I complained about it when I worked there 30 years ago
but nobody cared. Now, that breaker causes more unhappy electrical surprises
for pilots than any other breaker installation in history. When in doubt,
upsize the wire and breaker a step. It never hurts to make it a tad bigger!

Bob . . .

Steve:
The HC-C2YK is a standard hub, not an extended hub.
And did you know the HC-M2YR-1BF/7666A-2 is approved for use on the
IO-360-A1B6,-A1B6D,-A1D6,-C1D6 With A max/min lenght of 76/73 and an rpm
restriction to avoid continuous use between 2100 and 2350rpm.
Now I know since it is on an experimental you can do anything you want, so
you can cut the blades down, but you take the risk of vibration problems.
And.....for those that may consider 3 bladed props, check the price for an
outright purchase. $$$$$$$$$$ And if you really want to go into sticker
shock check out an MT. I think it was over $13,000 4 years ago.
Makes the O-360 HC-C2YK on my 4 for look CHEAP. Man does it cost money to
go fast!!!!

Hi Shelby,
The current engines that Lancair 360's use are O-360 A1A 180 hp engines,
the same ones utilized in RV aircraft. These are non counterweighted
engines. Yes some people we're and are still using extended hub
propellers. Lance Neibauer of Lancair fame got together with Hartzell
after the incident and requested some vibration and stress tests be run
with the 0-360 engines and the earlier version of the "F" hub propeller.
Before the test this combination had never been tested or approved for
certified aircraft. The results were conclusive. The propeller was 200 %
over standard stress levels so Hartzell redesigned the propeller to it's
present configuration which is an approved combination for the 0-360 non
counterweighted engine.

Hi Mike,
The propeller you can use is a Hartzell HC-C3YR-1RF/F7282 3 blade propeller.
I talked to Paul Lowen of Lake Aero Styling (707) 263-0412 Ca. He quoted a
price of around $6100 dollars outright. Note: the propeller fits a Mooney.

You might check with MT in Germany. I know they make one that will work.
Lancair used to offer them in their options catalog. (They may still, I
have not seen one for several years).
Super prop, much lighter than the others.
If you ever walk the acro line at any airshow, MT is the only prop you will
see.

RE CAMERA HOLE CUTOUT
I tried this idea on a Continental powered C-172 (two exhaust pipes) many
years ago and learned the following, we had to do a severe sideslip to get
the engine exhaust away from the camera port.
Before cutting any holes have a good look at where the hole is in relation
to the engine exhaust stream. Heat from the exhaust stream will distort the
light waves and render a improperly placed camera port useless.
I am guessing that the exhaust flow from exhaust pipe(s) normally expands
about twenty/thirty degrees as it moves rearward and rotates slightly with
the propwash, it may pass under the passenger seat area.
When I get to my wings I plan to look into the feasability of a camera port
in the outboard wing bay and/or a quick change wingtip that will accomodate
my motor drive Nikon.
Has anyone out there mounted a motor drive camera on a RV?

Hi Rob,
Had a phone conversation with Rick Bauerman from Hartzell propeller
today. The HC-C2YK propellers (no extension) are used on "hard aerobatic
airplanes". Pitts Specials and the like. There is no "G" limitation on
these propellers. On occasion they do break. Hard aerobatics includes
snap rolls and spins which place the most load on the propeller and
crankshaft at the thrust bearing. Since Van's does not recommend doing
either snap rolls or spins this shouldn't cause a problem. Snap rolls
are also hard on control surfaces.
Hartzell only tests airplane that utilize the short hub for hard
aerobatics. The M2YR hub propeller was installed on normal category
airplanes which are classified by Federal Aviation Regulations as a 3.8 g
airplane. Utility category is 4.4 g's.
Full aerobatic is 6 g's. Obviously Hartzell can not test an extended hub
propeller if the airplane is the limit. So they test to the limit of the
airplane category.
Therefore if the M2YR hub is used on an IO-360 with the heavy crankshaft,
mild aerobatics should not be a problem. Keep in mind this airplane is
for sport aerobatics. If someone wants to do aerobatics get some quality
instruction before attempting anything aerobatic. We've put way too much
effort into building these things to throw it all away on a simple roll
and split S out the bottom with no altitude left. If some wants to do
hard aerobatics try a Pitts Special or Extra.
The B.A.C. "Holy cowl" was designed around an extended hub propeller for
better aerodynamics due to the longer nose. It also adds length to the
cooling inlets before the air gets to the plenum for better ram recovery.
I.E., much better cooling. This also enabled a longer intake box for
better ram recovery on induction air. Most factory airplanes have a loss
of 2 to 3 inches of manifold pressure due to poorly designed airboxes.
We have obtained 1" over ambient at cruise settings. What this equates
to is better power at all flight conditions. All this with ram-filtered
air. We are filtering air 100% of the time.
I think the 200 hp fuel injected Lycoming with 1 electronic ignition
combined with the new cowling and cooling plenum to be the most efficient
& economical as far a speed and fuel burn are concerned that one can put
in an RV-series plane. I'm sure I'll pick up some flak on that one.
If your looking to improve on a great airplane this is one way to
do it. If you want good looks, speed and efficiency or just want
something different on your RV this may be what your looking for.
Life's short-build fast

Steve,
Another question. 200 h.p. is more than Van recommends for the RV-3.
What airframe mods are necessary for that much power? I could see beefing up the
forward fuselage and firewall, thicker skins on the tail surfaces and balancing
the tail surfaces.
Thanks.
Cheryl:
Regarding your RV-3 questions suggest you talk with Alan Tolle or Van. Alan
built his RV-3 with the intention of installing our engine and achieving speeds
above those of stock RV-3 so made numerous mods such as thicker tail surfaces
and balancing. I don't remember that Alan did any firewall or forward fuselage
mods you mentioned. We have done none of these on our RV-4. Structure is
stock, firewall rearward on -4. But your concerns are very good-- Alan's
straight/level speeds are above VNE of stock RV-3. Normally most higher h.p.
engines above standard power are heavier. But our 200 h.p. engine weighs 265
pounds. This includes propeller reduction gear, fuel injection, starter,
alternator, ignition and water pump. So installed weight is approx. 40-plus
lighter than O-320. Bottom line: if you limit speeds our 200 h.p. engine
should not pose structural problems. But check with Alan regarding his airframe
mods and engine/airframe integration. His telephone: 209-447-1112. You may
also want to contact Claudio Tonnini. He is building RV-3 and has placed a
deposit for our rotary. He has been in contact with Alan. Also Stan Blanton
has ordered one for his RV6A--his tele: 806-799-4664. Stan also on RV list.
In your earlier note you asked recommended constant speed prop for our engine.
Ans: electric control. This probably means MT at this stage. We are looking
very hard to find an in-flight adjustable propeller with a more efficient,
thinner tip and less expensive.
We hope to see you at Copperstate. We will have forum there in addition to
Arlington before Oshkosh. Hope to have both RV-4 and Alan's RV-3 at
Copperstate.

