Just a real off-chance guess: I heard someone else describe something
similar when their wing root fairing gasket was loose at the aft end and
banging the fuselage....

Thanks.
We think we had that too and Patty "lubricated" the rubber gasket and that
*different* noise seems to have gone away. It was more of a metal bang.
Seemed to ONLY occur during takeoff, presumbably as the wing was unloaded
from the flex of liftoff. It seems that if you make that fairing and gasket
fit REALLY snug on the ground, you will have the possibility of that
happening.
Keep those off-chance guesses coming!!

James:
I have an O-320 B2B 1961 vintage Narrow Deck installed in my airplane. It
was rebuilt to new specs before going into the RV. It has over 4,500 TT
since new. I converted it to Constant Speed prop at rebuild.
The only time I get popping sound is when the throttle is moved to idle at
speed. This would be backfiring.
I have the origional M-S carb. Think it is a MA3SPA or MA4SPA. No
rejetting on it. I was not able to get the idle mixture set properly till
around 40 hours when the engine was broke in.
Not sure what the sound is that you are hearing with power. The only thing
that I have heard with power on would be the rubber molding at the fuselage.
It needs to be glued on or have an EXTREMELY tight fit to keep it from
slapping the airplane.

I've seen this 'popping sound before on RV6. Not sure if its the same thing
as yours.
This one was very quiet but still noticeable. Turned out it was the bottom
skin
just aft of bulkhead 607. I'm not sure if that number is correct but its the
skin just aft of where
the elevator bell crank and bell crank rib are located. There is no
stiffeners or ribs on the floor
in that area. Problem was solved by gluing some rigid foam lengthwise. You
could also install a
couple stiffeners. Maybe try laying under the plane and pushing up on the
skin.

Wasn't there an issue of visibility of these lights against bright blue sky,
as they are the same approximate Kelvin temperature, and therefore not as
visible as the less intense but yellowish light from the tungsten bulb?

I've noticed similar and it is accentuated by the fact that the noise is just
sufficient to break the squelch on my intercom, which allows a large imrush
of ambient noise through the microphone into the headset, along with the
"pop." Open the squelch (or remove the headset) and the actual "pops" are
veery low intensity and don't have nearly the ringing quality that the
intercom artifact causes. I've learned to ignore this noise for over 4 years
now. Usually heard on climb-out at higher power settings.

We also placed rigid foam on the sides of the fuse around that area.
The RV was almost 'ring' free.
Good luck and let us know the problem and cure of its found. It will be a
good one for the archives.

There are some very good adhesive tapes available from auto body supply
shops that are used to glue on body mouldings and door guard strips. They
are double sided dense foam tape. They would be perfect for installing
stiffners in completed aircraft. You could experiment very easily by making
a stiffner out of some 025 scrap and sticking in that compartment. The key
to having the tape work properly is to have the aircraft skin, the stiffner,
and the tape at a very warm temperature BEFORE attempting to stick them
together.

I heard a similar noise when I took to $60,000 ride at
vans in their blue RV-6A. I heard it several times
during the flight and it was quite noticible. It
startled me but I was didn't ask what it was. You
might call Vans and ask if they know what causes that

| Subject: | infinity grip wiring |
--> RV-List message posted by: "Jim Lane" <jlane@crosscountybank.com>
The archives tell me how to wire the flap switch to relays and flap motor, but
I cannot find information on WHICH relays I need and how to wire them for ENGINE
START, FUEL PUMP, and STROBES.
Are you using the same type relays for these functions, and can you please help
me with wiring instructions or schematics showing how to wire these switches.
I am sure it would be of great help in wiring the stick grips if I could get it
right the first time.
I have the ACS keyed ignition switch and Van's wiring harness in the RV-8.
If I can get the stick grips installed, I should be finished with the wiring so
that I can rivet the top skin on and glass in the windshield. I really want to
fly this thing soon.
Thanks to all who are willing to share their knowledge and experience.

I would what to make sure you don't have a sticking valve, When a valve
hangs up and the engine fires on a partially open .valve it will blow into
the induction system if it is an intake or make that popping noise if it is
a exhaust valve Intake valves rarely give trouble as they are being cooled
by the intake mixture. I would do a differential after landing while it is
still hot just to make sure. This doesn't always pick it up as valve
sticking seems associated with conditions of flight.
I have had a wing fairing rubber seal come loose in flight, about eight
inches from the flap forward, it beats against the side of fuselage but this
is a continuous noise and the sound only changes with airspeed.

--> RV-List message posted by: "Karen and Robert Brown" <bkbrown@wmca.net>
If we could find out who makes the connectors for the RC airplane business, we
might be on to what Steve and I have been asking about, which is a plug for 6
or so conductors that could be used inside the control sticks (and as a trim wiring
disconnect). I have looked around, and I know that they are not Deans,
they are smaller than Deans by 50%.
I KNOW I have seen these on someone's RV site, but I was not smart enough to realize
how much trouble I would have finding them later on...The guy said he had
found them at a supplier to the RC industry and that they were a special made
item.
I'll continue searching and will let the list know if/when I find these plugs.

