I have a Futaba S9650 servo on my T-Rex and it is sticking, IE it will not return to center, does this indicate that the servo is hooped or does it need some maintenance? If it does need maintenance, what needs doing?

Is your servo connected to a heading hold gyro, when a stick input was initiated (either left or right) ?

If you are on heading hold mode the servo might not return to its center position. To determine if the servo is not centering.. connect the servo to a regular receiver channel (ie Aileron or Elevator channel) move and let go your stick. The servo should be back to its centering position. If not then that servo has some issue. Hope this helps!

That's normal on a heading hold gyro. to test the servo, just switch to rate mode on your transmitter. the servo should now move equally in both directions.