Hi Rusty,
Yes the HC-C2YK is a standard hub. The intent here was to clarify what
Hartzell considers to be an aerobatic propeller, ie. no extension. The
HC-C2YK can be used for "hard aerobatics".
I am aware of the restriction imposed on one aircraft. There is also
another airplane which uses the same propeller and engine combination as
what you've stated and has no restriction.
Engine and propeller combinations are approved by Hartzell, Lycoming and
the airframe manufacturers on a specific airplane basis. Not all airplanes
have the same resonant vibrations. Here's a good question for you. Has
the RV series been tested for vibration using any of the propeller engine
combinations currently installed? The answer is no. We are all testing
what we have installed. Maybe some day Van's will embark on this task so
we will all know or have a better idea on how the creation we have
assembled reacts. That's why standards we're established in the airplane
industry. To give us some degree of comfort knowing it has gone thru some
sort of certification process. These are homebuilts.

Ive just read some discussion on props and aerobatics etc.
The comment was made that Vans does not recommend spinning or snap rolls
in the RV series aircraft.
Ive been saving towards the RV8 for some time now, and im getting a lot
closer to purchasing a large section of the kit ie emp, wing, fuse, tools etc.
I realize that they are a very clean aircraft and require absolute care and
attention in the down line.
>From what i read on the list i understand that they have a stronger wing
etc than a cessna 152 aerobat.
I most certainly can not afford the substancially higher price of a Pitts
or Extra or Giles 200 or any of the very dedicated aerobatic planes.
The cessna aerobat performs a lovely spin and a good clean snap roll.
But i would be very dissapointed to think that i would have to stay with
flying aeroclub ie hire cessna aerobats for the rest of my life.
Most of the ones ive flown have so much crap in them that falls to bits
during aeros, doors that suddenly fly open during slow rolls and to cap it
off that annoying high wing with its piss poor aerobatic visibility.
Its no wonder to me they are labeled spam cans.
Im head over heals in love with the RV8 but would be dissapointed to think
they cant be used for sportsman aeros with maybe a little intermediate as
well.
I have a friend here in Kiwiland who is really doing great in his RV4 with
intermediate aeros. What gives ?
Could I get some comment on exactly what the RV8 is safely able to perform
as far as aerobatic manouvers, also i see they are a -6 g
aircraft is this a usable -6g or is all the extra cost of inverted fuel oil
and injector system just going to be a waist of time and money.

stuff that comes in handy for those 'other' projects every once in a while.
At any rate, I shot off a quick email message on Sunday to the

needed along with my Plans Number and shipping address and then sat back to
see what would happen. Boy, was I pleasantly suprised! On Monday morning I
received a conformation email from Bill Benedict indicating that my order had

Most RV-6's that I am familiar with do not have a cooling problem, in

Why would you pick up flak if this is true?
In one of your earlier post you said that the 200 hp would increase
the speed of a RV-6 by 20-25 mph over a 180 hp, are you saying you
can cruise at 230 mph and burn less fuel? (based on my O-360 at
altitude full throttle and TAS of 206 mph) At what power settings are
you running your IO-360 to achieve this? What is your fuel burn? What
do all of your options weigh? What are you using as a gross weight?

Mike, You need to maintain the edge distance. Go ahead and set the edge
distance, check for the same distance from the tips to a common point on
the fuselage and that the leading edges of both wings are in a straight line
(ie not forward swept) and drill. Then set the Horizontal Stabalizer with
0.5 degree incidence. The fuselage may be flying downhill all the time,
but that is all. The RV-6/6A use a 1 degree incidence with the same wing
span, same wing area and same fuse length (almost). When checking
incidence, don't use just one area on the wing. Check several places along
the span of the wing. Even though it is built with no twist, there will be
a certain amount of wave in the wing. Probably the most effective area on
the wing for roll moment is about 2/3 of the span out from the fuselage. I
would give this area a little more credit when setting the incidence. Bill

The RV-4 and -8 are different in design from the -6/6A (just in case no one
noticed). The -4 and -8 are capable of spinning without qualification. The
-6/6A can be spun, however it has a spin characteristic that Van does not
feel comfortable with, so he does not recommend spins. There are several
people I know who spin their -6's without hesitation and have no problem
with it, but they limit the number of turns and perform a recovery before
the spin develops past the third turn. The wide bodies (6/6A) have a
characteristic of developing a tight high rate of spin some time after the
third turn that requires the pilot to move the stick to a neutral position,
apply opposite rudder and 'wait' for the recovery to occur. The -4 will
recover 'hands off', the -6/6A will unless the aircraft gets into the tight
spin. You can read more about this if you look back through the RVators.
Van wrote a detailed description about his testing, but I don't have it at
my fingertips. Snap rolls can be performed in an RV if you slow down to the
recommended entry speed. I look at a snap maneuver as something that was
developed to force a roll in an aircraft that would not perform a graceful
roll. Please don't flame me on this, it is said in jest. Until you enjoy
the rolls in an RV, my statement may seem unfair.

Once you fly aerobatics in an RV, even if you cannot perform a snap roll,
you will probably never want to get back in the aerobat. Well, maybe once,
but you will see how akward it feels next to the graceful handling
characteristic of an RV. I'm beginning to sound like a salesman, but the
more you fly 'em, the more you appreciate 'em, especially in the unusual
attitudes.

You are experiencing the results of the airframe flexing, and flexing means
moving, and moving means wearing. The RV does not flex as much because it
is more rigid. Also, since it flies around the basic manuvers instead of
falling through them, the airframe does not need to flap (yield) as much.

The only thing that 'gives' is confusing (no fault of yours) a suggestion on
-6/6A characteristics with the -4 and -8.

The spars are symetrical, so the loading can be symetrical. What is the -8
capable of performing? You can start by seeing what the -4 is capable of
performing! Van has not uncovered any characteristics that we want to limit
the aircraft on yet.
>Respectfully

>Warren Jones RV8 hopefull kiwiland
Does Van recommend any of our aircraft for 'hardcore aerobatics'? No! Does
he recommend sport aerobatics? You betcha! Is building an RV a waste of
money? I don't think so! Even if you don't like it (and there is probably
someone out there who has not liked it), you can sell it for more than you
have invested in the flying aircraft. Is that a waste of time and money?
Maybe a waste of time, but a lot of builders have just as much fun building
as a lot of us have in flying.
Hope this did not offend anyone, I just like to put little quips in to
bring a smile to the readers face. However, snap manuvers and spins just
become so unimportant when you have the capacity to perform aileron rolls,
barrel rolls, loops and all the combinations without having to dive to pick
up speed, and if you do not have the inverted 'stuff', these can all be
gracefully done in the positive domain (positive g's).
Today, I took one of our employees who is blind up for his first fright, I
mean flight in a small plane. With just positive manuvers, we did rolls
and loops with me describing where the horizon was all the time. He even
got a little stick time. Had no problem as long as we were in trim, but
when the plane accelerated and the pitch trim was out, we had one roller
coaster ride! This fellow has been blind since birth and has a remarkable
sense of presence. He got more sensation out of a 3.5g turn than he did out
of the roll and loop. By the way, we did all this in a -6A, even
prolonged stalls so he could experience the stall characteristic.

Steve, hi
I dimpled the cover for flat head #6 screws, but countersunk the E-615PP
for the screws and nutplate mounting rivets. I riveted the nutplates
on, and then countersink the screw holes as deeply as possible, right up
to the steel. This will make the covers fit almost flush.

