After reading a few forum posts regarding using the RV-14 yaw servo mount on the RV-10, I decided I was up for it. It is a significant savings over the Garmin part. I probably spent more time researching and planning than actually doing. Some people opt to bolt the bracket in place so that it is removable and easier to access the back of the tail in the future. I opted to just rivet it in and probably regret it later. Not a lot of pics because it was very hard and much of the work was blind. I did get the bracket cleco'd to the upper plate and confirmed that the center hole of the bracket, which is meant to clear the head of the bulkhead rivet on an RV-14, does not clear the rivet on an RV-10. Glad I didn't rivet any of that bulkhead yet. I managed to dimple the bulkhead and squeezed a flush rivet. I then squeezed the upper bulkhead to bellcrank assembly rivet but I had to buck the bottom ones. Not too bad, just very awkward. Then temporarily installed the yaw servo bracket assembly so that I could blindly drill the holes from the back side, through the bulkhead. I had already confirm by sticking a red sharpie through the holes that they would be roughly in line with the existing holes and maintain minimum spacing. What a pain, but eventually got it. Then disassemble, deburr, countersink the holes in the top plate and then quick prime. Opted to just do self-etch in the rattle can. Will try to assemble tomorrow.
