Autopilot / Servo Wiring and Avionics Trays

 As part of my avionics package from Advanced, I purchased their pitch and roll servos.  All the servos come from the same manufacturer... also purchased the servo mounting tray from Glasair.

All of the brackets have been fit, fasteners drilled, and I added a few lightening holes in the tray itself.  While I was at it, I finished the left and right avionics trays that mount to the cage.  Lots of drilling and fitting nutplates.

All these were put through aluimiprep, alodyne, primed and painted.  The paint is PPG, and matches the grey of the cage.


Remote radio unit repositioned slightly due to cable length.

Everything dry fit.


Installed and wired.  I was SOOO careful to not mix up the wiring for the pitch and roll servos, and guess what - I cut them the wrong lengths.  So I de-pinned the connector and switched everything around.  


Left and right avionics trays are finished and nut plates installed.




The top picture is the left side tray (the IBBS is mounted under the tray). The next two pics are the right side tray.  I have not mounted the audio panel or Hall effect sensor yet... waiting for hardware.

I am going to need to raise the EMS and Audio Panel to clear nut plates underneath (they overlap each other slightly).

Handful of things to do before they are mounted - and actually will not be fully mounted until the firewall comes out.  2 holes need to be drilled in the forward tabs for the trays.

Next is the big tray that will hold the ACM, Skyview Network Hub, ECU, Boost Controller, Aux Box, and ADHRS.  I very quickly put it together to see if it was going to do what I wanted, with stuff I had in the shop.


Now that I think this is going to work, have gone back and finished drilling it, and making a few modifications, plus adding lightening holes.  Oh, and drilling for fasteners.... ugh.


After finishing, ready to mount.


Installed with most components present.


Lots of wiring still to do, but progress is definitely being made.