Glen,
Now you have got my dander up. I would like to know on what basis you
make this claim? Have you flown an RV-6? All of the RVs are truly sweet
aerobatic mounts. They have light controls and quick, crisp response.
They have enough power to do any maneuver in the book from level, cruise
flight. The low angular inertia about every axis, in particular,
delights me. I could wish for more power and more roll rate, but then I
have never flown any airplane that I thought had too much power or too
much roll rate (including the F-15!) I am a 2500-hour military
instructor pilot. I know several retired fighter pilots, now flying
airliners, who fly RVs on the side because they handle like little
fighters. The first time I got a back-seat ride in an RV-4, I had to
have one. It is one of two airplanes I have ever flown that felt just
right from the moment I grabbed the stick.
>My question is......
>On an RV-6 without inverted systems, what kinds of maneuvers can be
>flown safely?
As in any airplane, you can fly any maneuver in the book (and any other
maneuver you can invent) as long as you stay within the capabilities of
the airplane and the pilot. Don't pull more than plus or minus six Gs,
don't exceed 210 mph, and without an inverted system, don't push neggies
until the engine quits. (I know that several guys race RVs around 230
mph, but I'll bet they aren't pulling any significant G.) The rest is
entirely up to you. All of the ex-military pilots I mentioned are flying
without inverted systems, and all do extensive aerobatics.
I am having Everett Hatch build me an O-360 of about 195 hp with fuel
injection and inverted fuel and oil. It is expensive, but fits well with
my intended purpose for the airplane. I intend more aerobatics,
formation, and dogfights than pure cruise flight. Just rationally
examine your purpose for the airplane, weigh the costs against the
benefits, and decide for yourself!

Subject: | RE: 3-bladed props |
From: | tcraig-stearman(at)juno.com (John T. Craig-Stearman) |
Don't be too quick to jump for a three-bladed prop.
As in all aircraft choices, a three-bladed propeller is a compromise. Be
aware that aerodynamic theory suggests a three-bladed prop will be less
efficient than a two-bladed prop of the same design. The reason is that
each blade operates in the wake of the previous blade. This effect
becomes more pronounced as you increase the number of blades. So why do
some airplanes, particularly those with more powerful engines, use three
(or more) blades? Remember that each propeller blade is a wing. As the
lift ( thrust) that the propeller must produce increases (with increased
power input), each blade operates closer to its maximum coefficient of
lift. Just as in sizing an aircraft wing, the designer must increase the
propeller "wing area" in order to reduce the blade loading. But now
another design factor comes into play. It may be impractical to simply
increase the blade length because of decreased propeller clearance from
the ground. The designer may opt to increase landing gear length, but
this in turn increases weight, cost, and complexity, particularly for
retractable-gear airplanes. A second option would be to increase the
area of each blade, as in the paddle blades on the C-130, P-51, and
SU-26. A third option would be to increase the number of propeller
blades.
I noted at least one post suggested that a three-bladed prop would lead
to more speed. This is not accurate. The design point that would
require a switch to three blades would be the low-speed, high-power
regime, most notably takeoff and aerobatic flight.
So before you buy a three-bladed prop, consider the costs and benefits.
A three-bladed prop will be more expensive, less efficient, and heavier
than a two-bladed prop of the same design. On the other hand, it will
run more smoothly, be able to handle higher power loads, and will just
look cooler. Look around at airports. I doubt that you will find many
three-bladed props on airplanes of 200 horsepower or less. An exception,
as in the case of the Lancair, would be airplanes with very short landing
gear.

Hi All,
I really tried to stay out of this one.
The three blade electric variable pitch Ivoprop Magnum prop has been
running very successfully on the Velocity with a Lycoming IO-360 of 200
Hp. Anyone notice if it was at Sun'n'Fun??
The Ivoprop three blade prop weighs the same as the fixed pitch Sensenich
Metal Prop for the O-320, and costs $1,960. It is a bolt on to ANY
Lycoming (as well as my dry flange LOM). And if you want to try the prop
as a two blade, just install it with two blades. (Of course, the two
blade prop is 5 pounds lighter than the three blade prop.)
Velocity convinced Ivo to build a high pitch version of the Magnum prop
for the Velocity. So far Ivo has only made a pusher version. They work
on pusher aircraft and LOM powered RV's. :-)
When I get my Dec. 96 annual completed with Lamb tires, Klaus wheel
pants, Tracy Saylor gear leg fairings, Matronics Fuelscan installed,
removable VS COM antenna, an electronic governor for my Ivoprop, I'll get
a chance to try out a set of the new blades.

Assuming a velocity of 150 mph, 2,700 rmp and a 3 blade prop; at 15
inches out from center, the blade turns 1/3 revolution in app. 1/15 of a

