Wing wiring progress

We made some progress in wiring the wing, in preparation for riveting the outboard wing skins.

We added holes to the conduits, with bushings for the wires to come out:

Conduit hole with bushing
This was done with a heat gun with a circular tip, for simplicity - melting away the hole seems to be much more reliable in that it's unlikely that a cut will propagate and open up the conduit.

Most holes were added near inspection panels (since that's where most equipment will be), except for the pitot heat controller box, which sits adjacent to one of those areas:


I was excited to pick a decent color scheme for the wiring, since so many colors are available, until I found out that most of the wires I'll end up running are shielded, and those are always white (with fixed colors for the inner conductors) :/

Given this, I decided to follow the Aveo colors for the wingtip wires (with one addition - using black/yellow for one of the returns). This is for the right wing, where the servos are - the left wing has antennas and thus gets the shielded equivalent.


We then started running wires:

Autopilot-to-trim-servo wires going through the conduit
For the pitot heat controller, I used 12AWG shielded cable (M27500-12TG2T14) - shielded so the magnetometer and NAV antenna can go on the wingtip without as much interference, and added connectors:

I then ran the controller box wire to the bay where the pitot tube actually is, through the aft conduit Clickbond attachments:

There'll be a lot more wiring to come, but most of that can be done with the wings closed - the main exception was the pitot heat, which will be much harder to access.

Time lapse:


Total wing ribs time: 16.3h

  1. I do not know the -10 wing in detail, but it looks to me that it will be very hard to get access to the pitot control unit after the skin is riveted on.
    On my -7 I tested acces with skins clecoed on and I had to move it.
