I attemptd to replace the servo stop bracket and could not find a way to get the scews out of the servo holding the old bracket. It looks like the screws have a small hex head , but could not get an allen wrench on it. I can barely get my fingers into the area. Can anyone give me some advice on how they changed the bracket. I was getting spoiled with the autopilot. Never had one that worked as well. I certainly would like to get it back in service.