Subject: | Thoughts on COMM antennas |
I've been watching a thread on this subject. I think it started
when someone asked why that little stick of metal had to cost so
much money. There've been a number of responses most of which
contributed good and useable ideas but I'd like to summarize
some of what I've read and organized in no particlular way, add
a few thoughts of my own:
VHF comm antennas operate over a range of 118 to 135 MHz here
in the US . . . similar ranges elsewhere. The classic solution
to comm antennas on airplanes has been abasic, 1/4 wave, mono-
pole antenna using the aircraft skin as a ground-plane.The
antenna's radiating part has to be electrically connnected to
the coaxial feedline which carries signals between antenna and
transceiver.
The most durable materials for construction are the steels,
most popular of which is a stainless. Copper, brass and alluminum
have been suggested and used successfully for enclosed antennas
in composite structures but they are difficult to make live
on the outside. Non-ferrous materials work-harden and tend to
break off after some priod of time "waving in the breezes".
Electrical connections to copper and brass are easy . . solder
it. Aluminum and steels need soldered or solderless terminals
attached to the radiator with some sort of threaded fastener.
Many years ago, Cessna fabricated their own antennas by threading
the end of a 3/16" stainless rod, mounting the threaded end through
a two-piece, ceramic insulator in the cabin top and holding the
whole business in place with a nut inside and one outside. A third
nut attached the coax center conductor's crimped on terminal to the
base of the rod. Another terminal attached the coax shield to the
skin adjacent to the antenna base. The antenna would have worked
best if left straight but performance was only slightly degraded
by bending the rod aft to give it a rakish appearance.
This design suffered from the ususal problems. Things like this
stuck into the airstream like to shake rattle and roll. Skin
doublers were wont to crack around the hole where the insulator
came through. They leaked when it rained. They would also tend to
loosen up and if over tightened by a zealous mechanic, the ceramic
insulator would give it up with a sound like cracking ice.
None-the-less, the cost of fabrication and installation was
attractive and like most maufacturers then and since, cost
out-the-door was a MAJOR driver, not cost-of-ownership AFTER
it got out the door . . .
Aluminum and brass can be used for antenna rod material but
be prepared for periodic replacment. These materials work-harden
and break off regularly. Steel antennas can resonate and vibrate
in the wind and break too. I was riding shotgun with my sister
on a driving trip a few winters ago. We were getting some very
light precipitation and the OAT was about 29 degrees. I watched
in fasination as the am/fm antenna right out the window from me
gathered ice. As it's shape and mass changed, I watched it start
to "hum" . . it had a perfect full wave mode with a node right
in the middle that stood perfectly still. As the ice coating
grew, the amplitude of the hum grew too. My enjoyment of watching
the demonstration ended when the antenna just disappeared!
It broke cleanly from the fender mount right at the base.
People are generally unaware of the fact that MOST of an
antenna's good work happens in the first few inches off the
base. The design I just described had a substantial percentage
of it's working length INSIDE the cabin. The rod extended
through the cabin roof about an inch, an the coax cables I
saw had about another inch of exposed center conductor
hanging out from under the shield before a terminal was
installed. This material is PART of the antenna's overall
length at the base where the critter is trying to lauch
your signals into the ether . . . the part inside the
cabin was willing but crippled.
There was some mention of a radio shack automotive antenna
as a likely candidtate for vhf comm conversion. I bought a
12-1322 radio shack antenna for $10. First, the conducting
part is all one piece, not telescoping (good). The base is
designed for installation through a 7/8" hole with all the
work being accomplished from outside. All of the metals
appear to be stainless or plated except for the mounting
barrel which appears to be injection molded aluminum.
First, the coax feedline supplied with this antenna would
have to be discarded. If you cut it open you'll find a very
tiny center conductor designed to provide a low capacitance,
hi-impedance connection between antenna base and the input
stages of an automotive a.m. radio. This coax is unsuitable
for connecting the 50-ohm output of a transmitter to the
antenna. If you look inside the connector at the base of
the antenna, you'll see a stainless steel pin which is the
machined down butt of the antenna rod. The original connector
has a hard copper female sleeve that gets a fair grip on
this stub when the connector is engaged.
In am/fm radio service, this joint carries very tiny currents
in a receive-only mode. While you're transmitting, a 5 watt
transmitter will generate approx .3 amps in this joint. A
lot of degredation in this connection will go un-noticed in
am/fm applications while vhf comm transmission requires a
solid connection.
I think my approach would be to drill a piece of brass rod
for an interruption fit to the stub. Turn down the other
end for a solder post . . . .06 to .08" diameter. Or tap
it for 8-32 nut. Clamp the antenna rod in a vise and drive
the brass terminal down onto the stub.
When mounting this antenna, keep in mind that supporting
the whole thing on a skin area surrounding a 7/8" hole is
too much load on the material. A .06 or better doubler
should cover at least 4-6 square inches around the mounting
hole. Before installing the doubler on the skin, drill a
countersunk hole for a 6-32 or 8-32 flat head screw as close
to antenna base as possible and with head of screw against
the underside of the aircraft skin. Rivet the doubler to
the skin with generous sprinkling of flush rivets.
When the antenna is mounted, attach RG-58 coax center
conductor to antenna rod and shield braid to the ground
stud provided on the doubler. Use an SWR bridge or antenna
analyzer to measure the antenna's characteristics at
125 MHz. Use Dremmel with cut-off wheel to score the
antenna rod all around and then snap it off. When the
optimum length is achieved, use the hand grinder to
smooth and round the tip of the antenna rod.
Optimum performance dictates that the antenna be mounted
in a vertical plane. One respondant to this thread talked
about using "wingtip" antennas for comm . . . it was an
RV'er I think. I'm wondering if he is considering the
gamma-matched, monopoles offered by Bob Archer and described
in a variety of kit-type newsletters. Be advised that these
antennas are suitable only for vhf navigation (omni) because
they are horizontally polarized.
Another respondant suggested that amateur radio 2-meter
antennas may be cut down to a length compatable with VHF
comm operation. He did speak to the existance of "coils
and matching circuits" in the base but seemed to offer the
notion that an SWR meter doesn't lie when you trim the
aforementioned antenna to the length required to lower
the SWR at the frequency of interest.
Be advised that 2-meter (144-148 MHz) ham antennas are
generally 5/8 wavelength at the frequency of interest
and require a matching network in the base that really
clobbers the antenna's overall performance when trimmed
to operate in the 118-135 range. If you are considering
such a modification, take steps to bypass or remove any such
matching hardware before trimming. Just because the SWR can
be lowered to some satisfactory value doesn't make the antenna
work. A 50 ohm resistor has an SWR of 1:1 and radiates not
at all . . . it does get hot but we're not building coffee
warmers.
Without test equipment, it's impossible to optimize an antenna
in place. Without flying the antenna with test equipment -or-
taking the installation to an antenna test range, it's impossible
to put meaningul numbers on an antenna's performance. Be cautious
of suggested designs where individuals say, "it really works great!"
Consider that 95% of your communications occurs at within 10 miles
of the other station. A wet string hung out the window might be
said to "work great". The load it presents to your transmitter,
and the efficiency at which it covers the azimuth around your
ship with readable signals are all non-quantified in "works
great" evaluations. Further, you'll never know about the signals
you DIDN'T hear because of their position in some deep null of
the antenna pattern around your airplane.
If you enjoy the experimentation and have access to at least
rudimentary test equipment (I have an MFJ analyzer that I rent
out for such endeavors), then by all means go for it. If you're
trying to save money and wince at the idea of spending $50-100
for someone's production model but don't feel comfortable with
the experiment, then perhaps the purchased antenna is the better
deal . . . you can spend a LOT of time experimenting in the dark.
Be cautious also of no-name commercial offerings. Bob Archer's
antennas are well built and based on good engineering principals.
There are others with 'matching networks' and ferrite beads that
are questionable. Tiny, lumped matching networks may indeed
present a low SWR to the transmitter but they are very lossy.
Ferrite beads over the coaxial feedline to a dipole antenna
contribute so little to its performance that there's no value
in installing them.
Simply attaching the coax conductors to the center of a dipole
will produce useable peformance that is not improved by addition
of the ferrite beads.
For metal airplanes, a Dorn-Margolin or Antenna Specialist
monopole is about the best performing antenna you can build
or buy. It has a fairly generous base to spread loads, it's
been perfected over the years to provide reasonable service
life in 200 mph winds. It's electrical connection is made via
coax connector; ALL of the antenna's active length OUTSIDE
the airplane.
On composite ships, home-made or commercial monopole antennas
must have a metalic "ground plane" under them. Bob Archer has
some half-wave dipole offerings that do not require a ground plane.
My objective here is NOT to discourage experimentation -or-
to throw water on the do-it-yourself endeavor. Irrespective
of your reasons for deciding to buy or build, the outcome
can only improve if you arm yourself with knowlege. With
antennas, the devil is in the details.

Bob . . .

Alan, I am not sure how much spin testing Van has done on the -8(s). The
wider body is not as significant as the shape of the aft fuselage. The
rounder shape of the -4 and -8 with the round transition from side to bottom
make the difference. The -6/6A also has a radius at this intersection, but
not as large and has a larger flat surface. The cone on the -8 is very
close to the -4, in fact the first -8 has a -4 cone. Bill

When strapping a battery into the airplane . . . especially when it's

sensitive to this but it's good practice to minimize the number of
things that run into your body during unplanned arrivals with the
earth.

If I knew, I would comment. Van has never commented (that I can remember)
on the characteristics of the -3, however if it had an unusual
characteristic, he would have indicated it. The only thing that he
comments about the -3, is that it is the most enjoyable of his fleet to
fly. However, he has a -3, but is hanging in the rafters. The engine
developed cracks in the heads and being as practical as Van is, he removed
the engine and hung it up. It is not a good plane for demo flights!
There is a book entitled (I think the title is) "The Anatomy of a Spin"
where the spin is analyzed and the Grumman is cited several times as an
aircraft that you do not want to spin because of the design of the cone.
The RV-3 is a conventional design in this area, and I am sure that it spins
like a -4. Bill

The callout you mention is for the inboard end, actually the angle piece
that attaches the wing tank to the fuselage. It is thick enough to
countersink for flush rivets. At the outboard end, you would have to
dimple. I had the old plans with sheet 18 as well, which do not have
the tip reinforcements and call for AN470 rivets for the attach angle.
I decided to use them at both ends, and have not seen a fit problem.
Perhaps someone from Van's could comment on the reason for the change.

