 |
|
I need suggestions as to the best location and method to route the wiring
from the rear fuselage up to the panel/subpanel area in my RV-7 project. I
have the following equipment wiring that needs to be handled:
--AFS magnetometer wires,
--AP Pitch Servo,
--ELT panel switch,
--strobe power supply leads,
--electric elevator trim,
--GPS antenna coax,
--marker beacon antenna coax.
Are most builders routing their rear fuselage wiring in the center elevator
push-tube channel? If so, should one use corrugated plastic conduit or
simply bundles and snap bushings?
Any suggestions/photos would be appreciated.
Thanks!

Wade,
Go to the Aviation Trailer department of Northern Tool, Harbor Freight, Tractor Supply, etc. and check out he weatherproof connectors for trailer lighting. They are polarized in a manor to prevent improper connection. They are sturdy. They come in a number of sizes with different wire counts. Color coded wires. Heavy wire. And they work great. Check them out. I use them for the wing electrical connections in my Europa which has removable wings.
As for the tail wiring, I really can't help there as you are dealing with a metal aircraft and my Europa is composite. Hopefully another RVer will come up with a suitable solution.
Check six,
Bob Borger

I ran two conduits before floor was fastened down. Wish I had run 4. Of
course I am all electric with batteries in tail because of Subaru on the
firewall. I put transponder antenna and couple of wires to auto pitch trim
"controller" down center channel. Not a whole lot of room there.

Hi Wade-
I'm building an -8 and am not intimate with the details of a -7, but I
would suggest that although the odds of a properly secured wiring bundle
somehow fouling the elevator controls might be small, they are zero if they
are routed elsewhere. What I have done is to install corrugated conduit
under the floorboards (and elsewhere). I have left a length of sturdy
string in each conduit that is something over twice the length of the
conduit, and the string has a toggle at each end made of dowel that is long
enough to keep the end of the string from disappearing into the conduit. I
use the string as a fish tape, and once I am sure I won't be adding more
wires to the bundle, I can remove the string. I suspect I'll leave it in
there permanently, though, as much for 'polar bear repellant' as anything
else.
Getting the string into the conduit is easy. Put an inch and a half or two
inches of dowel on the end of the string and use a blow gun. Just be sure
to hang on to the loose end of the string, as this technique works waaaayy
better than I'd ever have expected...

Wade,
I used PVC conduit throughout my RV for routing wiring and other things. I chose PVC because 1) it is smooth on the inside which makes pushing/pulling things through easier, 2) it is cheap 3) it protects the wiring and tubing well from daily abrasiveness and 4) it is easy to make an entry/exit hole wherever needed. I did not used connectors at the wing root for wiring because I expect to never remove the wings. Should I need to remove the wings, I can then add in connectors if desired. I ran PVC along the fuselage sides under the consoles for passing wiring front to back and through the wings to pass wiring out to the tips. It worked fine for me - although a few times I could have used larger diameter tubing.
You can se some of what I did at http://www.rv-8a.net/2006.htm and scroll down to April.
