The problem I had/have is that I am using the retract channel to control gain (two position switch) and without reversing the servo (or changing the mounting and linkage) the gain would only go the the side with AVCS (HH) with the gear in the down position.

I have no problems with the way my airplane is set up and flying now so I don't really want to mess with it, but I do realize now that there are some other options for setting this gyro that might be a little easier.