Subject: | Primer Fittings... |
Fellow RVrs...
My mid-time Lyc O360 is missing 2 of the primer fittings that srcew into
the top of the cylinder. These are the little jobs that have a goofy
1/8th tube fitting one side that has a small tapered brass bead that
slips over the tube and is then sandwiched between the fitting and the screw
on 'cap'. On the other end of the fitting there is there is a 1/8" pipe
thread with a 1" long mandrel that sticks into the cylinder head. In the
mandrel are two very small holes (maybe 1/32") that allows the fuel to flow
into the head. With that said, I have some questions that I hope you-all
can answer:
1) What is the part number for these?
2) Are these Lycoming or AN parts?
3) What is a good source for these babys?
4) Can I just use a 1/8" flared tube to 1/8" pipe fitting
instead of this special fitting?
5) Depending on the answer to question #4 above, what type of
fitting should I use to obtain the manifold pressure?
Cylinder #3's primer hole is a good place to pick up the
manifold pressure, right?
Instead of bringing the fuel into the cockpit for the traditional
primer pump, I have opted to keep that mess off of my feet and legs and got
thi nifty little electric valve that is in the ACS catalog. My plan is to
run a 1/8" tube from the top of the gascolator to the electric valve, and
then from the electric valve via 1/8" tubing array to the primer fittings.
My question is this; will the pressure from the boost pump (standard Van's
issue Facet job) be enough through the top port in the gascolator to get
fuel through the primer lines?
Finally, does it seem like a good idea to put a bulkhead AN fitting in the
firewall for the fuel line? A bushing alone just seems like a bad idea.
Thanks for all the help,

I was unable to find Plan 18A on my old set of plans but I think the area

Virtually any 1/8" fitting will do for the manifold pressure. You don't
have to restrict it like the primer fitting. Cylinder #3 will do fine.

I prime two cylinders using a setup exactly as you have described. There's
plenty of pressure to prime the cylinders. In fact, you only want to push
the contact switch for the primer solenoid for about 1/4 to 1/2 second;
you'll have plenty of prime.
One note. I wired the solenoid so that it could only be energized when the
boost pump was on (took the hot lead for the solenoid contact switch 'after'
the boost pump switch). My reasoning was that I would only need the
solenoid open when the boost pump was on anyway and this way there is no
chance that the solenoid could become energized inadvertantly. I'm not sure
if it would cause any real problem if it was energized but, hey, it seemed
safer to me.

I like the idea of the bulkhead fitting. Granted, you create two new

Yesterday I was driving past the Sacramento Executive airport and happened
to see an open hanger with two RV-6A's in view. Being a shy type I barged
right in and being RV'rs they were most cordial about it. I mentioned that
I had just seen the article in Sport Aviation about the aerodynamics study
of an RV-6 and asked if they'd read it. "Well, yes.........The airplane
that was the subject of the study is right behind you." Duuuuuuuuhhhh.
Yeah, I really read the article closely.
It's a shame that the article did not have a photo of the aircraft that
they modified because it is beautiful! The wing tips are kinda funky with
a flip-up of about 45 degrees to a sharp outer edge but the convex fillet
at the wing root definately looks well thought out. The most interesting
aspect though, was the cowl. Two, five inch circular cooling inlets with
rubber sleeves to connect them to an internal plenum whose top is a
close-fitting carbon fiber deck. The air inlet is much just barely below
the spinner and clears the prop by less than two inches. Inside the
intake is the spinner off a model airplane that directs air flow into a
plenum surrounding a conical airfilter. Access to the dip stick is through
a neat little door that is hinged inward and held shut with a magnet.
This is one neat airplane.
The best part is that he's going to be selling the cowls to any and all
comers! I was told that more info is available through the internet site
at Barnard.com but I've not been able to link up to it. If you happen to
spot it, please post the location.

. . . . You can run RG-58 to the

. . . . just run RG-58 out to

//to eliminate the possibility that it might short out against any exposed

One can certainly try this and if it functions to your satisfaction,
then why not? You should know that the input to a car radio's antenna
jack is NOT characterized for 50 Ohm coax like RG-58. In a recently
published article, I mentioned that if you cut open the cable supplied
with an automobile am/fm antenna, you'd find that the center conductor
is MUCH smaller with respect to the inside diameter of the braid than
you'll find with communications coaxes like RG-58. RG-58 has a capacitance
of about 30 pF per foot, the wire I just took off the Radio Shack antenna
measures about 12 pF per foot.
The input to a car radio is charactized for a very inefficient antenna
at the frequency of interest. It's so far from the ideal 1/4 wave value
that it becomes little more than a short probe which MUST operate into
a very high impedance receiver connection. This is why am radios for
cars have an "antenna trimmer" capacitor available from the outside
and a sticker that suggests what frequency it should be adjusted for
optimum reception. A 15 foot piece of RG-18 would have a capacitance
on the order of 400-450 pF . . . . MUCH higher than any ordinary
radio expects to see.
So, if you find that the suggested installations perform poorly, work
toward (1) reduction of the length of feedline and (2) use automotive
antenna cable assemblies if possible. None the less, the
31" whip is a MUCH better f.m. antenna at 100 MHz than the same antenna
is for a.m. at 1 MHz. If you don't care about the a.m. reception, then
I suspect that RG-58 will be okay. If the 31" wire is not standing away
from structure of the airplane, it might work better if shortened. A
look at it with an antenna analyzer would help you adjust it.

Aha, you are assuming that the effect of a propeller blade passing
through the air is restricted to just the actual path of the blade! Not
so. Have you ever seen photographs of air-to-air refueling in progress?
Note that the receiver is always at a significantly higher angle of
attack than the tanker, even when they are the same aircraft type. Both
airplanes are obviously traveling at the same speed. The receiver is
flying in the downwash generated by the tanker, even though the receiver
is at a lower altitude and not flying in precisely the same flight path.
Empirical testing of propellers (at least the data I saw some ten years
ago in aero classes) does show decreased propulsive efficiency as the
number of propeller blades increases.

Craig,
This was very close to problem #1 as I remember.
You can grind the side of one of your dimple dies (don't think about it,
just do it) to get better access. You can think carefully about where you
put holes (may not apply to pre-drilled kits). You can countersink if there
is enough metal.
One technique that I found helpful in various places was to get the
Pop-rivet dimple die set from Avery's and grind this down viciously (almost
to the edge of the dimple). These dies do a very ordinary job but after you
have used them you can "touch up" the dimple with your countersink which
will now remove very little metal but leave a nice recess for the skin
dimple to sit in.
It is worth having a good think about all the various techniques because you
will be using all of them in the next few years.

