I installed my aileron trim system in my -14 wing yesterday. It uses the same trim kit as the -10, and I'm wondering if anyone has had problems with this setup now that there are quite a few hours on the collective RV-10 fleet. Specifically:
1) When I move the pushrod back and forth I can see the inspection plate and surrounding skin deform under the load where the trim servo is mounted. With enough cycles it looks to me like it's inviting cracks to form in the skin around the inspection opening and/or along the rivets that hold the skin to the ribs on each side of the inspection plate. Anyone seen issues in this area?
2) The springs contact the pushrod adjacent to the attachment brackets. This seems unavoidable because the brackets don't provide enough stand-off from the tube to allow the springs to attach without contacting the tube itself.
Seems like a steel spring chafing against an aluminum tube is eventually going to wear into the tube. It is also going to be difficult to inspect. I'm thinking about wrapping a piece of UHMW tape or something similar around the tube where the springs make contact to provide some protection there. Has anyone else tried this?
Thanks,
