I've installed a Tru Track Pitch servo in a 360 airframe (see picture) The
servo pushrod is connected with a clamp to the elevator control tube.
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