Well spotted! I commented on this to Avery's almost a year ago, but they
haven't seen fit to upgrade their toolkit. Like you I guess, I was not
happy to find that having spent a large sum on an "RV Starter Toolkit" I
needed to purchase yet another tool to do the second task in the project
:-(. It was just the first of several frustrations; accept it, and get on
with building. (In case anyone gets down on me for badmouthing Avery's:
they're a fine company to deal with, and I'd recommend them to anyone [and
no, Avery's don't pay me anything]:)

FWIW, I recommend you buy both a set of hand-squeezers and a vice-grip
dimpler. Here's my experience:
I made a vice-grip dimpling tool (you'll need a source of quality tool
steel for the dimples, a lathe, and welding equipment, or friends with
these). The results were adequate but not great. Later in the year, I
bought hand squeezers from Avery's to squeeze the 3/32" skin rivets... a
bonus is that the dimple dies that came with your C-frame tool also fit in
them. The dimples produced are better, and the hand squeezers are much
easier to use than the vice-grip dimplers (less muscle-power needed). For
tight spots (eg near the TE of control surface ribs) I still need the
vice-grip dimplers. You might want to consider vice-grip squeezers with
mounts to use the C-frame dimple dies (they're in Avery's latest catalogue)
instead of a dedicated vice-grip dimpler.

Craig, I assume you are trying to dimple the spar flange itself. You
should look at a countersink tool for this area. You will need this in
many areas in the future as well.
Good luck

Hi Larry,
When you order the finish kit for your airplane all you need to do is
request a deletion of the cowling upper and lower halves and upper cowling
inserts that Van's supplies. Retain all hinges required from Van's. It is
highly recommended you do so in writing to Van's. The current price
reduction from Van's on deleting the cowling, inserts and airscoop is
around $500.00 but please verify this amount with them. The B.A.C. cowling
has premolded induction and cooling air exits for less fiberglass work
later. There are 3 machined aluminum laminar flow inlet rings, 2 for
cooling air and 1 smaller one for induction air which are flow matched to
the cowling. The cost of the above from B.A.C is $925.00 + shipping and
handling. The cowling fits very well with little or no finish work
required and comes gel-coated white.

Craig, the squeezer is definately an invaluable tool for dimpling. I
don't have the "vice grip" dimpler and during my construction of the HS I
haven't needed it. I ordered the 3" yolk with my initial order and it's
worked great but does tend to flex a little with squeezing 1/8" rivets. I
recently ordered the 1 1/2" yolk and it's much better. The "C-Frame" tool
should also allow you to dimple the spar where the flange strips are
countersunk and need to attach. I've used the squeezer to do all the
dimpling on my HS and VS so far. Obviously the C-Frame tool will be needed
to dimple the skins.

I have seen several suggestions about this, and I am considering doing

I don't much care for the nylon hats that have screened on lettering, I
would probably go for a good quality wool or cotton-twill hat with

But in the process, it moved to the right 3/16 inch.
I could probably ignore it and consider it as within limits. Oddly, there are

Or I could fix it with a patch. My favorite idea is to fill the four holes in
the bars that are riveted to the HS with segments of AN bolt, swedged and staked

to ensure that the fillers remained in place.
Another option would be to double either these or the verticals.

This also enabled a longer intake box for better ram recovery on induction

I think the 200 hp fuel injected Lycoming with 1 electronic ignition
combined with the new cowling and cooling plenum to be the most
efficient & economical as far a speed and fuel burn are concerned that
one can put in an RV-series plane. I'm sure I'll pick up some flak on
that one.
If your looking to improve on a great airplane this is one way to do

Steve's reply
Jerry you have just convinced me thru your own words that RV's have too
much cooling. What this equates to is excess drag. You do not have an
optimized system. Is it perfect no? Does it work, yes. Cessna 150's and
Piper Cherokee systems work also, but does that necessarily make them
efficient? There is a large difference in speed between those airplanes
and RV's. The faster an airplane goes the smaller the inlets can be. We
have addressed this issue in the B.A.C "holy cowl". We have reduced the
cooling area inlets by 40% over stock configuration, yet I can still keep a
200 hp engine cool both in oil temperature and cylinder head temperatures.
Reducing the inlets this much decreases the amount of drag due to less
cooling air spilling over the outside of the cowling. You are getting
reverse flow out of the cowling with the stock inlets.
In reference to my quote on increasing the speed 20-25 mph by installing
200 hp has been taken out of context. If you read it carefully you will
notice that there we're other changes as well. Increasing engine power by
20H.P. in an RV will get you approximately 6 or 7 mph. There was also a
change from 180hp-wood prop to a 200 hp engine and constant speed. We
conducted a very accurate flight test last weekend with the following data.
Conditions:8500 ft. density, full throttle,2700 rpm, fuel flow 11.5 gph
with a true airspeed of 218 mph,(IAS of 195 mph)over a specified course.
There we're no special preparations on the airplane. I cruise at full
throttle 2450 rpm at 10,500 ft and burn 8 gph at a true airspeed of 205
mph. Now keep in mind this is an RV-6A nosedragger. These are honest
numbers. This was a true 75% power run.
I'm curious what other RV's weigh empty. Could we get a little response
back from the readers. List engine, propeller and type.
I think it's important that the individual building an RV consider the
aspects of the design in it's entirety and be comfortable with that
decision to own one.
The question as to why this was done is simple? Let's see how many of us
fit this category:
I just had to put a slick tire on my Schwinn stingray
The 57 Chevy Belair just begged for a four barrel and headers-don't forget
the glasspacks-the hood scoop just looks great
I wanted the red flames because it looked cool.
I really like that added horsepower for the high airports on a hot day.
As long as man has been around we all look to improve things. Need we ask
why? This is what we call progress. And if the RV can't be improved upon
I'll eat your hat.
Does Jerry have a bone stock, built to prints, airplane, come on Jerry you
changed something you did'nt like, did'nt you?
As far as exceeding mfg's design limits beg the question: How is VNE
(never exceed speed)established according to the FAR's? This is a question
you need to ask Dick Vangrunsven and ask for more clarification.
Hope everyone enjoys the interchange of ideas and information-no opinions here.

Hi Rob,
The B.A.C. "Holy cowl" consists of upper and lower halves. The lower half
has a integral induction air scoop and cooling air exit as part of the
cowling. No need to mold on the scoop later. The kit also has 3 machined
aluminum laminar flow inlet rings that are flow matched to the front end of
the fiberglass cowling. The cowling has been white gel-coated for minimal
preparation before painting. There are no changes necessary or differences
to cowling installation over the stock cowling. The cost for the above is
$925.00 + shipping and handling. Good luck with your airplane.

Subject: | Re: empenage dimpling |
Craig,
A couple of suggestions... If you are having a tough time dimpling
this area with the squeezer, you'll probably have a tough time setting
the rivets as well. Watch your edge distance, but don't put the holes
too close to the spar web or the HS-409 reinforcements.
The other tools I suggest:
Pop-rivet dimple die. I know Avery sells them and Cleveland probably
does, too. You'll need something like this if you want to dimple the
holes closest to the trailing edge bend of the control surfaces.
Avery and Cleveland sell dies with 1 side ground off (if you don't
want to grind down your only set). At some point, you WILL need to
get into a tight space. (Sounds like you are there now.) I also
ground the front off one of my squeezer yokes in order to get into
tighter spots.
I don't own the vice grip dimpler. Haven't missed it yet. There are
lots of ways to accomplish the same thing and most don't cost as much
as a specialized tool you use only a few times.
Good luck,

I'm midway through the wings now and have gotten by with a ground down
die and a pop rivet die set. Often when you really need a close quarters
tool, the nail for the pop rivet set can't be inserted in the die set.
In these cases, I have found both the cleco pliers and battery pliers to
be able to get in there and press the dies together. Cleco pliers also
work well for screwing in rod-end bearings. Be careful though, and pad
them to avoid damaging the bearings.

