As the elevator push tube can twist left and right with its eyeball bearings, there is quite a lot of play in the system. The play at the stick is ca 1/2 inch. (Have not been flying with this installation yet) Are there any better solutions out there?? I don't think you will be happy with this installation for the reasons you note above. I attached the end of the autopilot pushrods to a bellcrank for both pitch and roll. This effectively accepts only linear motion. Works well on my IV-P Bob
