My Trutrak autopilot roll servo has gone into the stick shaker mode, I didn’t know this was an option.

Anyone have any ideas on what would cause this?

One of two things

Thanks for the video, always helps with diagnosis!

It is one of two things...
1. A broken wire at pins 2,3,4, or 5 at the servo (or the corresponding pins at the controller)
2. The servo amp has failed. If this is the case, you have two choices - overhaul or replace. If you are in the US, give Mid Continent a call and get the quote for both...I suspect a new one may actually be more affordable.
