All,
I recently solved a problem with my auto pilot that may be of use to some. The problem I had was at random intervals (5-20 min) I would get a "pitch servo lost" error which would usually clear after a about 30 seconds. I could re-engage the AP only to wait for it to happen again. As you can see from the pic the pitch servo is located very close to the transponder antenna, moving the antenna solved the problem. The antenna is now on the plate just behind the header tank and I have not "lost" the pitch servo since
Hope this is helpful to someone.
