I have the above joystick and have a problem on autopilot or if i try to trim out as the stick moves backwards and forwards violently uncontrolled. Can you calibrate the stick to stop this?

I have the same stick (USB interface) with no problems.I did reduce the forces to about 40% they all seemed a little too violent for me at 100% but I don't get anything out-of-the-ordinary, now.Art.
