FYI to builders...pondering servo size (strength) when installing their autopilot system. I have a STOL 750 with two axis autopilot ( Dynon SV-32 servos.)   During my 40 hr test phase I was having problems getting the autopilot pitch servo to not slip - esp. in turbulence.  Went thru the whole setup routine per Dynon, but no joy, airloads were too much for the servo as the A/P worked to maintain…
