Wing root pictures

[JDA_BTR]

Thinking through the wing wiring and don't know how the wing root ties into the fuselage for wiring purposes. Does anyone have some pictures that show the wing root at the fuselage?

Dudley,

Dudley,

If you're interested in an electrical disconnect at the wing root, this one by Mouser is pretty solid. For my RV-8, I used it for my nav, strobe, landing, and taxi lights:





Part Numbers:
Sockets: 571-206705-3; 571-206708-1
Pins: 571-66101-4; 571-66099-4




Hope this helps. Enjoy the wire-up!

That is part of my question. Am I going to make new holes in the fuse to pass the wires or are there already places for it? Was thinking of deutsch connectors and not a bulkhead mount but could do a bulkhead if that makes sense.

It will be a substantial amount of wire. I'll have the a/p servo and a GMU-11 in the right wing, and the OAT probe probably in the left, in addition to strobes and lights. No electric roll trim going manual for that.

There's no preexisting hole for passing the wiring into the fuselage, or if there is I'm way too dumb to identify it. I'm not flying yet but my wing conduit (1/2" PEX tubing) will protrude into the fuselage under the seat floors. Connections will be along the lines of handshake connectors or d-sub pins depending on wire gauge.

Dudley,

I think you'll find that there is plenty of latitude for your penetration decisions on the RV-8. The quick-disconnects that I use are for lighting only, but I made additional penetrations for such things as pitot-tube lines, a remote magnetometer, and a temperature sensor mounted on the pax NACA vent located under the right wing. Just as you must drill for fuel lines, the same is true for all wiring decisions.

Here is a shot of one area just after using a rubber mallet to pound the living snot out of the NAS wing attach bolts on the right side. You will also notice that when the floors were re-installed, I was forced to burnish the quick disconnect because of interference with the passenger footwells. Live and learn . . .



Here, you can see from the outside a separate penetration I made for the Dynon remote magnetometer:



Let me know if you have any more questions. With as much latitude as we have for the wing root area, I'm sure many other builders (like Philip above) have made better decisions than mine.

Best wishes . . .

I also used Deutsch DT and DTM connectors at the wingroot. I have two temp. sensors, GMU-11, Roll Servo, Taxi-, Landing-, Strobe- and Navlights as well as a archer antenna in the wingtip. I have them fixed at the fuselage and free at the wing.

And as Scott mentioned, be careful with the passenger footwells.. I had to reposition my BNC connector for the Archer NAV antenna!

I just used longer wire - no connectors. Kept the wire coiled up in the fuse until the wings were attached, and then just pushed them through the conduit.

Same here-if wings ever have to come off, I'll cut the wires.

I also thought about installing a connector.
Decided against, I wired the wings with extra lenghts to factor the fuselage once mated.
I'll cut them if needed...