The Concorde RG-25 has M8 (.315") coarse female threads (with hex bolts) and
the Odyssey PC680 has M6 (.236") coarse female threads (with button head
screws).
When switching from the RG-25 to the PC680, I didn't change the .312" ID
terminal lugs on my battery cables to .250" ID. I just made some very short
metal spacers to fill in the annular gap from stainless tubing I had laying
around (.250" ID X .312" OD). Just make two of these about .030" shorter
than the cable terminal lug is thick. This then allows for switching back
and forth between different batteries in a pinch.

The method described above certainly seems like a workable scheme if you
want to postpone all wiring until the wings are attached to the fuse.
Since I wanted to complete all wiring while the plane was still in my
shop at home (with wings detached) I elected to use Molex-type
connectors at the wing roots (and yes, not only are they made out of
cheap looking plastic.....they came from Radio Shack!!) I also made
labels describing the connector pinouts and stuck them to the fuse
inside the wing roots in case I ever need to trace the wiring. This
meant I could apply voltage to the wiring system in the shop for a dress
rehearsal and know that the electrons were flowing the correct direction
at least as far as the wing roots. ;-)
Once the wings were in place at the hangar, it only took a minute to
join the connectors and the wiring was complete.
I have had no service problems with the connectors in the three+ years
and 440 hrs of service (I did solder the wires to the connector pins).
But...if problems do arise (and I don't expect them to) in a couple of
minutes I can remove a few screws, lift the wing root fairing and have
access to the connectors. For me the connectors worked very nicely.

I LOVE butt splices! I have no idea how many are in my plane but I find
them invaluable for the tinkering with the wiring I have been more or
less constantly doing since the plane has been flying. I use a high
quality crimping tool from AeroElectric Connections, give each wire a
hefty tug following the crimp (never had one to fail) and move on to the
next task in a fraction of the time it would take to finish a soldered
joint (and I possess a military certification for soldering).
So many ways to accomplish the same tasks! We all have to evaluate our
skill level, capacity for patience, desire to obsess over details, and
go with what works for us as we complete our projects.

| Subject: | Rv8 wing conduit routing---and wiring connectors |
--> RV-List message posted by: "Van Artsdalen, Scott" <svanarts@unionsafe.com>
FWIW,
I delayed wing wiring until the wings were mated permanently. Had the
plastic conduit in the wings. No connectors at the root. I didn't
anticipate removing the wings again either. Works great. First flight
should be in a few weeks.

The method described above certainly seems like a workable scheme if you
want to postpone all wiring until the wings are attached to the fuse.
Since I wanted to complete all wiring while the plane was still in my
shop at home (with wings detached) I elected to use Molex-type
connectors at the wing roots (and yes, not only are they made out of
cheap looking plastic.....they came from Radio Shack!!) I also made
labels describing the connector pinouts and stuck them to the fuse
inside the wing roots in case I ever need to trace the wiring. This
meant I could apply voltage to the wiring system in the shop for a dress
rehearsal and know that the electrons were flowing the correct direction
at least as far as the wing roots. ;-)
Once the wings were in place at the hangar, it only took a minute to
join the connectors and the wiring was complete.
I have had no service problems with the connectors in the three+ years
and 440 hrs of service (I did solder the wires to the connector pins).
But...if problems do arise (and I don't expect them to) in a couple of
minutes I can remove a few screws, lift the wing root fairing and have
access to the connectors. For me the connectors worked very nicely.

I LOVE butt splices! I have no idea how many are in my plane but I find
them invaluable for the tinkering with the wiring I have been more or
less constantly doing since the plane has been flying. I use a high
quality crimping tool from AeroElectric Connections, give each wire a
hefty tug following the crimp (never had one to fail) and move on to the
next task in a fraction of the time it would take to finish a soldered
joint (and I possess a military certification for soldering).
So many ways to accomplish the same tasks! We all have to evaluate our
skill level, capacity for patience, desire to obsess over details, and
go with what works for us as we complete our projects.
And you will LOVE the final product! :-)

Hi Guys,
Just received a couple of photos from Jim Norman of his completed (and
recently flying) airplane.
Take a look at a beautiful airplane.

James,
A strange noise in my RV-8 turned out to be about 8-10 inches of the rubber
sealing strip at the wing root fairing that had come loose and would flap in
the wind occasionally.

"DigiKey" will have them for sure and they give good service on small orders.
They have a catalog and also a web site with an electronic catalog for internet

Are you using an electronic ignition in place of one of the mags??
More on the reason later.

We seemed to have the "oil can" sound and Patty deduced that that was from
the wing root intersection fairing being overly snug with the rubber gasket.
She applied some type of lubricant to the rubber so it could slip it it was
really pressed and that seemed to have gone away.
This sound is yet a different one.
Thanks though.

Thanks, Eustace.
I don't think it is the rubber seal.
Don't know if it is a sticking valve.
More later ....