Hal,
I am not sure about the side to side tolerances but your suggested repair
does not sound as if it would comply with standard aircraft repair
practices. Those bolts are all that stand between you and eternity and there
has been an RV crash which seems to have related to non-standard practice in
the same area.
I would definitely speak to Van's about this and follow their repair advice
if they think the 3/16 lateral shift is significant.

I recently did some work on a work that required removing and replacing
some skin. The previous owner had smoothed all the rivet lines with a
bondo type material. It made it very hard to locate and drill some of
the rivets. Some of the screws in the fuel tank were covered, also. I
cannot get all the bondo (or whatever) out of the screw heads. Does
anyone know of a chemical or something else that will help clean out
these screw heads? This is a very good reason I will never smooth over
rivet lines on an airplane. You never know when a repair will be
necessary. I'm concerned about making a bigger mess if I have to drill
these screws out. Thanks to anyone who can offer advice.

If you do use pro-seal, be sure to use the low adhesion formulation
meeting MIL-S-8784B; that's CS3300, PS706 or PR1321 depending on the
manufacturer. That way the plates are easily removed if necessary.
I don't think much of sealing sheet metal surfaces with gaskets. If you
have thicker surfaces to which you can apply force without distortion,
then gaskets are OK. I'm using pro-seal.

plus shipping to your location. (If new, the same model of meter will
sell for about $375) The meter is in excellent shape, is extremly
accurate, but, I do not have any "slugs" to sell with it. The slug is
a plug like device that is inserted into the watt meter to make it
read correctly at the frequency you are interested in and at the
wattage you expect to measure. The slugs are a common item that can
be purchased from a Ham Radio store. They will run about $65 ea. You
should only need one for most aircraft use, (the same slug will work
in the 2m Ham Band also) but if other frequencies are of interest to
you the meter will work well no mater what frequency you are
interested in, you would just have to purchase the slug of choice for
the additional frequency. I could supply a list of stores that handle
such items, along with a chart of available slugs if requested.

I'd like to share my recent experience with blind rivets with the list.
Our local chapter's Technical Counselor inspected my RV6A project and
questioned the mandrel breakage in the Avex rivets, mainly the LP4-3s. It
seems he was accustomed to Cherry rivets which have requirements that the
mandrel break at or above the level of the rivet head.
I called Van's and they faxed me the Avex spec sheet which says the
mandrels break off beneath the rivet head. In fact, they deem this a
product advantage, as there is no rivet head shaving required.
I passed this along to the counselor as we have a half-dozen or more RVs in
our chapter.
I assume from the spec sheet that in the case of Avex rivets, the mandrel
contributes little to the shear strength. As a reality check, I inspected
a friend's 6AQB, and the factory-installed LP4-3s had mandrels that were
from 1/32 to 5/32 below the top of the rivet head, some well below the
shear plane.
Happy riveting!

Acetone will soften, if not remove lightweight Bondo body filler. You have
to keep the Bondo wet with it for a few minutes, and it helps to scuff the
surface of the patch first with fairly course sandpaper, like about 100
grit. I use a course ScotchBrite pad wet with the stuff. Wear rubber
gloves (latex will dissolve) and try to stay upwind of the fumes. Acetone
will also soften and ultimately erase epoxy and vinyl resins used in
fiberglass parts, so use some discretion.

Subject: | Re: ACK ELT installation |
Richard,
I installed the same ELT on my now flying RV-4.
Let me tell you what I did and how it worked out.
I put the main unit on the ledge in the baggage compartment over the
elevator bellcrank. This as it turned out not to be a good place for it
because it does move the C.G. aft and you definatly don't want that, it cuts
down on the passenger weight and baggabe weight as well. The batteries in
these things add up in weight and that was fairly far aft of C.G. A better
place for it on the 4 is over the batterty compartment as far foreward as
possible. It is a little agrivating when you go to get to your battery but
how often do you do that anyway.
I used the antenna they supplied and mounted it about 16" in front of the
verticle fin. It does not bend back as far as you might think. I have
pictures of it during flight and it bends back about 45 degrees at the tip. I
investigated other antennas but they all are the same length.
I mounted the indicator panel at the bottom right of my instrument panel.
Also don't forget to put the battery in the indicator panel like I did. The
remote indicator panel will not work without it and you cannot test or reset
your ELT without the battery. I hope this helps.

Hello Steve,
I talked to Bob Treuter before I started flying Ivoprop.
Even though I have flown the prototype Ivoprop Magnum prop (bad Idea to
fly any prototype prop!!);
I didn't add material to the outer third of the prop blade to "improve"
the prop.
I didn't run my engine at a critical RPM, such as, peak torque to
maximize impulse loading.
I didn't drill out the blade hub for large (stronger) bolts, which
removed the blade hub structure. (Similar to removing wing spar material
to reduce weight.)
Bob did.
There is a group of ULTRALIGHT pilots in Bob's area who feel comfortable
modifying manufacturers props. If something happens, they EXPECT the
prop manufacturer to replace their ULTRALIGHT. It has worked for them
before. Bob's still trying.
My opinion only, after talking to both Bob and Ivo, before I started
flying the Ivoprop MAGNUM prop.
BTW, the ULTRALIGHT Ivoprop and the MAGNUM prop are two totally different
props.
The ULTRALIGHT prop is normally flown on a two cycle engine.
The MAGNUM prop is normally run on a four cycle four cylinder engine.
This engine type has awful impulse loading into the prop, which is why
there has been a thread on the RV list about the 12 pound vibration
reducer.

The following crude ASCII drawing is the proper way to install the firewall

Acetone or MEK (Methyl-Ethyl-Ketone) will soften the Bondo, but won't
make it any easier to remove from the small crevices of a screw head.
Use the pointed tip of an Exacto razor knife, available in hobby
stores or the hobby area of department stores. Just scrape away thin
layers of Bondo until a screw driver fits. Then use new scews. :-)

I have been able to do all my dimpling either with the Avery tool or my
rivet squeezer, the exception being the screw dimples that I did with
the special dimpling tool available. I admit, however that the vise
grip tool would have been handy in places. The most important special
tools are the dies ground for clearance in tight places, IMHO.
You could modify the Avery tool by grinding the front end and arbor
block back so that you could dimple the flanges by putting the female
die in the arbor block and allowing the spar to hang below the tool.
However, it would weaken the tool for wing spar rivetting, and is not
something I would recommend in any case; it would be better to get one
of the special tools.

Subject: RV-List: Bondo
I recently did some work on a work that required removing and replacing
some skin. The previous owner had smoothed all the rivet lines with a
bondo type material. It made it very hard to locate and drill some of
the rivets. Some of the screws in the fuel tank were covered, also. I
cannot get all the bondo (or whatever) out of the screw heads. Does
anyone know of a chemical or something else that will help clean out
these screw heads? This is a very good reason I will never smooth over
rivet lines on an airplane. You never know when a repair will be
necessary. I'm concerned about making a bigger mess if I have to drill
these screws out. Thanks to anyone who can offer advice.

