Hi Pete,
I want just connect an electrical motor like servo to move a beech 90 yoke following the deflection of the ailerons and elevator.
the normal working procedure in a real aircraft:
In autopilot mode, the elevator yoke deflection follow the DV or the autopilot command and the elevator trim have to move just to reduce the "force" from the elevator motor.
In flight simulator, in manual mode, everything working fine because the deflection follow the yoke, but in autopilot mode, the elevator go to 0 and don't move any more. so if I want to connect the elevator motor, nothing happened for the elevator, just 0 centering.
I'm pilot and it's very strange for my to see trim moving without elevator deflection following it...
For information, if we move the yoke during the autopilot is connected, flight simulator make the correction for all deflection follow the autopilot and not the yoke, that resulting an offset between yoke position and deflection. On real aircraft we have cable between yoke and flight control, and it's not possible to have any difference between both during the flight...
So for me, the priority have to be on yoke and not on the autopilot in any mode, but I think it's Microsoft problem, not your ;-)
Best regards
Phil
