Default Feedback on wing wiring

Hi Folks, just hoping for some feedback before I start drilling holes in the ribs for my wing wiring. Just a quick idea of what I intend for the plane. VFR/IFR Capable, Dynon Avionics (Skyview) and AeroLEDs - Aerosun VX and Pulsar Lighting.

Left Wing - Dynon Heated AOA Pitot, Vans stall warning (As a backup), Pitot heat controller, Wingtip NAV Antenna and lighting as above.

Right Wing - Dynon autopilot servo and lighting as above.

Any input to things I may be have missed would sure be appreciated.

You might want a magnetometer out on the end of a wing. As well you might want OAT probe(s) somewhere on the wing (ie inspection panel).

Default Holes

If you go with the plumbing at the location planned, give some thought to how the plumbing will pass the bellcrank. I ran mine through but had to fab a bracket to hold the plumbing lines and keep them away from the bellcrank. Photos are on the "wing" page of my blog. I drew it up. If you want a copy of the drawing, send me an e-mail.

Also, once you decide, drill one with small pilot holes. Clamp an opposite rib to it and match drill. Use these two as masters to clamp and drill the others then enlarge all the holes to final dimension.

Default The bracket is a great idea

Yes Larry...the bracket is a great idea. I've looked at your blog and noticed that. PM sent to you with my email address. I would really appreciate the drawing

Thanks Mark...Exactly the kind of input I was hoping for. Now I have a bunch of reading to do on Magnetometer locations

I made a spreadsheet with all of the rib holes and which wires/tube runs where. It is very helpful to keep track of everything. I started using my spreadsheet when I was drilling the rib holes. I have an arrangement like you are proposing. Some holes are not needed in all of the ribs. For example the pitot is in the middle of the wing so those holes don't need to be placed in the outer ribs.

In my case there are lots of wires. OAT was mentioned. I have a couple of those. Stall warner if you are going to put it in is also missing from your drawing. Some people put a nav antenna in the wingtip so a coax would be reqired. Heated pitot power and status wires if you want one of those.

Garet,

One more thing to think about is the coax run for the nav antenna. Here is how I routed the coax around the the belcrank assembly. On the other wing think about the autopilot servo and other nav antenna if running dual nav/comms.

Default Diameter of Coax cable

Can those coax cables be routed in the main conduit with the lighting wiring?

Do you know the approximate diameter of the coax, or what size snap bushings are needed for the Nav/com antenna?

On the tip rib, on my RV-3B, the tooling holes are used to line up the ailerons. On the RV-7, that's shown on drawing 12A. I'd recommend keeping the area near those clear.

Also, as other people have suggested, figure out how you'll carry the various things past the aileron bell crank.

Garet,

The normal snap bushings sent in the wing kit will work for running the coax cable like I have in the picture. I ran mine outside the conduit because I heard that others have had interference on their com radios when the coax is too close to the wire runs for the lighting. I don't think it is too much of a problem with LED lights, but just wanted to play it safe.

This is an important tip. Don't enlarge the outboard end rib alignment holes. You can drill them later.
