Autopilot install - Part II

So after a long day in the hangar on Saturday, I spent some time on Monday poking around on the Internet looking at other TTAP installs on RV's. That is when I noticed that my install was slightly different than the other RV-9's I saw. Turns out, the drawings that TT sent with my AP were for the RV-7/10 (which I had noticed) but there are different drawings for the RV-9! I downloaded and printed the right drawings from TT's site. I also called TT to ask them about my pitch servo installation bracket. Zach said it should be fine to shorten the pushrod tube as long as there isn't any interference. I also asked him about how the washers are supposed to be used. See my post here. Told them they needed to update their drawings to reflect this information.

So back out to the airport I went after work. I disconnected and then reconnected the wing servo pushrod per the RV-9 drawings. :-) I also installed the pitot/static fittings and tubing to the new control head. The fitting locations are then ADI-II are in a different location than on the plain ADI, so it required new tubing.

Tonight I'll head back out and work on the pitch servo installation. Going to drag Sandi out with me to help double-check my wiring by doing continuity checks from each end of the wires.
