Hi, I have a twin elevator set up with 2 S9202s on either side. Whenever I move the elevator stick the left elevator moves and holds properly but the right one moves and then retracts a couple of millimeters. the blip is most visible at the extreme ends, both up and down but it also happens for small moves on the sticks. What can the problem be and how do I fix it please?

Regards,

The first thing to try is swapping the connectors. Sometimes, what you are seeing is the result of a dirty connector. A long "Y" harness or servo extension can also cause the problem. If you can connect the servos directly into the receiver, try that and see if you still have the one servo 'bounce'. If you do, then the servo most likely has a bad potentiometer. Otherwise, you may need to replace your "Y" harness or extension.
