The paint cured on the parts I painted yesterday after being in the warm house overnight. This morning I riveted together the electric aileron trim module. I was able to squeeze all the rivets which made it pretty easy.

After lunch I puzzled out how to attach the Garmin GAP-26 plumbing to the pitot and AOA lines. I was going to just order a duplicate of the fittings Van's provides for the kit pitot tube, but I discovered they are sized for 1/4 inch tubing and the GAP-26 has 3/16 inch tubing. I started looking for the proper AN fittings in the Aircraft Spruce catalog - there a lot of choices. Then I remembered I had a lot of plumbing parts left over after installing the static ports. I had ordered the Avery EFIS System Plumbing kit from Aircraft Spruce when I was working on the tail cone. It turns out that it has fittings for the GAP-26 aluminum to plastic tubing connections.

 I pulled the pitot and AOA lines through the wing. Then I worked on installing the aileron actuator on the end of the wing. I had cleaned and primed the tubes a couple days ago. The tubes had been a close fit before painting and now they didn't fit at all. I spent a couple hours sanding primer off to get the tubes to fit together again and then applied a good coat of grease and slipped them together. When I went to fit them in the end of the wing I discovered I had to sand even more because you need to slip the inner tubing well past the mark to get the assembly to seat in the bearings.

I purchased the optional aileron trim kit OP-38 from vans. It includes hardware and a few aluminum parts and a Ray Allen trim servo. When I ordered it I didn't realize the kit also included an LED indicator and an on/off switch for the panel. I will be controlling the trim using the hat switch on the top of the control stick and the G3X display will show the trim status so the included LED indicator and on/off switch will go unused. I would have been $$ cheaper to order the trim servo without the switch and LED.

I also purchased 2 of the Aero LEDS Sunspot LX landing light kits which include the LED lights, mounting brackets and assorted hardware. Unfortunately I could not find the 2 baggies that have the hardware so I will have to contact Van's tomorrow after the holiday.

Van's recently introduced a mounting kit for the Garmin GMU-22 Magnetometer. It includes a mounting bracket that replaces the Dynon ADAHRS mount in the left wing. The wing wiring for the Dynon ADAHRS can be repurposed to attach the GMU-22 so it seems like a good deal. Some builders have reported interference from the wing tip strobes causing the GMU-22 to fail, but I'm running an extra pair of shielded wires to my strobes so hopefully that won't be an issue.

Note: The mounting ring for the GMU-22 is not included in the kit from Van's. I ordered all my avionics from SteinAir and they provided the GMU-22, but it did not include the mounting ring either. I'll have to talk to SteinAir about providing the ring.
