Thanks Brian. I think I prematurely jumped to the AP functioning and trim with the G3X. Since I have the professionally assembled harnesses I do have wires to hook up a trim position sensor installed. I even have the trim LED bar from Ray Allen but I would need a sensor. I don't aim to install it. Trim is felt in your hand with the exception of setting trim for departure. I can count to three or whatever it takes to set the trim just as I did during the transition training at Stick and Rudder. While speaking of the Safety Trim, be sure you are getting the "Safety Trim Booster". I got mine from Kitfox. I have looked at the TCW website after the fact and note that the Safety Trim "Booster" is not listed on their site. They do have a Safety Trim. I have no idea what the difference is but I have had John McBean specifically ask if I had the "Booster" back when I was having auto pilot servo trouble.