For all you who are beginning building, in addition to the other items
already mentioned you'll also need the #3 and #4 die sets that fit on a
finish nail (used as mandrel) that are used in conjunction with a pop
rivet tool, I think Wicks, Avery and Cleavland all sell them. In close
areas like at the aft end of rudder, aileron and elevator ribs you may
even need to bend the flange of the rib in order to install the die so a
dimple can be made. It's all part of learning to be creative, something
you'll need to be more of the farther you get into your project.

Could you please summarize the failures listed in the article for the list.
Ivo has been the subject of a lot of negative comments here and other places
in the past, but I have rarely seen specifics.
This is not intended as a flame. As a possible Ivo or ??? customer in the

obviously is working for Jim.
BTW, there were 2 Velocity factory demo aircraft at Chino this last

Richard,
The mechanic who balanced both my wood prop and the Sensenich FP metal
used a Chadwick machine. We bolted a sensor to the engine case and ran
wires from this to the unit in front of the airplane. Then, the prop is
"strobed" while the engine is running. He took some readings, we shut down
and he figured how much weight was needed and then we went through the
process again. After three runs, we were done. On the Sensenich, we ended
up using two AN4 bolts, four large AN4 washers, two small AN4 washers and
two AN4 365 nuts. These were placed side by side in two holes on the ring
gear. Weights could also be put on the rear spinner bulkhead. The
Sensenich prop was new and I had it static balanced when I took it to the
prop shop to have it re-pitched. It checked out fine on the static balance
but ran very rough on the airplane.
A friend, who has a RV-4 with conical mounts, ran the Sensencih on a short
flight and thought all of the needles on his gauges were going to fall off.
He cut his flight short because of the tremendous vibration.
Dynamic balancing smoothed the operation of both props considerably and I
highly recommend the practice.

<< I am getting ready to install the above referenced ELT in my -4. >>
I instatalled the same unit in my -4. I put the main unit under the right
floorboard just behind the spar and behind the right aileron control tube. I
put an access panel in the floorboard to service the unit (this location
won't work if you put in rear seat foot wells).
I ran the cable up the pilot seat back, and mounted the antenna on a 90
degree bracket attached to the upper part of the seat back on the right side.
I carved off part of the rubber antenna base to make it a tight fit against
the side of the seat back, to keep it out of the way of the passengers leg.
I then ran the antenna up the roll over structure to where the top of the
antenna is almost to the top of the roll structure, and I secured the
antenna to the roll structure with a tie wrap. This "hides" that ugly antenna
on the outside of the roll structure, where it is not visible at all when you
look in the cockpit from the left side of the plane.
I cannot comment on how well the antenna will transmit being tie wrapped on
the roll structure, but it is at least not an eyesore.

Guys,

"Sec. 91.207 Emergency locator transmitters.
(a) Except as provided in paragraphs (e) and (f) of this section, no person
may operate a U.S.-registered civil airplane unless--

What makes it approved? TSO-C91a {note the 'a'} does, and this is
reflected in the ELT manufacture's installation instructions.
In general, it is NOT approved with a different antenna, and NOT
approved without the instrument panel test control/indicator. If in doubt,
read the installation manual ...:^)
Your Tech. Counselor and DAR should spot this violation, and sorry

Hi Fellow Listers
I have just heard about electric AH's that are available from
decommissioned military aircraft (Noel, they are the Bosboks): some new,
some overhauled - but all with green (military) tags. They are priced at
about $200,00 each.
The catch, however, is that they are 28 volt instruments. Is it practical
to buy or design a power supply for the AH - it seems to me that at $200,00
there is room for spending something on a power supply.
A fellow builder (not on the list) says that he recalls some or other
warning by Bob Nuckolls about using non-12 volt instruments that on a 12
volt bus.
Any comments?

Subject: | How to prime lots of pieces at once? |
We received our RV6A kit (all of the kits, actually) today. It
arrived in the early afternoon, and by evening we were mostly done
with the inventory. Now I've got a question about priming.
We'd like to prime as many pieces at once as we can, before we start
building anything. Does anyone have advice as to how the part numbers
(currently ink-stamped on the aluminum) can be best retained after
priming?
Stamping the numbers into the aluminum is a possibility, but presents
dangers of its own. Another alternative would be to make a part
number map of the pieces as they lay on the painting stand and
re-write the numbers on top of the primer with a Sharpie pen after the
paint dries.
Has anyone else painted large numbers of parts at once? How did you
remember which part was which? Any advice is welcome! Thanks in
advance.

There are serious problems with connectivity to the matronics.com domain
currently. The email problems began Wednesday May 14 about 1am and are
currently still unresolved. I have been in contact with the ISP, Slipnet,
but I have basically received the run around. Current problems involve

problems to ftp.matronics.com FTP server. The later two problems began

videos and bitmaps on the matronics web page.
I am doing everything I can to motivate the ISP to resolve these issues.
However, they have been less than responsive so far. Perhaps if the almost

the Slipnet technical support (support(at)slipnet.net) and its president
Ted Glenwright (ted(at)slip.net) indicating how important these services are

RV and Zenith Listers -
Try as a might, I am still unable to motivate my ISP to resolve the
connectivity problems to the matronics.com domain. Currently, these
problems include:
-> No incoming email to the matronics.com domain (started Tue 5/13)
-> Most videos and graphics on the matronics.com web pages are
not accessable (reported Thrusday 5/8)
-> FTP connections to ftp.matronics.com do not work correctly
(reported Thrusday 5/8)
Fortunately, outgoing mail is still working allowing me to send messages out.
Any messages sent to the matronics.com domain between Tuesday 5/13 and
Thursday 5/15 were probably lost. Any messages sent to the matronics.com
domain after Thursday 5/15 are most likely in queue and will be delivered
normally when connectivity is finally restored.
I will continue to contact my ISP's technical support on a daily basis until
all of these problems are resolved. It seems incredible that a paying customer
such as Matronics would have to work so hard to have these problems resolved,
but alas that is support in the 90's I suppose...
Please do not post any messages to rv-list(at)matronics.com or
zenith-list(at)matronics.com until I post another message indicating that
connectivity has been completely restored.

Hello RVrs!
After a great deal of hair pulling, my ISP finally has the matronics.com
domain back online! I have tested the email pretty well and it seems to
be working normally again.
The problems with the Matronics Web and FTP servers have also been resolved.
The good news is that the new directory structure imposed by the ISP (and
consequently breaking most of my web pages and ftp server) have actually
been an improvment. I have spent most of last evening and tonight redoing
the web pages and ftp server to conform to the new layout and everything seems
to be working very well. The best news is that the archive volumes are
now available via 'http' hyperlinks instead of 'ftp' hyperlinks and should
work with everyone's browser (hyperlinks via ftp is broken in many browsers).
I have also been queueing any messages posted to the RV-List in the last
week (starting about last Thursday) and will repost these to the List
following this message. If you posted a message and don't see it, assume
that it hit the bit-bucket last week sometime during the bad part of the
outage.
Please feel free to start posting messages to rv-list(at)matronics.com as normal!
Also, please have a look at the matronics web pages, archive files, and
videos and let me know if you have any problems. The URL is:
