Just the tiniest bit of crud, but nowhere near as much as I expected. I guess Corona's fuel has been pretty darn clean lately.
Here's an attempt at a closer view of the crud. It's negligible.
Clean as a whistle. Back in it goes until the annual condition inspection in March (or whenever I do it before then).
Building the Digitrak wiring harness was trivial. Power, ground, dimmer, GPS serial data, and then seven wires out to the servo -- which I accomplished via 4-conductor and 3-conductor insulated bundles.
TruTrak provides a D-sub connector with solder cups. I put that in the box and used one with crimp sockets instead. I want to be able to pull these pins/sockets out easily if I ever upgrade the autopilot and need to re-wire.
When I built the plane, I "pre-wired" a 3-circuit MATE-N-LOK under the panel that already had power, ground, and GPSS serial data wired from the GPS. So now all I had to do, instead of having to run those wires to their sources, was just build a little 3-circuit male connector. Easy.
I spent a couple of hours getting the servo wiring run and tidied up. This was the bulk of the effort. Had I thought ahead, I might have considered running servo wiring when I built the plane. It would have saved a lot of aggravation now...but it would have added dead weight, etc. It's your call, but I think it makes a lot of sense to wire for autopilot servos up front, even if you don't install them initially.
I ran the 3- and 4-conductor wires through the snap bushings on the cover support ribs -- where brake lines would go on a nosewheeler. Another case where building the taildragger is easier...you've got more room for wires and less tubing going through here.
The servo wires punch through the spar in an existing hole for antenna wiring and such, and then exit the side of the fuselage through a snap bushing that I had left in place for "future expansion."
From there they hook up and forward to the location where I ran the pitot tubing originally (before I had a clue).
They run right down the center of the wing spar through those snap bushings.
Got stuff to do this afternoon, will have to finish later...