> The archives tell me how to wire the flap switch to relays and flap

The reason to use two relays on the flaps is required because of the single
throw switches supplied with the Infinity grips. Unfortunately, Paul Besings
website and Infinity Aerospace's website don't seem to be working right this
minute or I would provide you the links. The relays are very nice ones
available from Radio Shack.

The other functions can be covered by regular relays of which good quality

Up to about a year ago I was on the Matronics AeroElectric List. It was
being monitored by this electrical engineer named Bob Nuckolls. He would
take the time to answer every electric question that came along. I even
talked to him on the phone a couple of times and he always helped out. I
don't know if he is still over there but you might want to sit on that List
untill you're done your wiring. I plan on getting back on when I finish up
my panel and wire my engine. Head over to
http://www.matronics.com/subscription/
and hop on.

| Subject: | UPDATE ... Random (engine??) "POP" |
--> RV-List message posted by: "James E. Clark" <jclark@conterra.com>
First, thanks to the many listers who have responded both "on-list" and
"off-list".
There have been several things suggested as the potential culprit so I think
I should give a status on many of them.
1. Rubber seal at wing root (either causing oil canning or flapping in the
breeze)...
We have had that problem already (oil canning) and think it has been solved.
For those unaware, it seems if you make the fairing and rubber gasket fit
VERY snug against the fuselage, you can induce oilcanning when the wing
loads (bends) up on takeoff and unloads (bends) down when you ease off the
back pressure. You can either trim the fairing some more or make it so the
rubber will give a little ... we did the latter and it seems to work. Our
sound in question is a *different* one now.
2. Sticky valve ...
Don't know about that one. It is not the leading candidate yet.
3. Leaky induction ...
Same as #2 above. Visually, did not find anything amiss. We did find a
little "blow-by" on one exhaust ... bolts needed re-tightening.
4. Bottom skin, aft bulkhead ...
Same as #2 above
5. Exhaust stack hitting fuselage ...
We looked into that and all is snug. No signs of it hitting the fuselage.
Also the sound is more of a "pop" than a vibration.
6. Electronic ignition "misfire" ...
--->> CURRENT NUMBER ONE CANDIDATE!
I had a talk with Jeff Rose, and with great precision and logic, he
proceeded to explain what ***COULD*** be happening. Jeff thinks (with "80%
certainty") that what we have here is arcing in one of the spark plug wires
driven by the electronic ignition. He explained that it is possible that one
of the connections is just loose enough to cause this when the engine is
UNDER LOAD (climb out, pull up etc.) and the pressure inside the
cylinder/chamber is high enough to cause INCREASED RESISTANCE across the
plug. With a "loose" connection, there would be an arc as opposed to a clean
firing (path of least resistance) and the missing of ONE firing would make a
sound that would be enough to scare you.
He suggested removing the wires and inspecting inside the plugs looking for
the tell-tale sign of a black spot (carbon from the arcing). I did and 'lo
and behold there was some in the plug where the wire had come loose before
and I had replaced it!! I also found some (a lot less) in another cyclinder.
In **THEORY** maybe this could even explain why there were multiple, I
guess.
The wire was cut and the spring at the end re-inserted per Jeff's
instructions. The engine was started to make sure I did not make matters
worse.
Other than that, we have **NOT** tested this yet and the problem did NOT
manifest itself on the ground (per Jeff, the engine does not have enough
load to drive the pressure high enough to cause the arcing in that
situation.)
It was late when we got most of it done and I *hope* the weather is good
enough to do a flight test tommorrow.
PLEASE NOTE: This may turn out to NOT be the problem. It is number one on
the list for me (actually it was 2nd in the things I originally listed
-) )because Jeff seemed to be so informed about exactly why and how this
**COULD** be the problem. He was so thorough in explaining all of the
"why's" and "how come's" that we are focussing on this first.
**IF** this is the problem, please note that it is NOT a problem of the
electronic ignition itself, but of the connector at the end of the plug wire
and its construction. Even if it is not, I would love to kow if anyone with
the ElectroAir system has any tips on making those ends a little more
substantial (this is with aircraft plugs, NOT automotive plugs).
Once this is tested, I will let the list know what happened and if needed,
proceed down the list of other possibilities.
Keep those ideas coming .... just in case. :-)
Again, thanks to all!!
James

> If we could find out who makes the connectors for the RC airplane

that they are not Deans, they are smaller than Deans by 50%.

Bob,
Try asking this guy
terminal@rea-alp.com
He runs Terminal Town which is at
http://www.terminaltown.com/
Also try asking Bob Nuckolls at
http://www.aeroelectric.com/bob.nuckolls
or
http://216.55.140.222/bob.nuckolls/
I would like to hear the results. I ended up with a fairly large Molex
connector under the passenger seat. I'm assured it will work but for some
reason I'm not impressed with the overall quality.
The super small one probably couldn't handle any serious current though. It
would be alot of extra work and complexity to have to use a relay for every
function of the Infinity stick grip. For example I have a pair of quad red
LED map lights behind my head that will run right off the switch. Real easy
and handy that way.
