Sorry for the late reply, I have been away on vacation. Mine has a very simple setup, no expo on the controls and a belcrank on the throttle to use alot of servo throw with very little throttle plate movement if that makes sense. I did add a little more up elevator as the cg moved forward after replacing the OS 120 with a G23. It allowed much better 3 point landings. Attached is a picture taken at the State of Maine Scale Shootout last weekend parked next to Charlie Nelsons Waco. The crowd seemed to like Barbi riding the top wing and the old G23 belching smoke. JC
