MOUNTING THE GSA 28
I really enjoyed sealing up the left wing. It has a finished look to it that I really enjoy. Now it is time to move on to wiring the right wing, adding the autopilot roll servo, and getting it ready to rivet. In the same fashion as the left wing, I dimpled all of the skins and ribs. There really is not much to talk about here. At this point, it has become pretty straightforward.
The right wing is a bit different from the left wing. In the left wing, I ran lines for the pitot/AOA mast. The right wing will house a Garmin GSA 28 autopilot roll servo. I purchased the mounting brackets from Aircraft Spruce. The most detailed instructions for installing come from Garmin. Here is a link to the main page for the G3X Touch manuals. Since they update frequently, this is hopefully a better link to offer. I found the instructions excellent. They began in Section 18.5 and offered detailed mechanical drawings highlighting the install process. Well done Garmin.
This picture is of the final product. The GSA 28 mounted in nicely and it is easy to see how the backshell assembly will plug right in.
WIRING THE RIGHT WING
The right wing will also have the ZipTip wingtip (which should be abundantly obvious I suppose…). Pulling the same set of wires a second time is definitely easier and went smoothly. Additionally, I pulled wires to the GSA 28. The pinout for the backshell is once again in the Garmin G3X Manual. I have decided against having aileron trim. I’ve flown a few Pipers that had it and I found myself messing with it more than it was helping me with anything.
Once everything was pulled through it was a matter of tidying up. I want a nice, clean-looking wire run. Now I am off to do some more research and work on this whole CAN BUS idea for wiring up the various LRUs on the Garmin system. More to come!
