Shy,
At the risk of telling you how to suck eggs -
Setpoint = TR pedal control
Load = TR Pitch change or duplex bearing
Feedback lever disconnected at the hydraulic cylinder (servo)
Disconnect the feedback lever after the hydraulic valve has moved and there is nothing for the input side to work against to shift it again. Moving the pedals would more than likely just move the free end of the feedback lever not the pilot valve.
