Default Servo movement after the fact

Hi guys,,

I have some servos that when radio stick movement is activated to the farthest point suddenly...
the servos move to the end point and stop and then a 1/2 second later moves a
tiny bit more in the same direction. I have tried changing the end point . That did not help.
They are on 6 volt and have proper voltage. They are metal gear and digital . my
receiver is analog futaba . I had this same problem with a digital receiver..
Lets not just say they are cheap servos what causes this.
How can I fix this
Thanks
David

David, plug your battery and servo directly into the receiver and see what happens. Dan.

Wires, connectors, servo reverses, power distributors, anything can be the source of a failure. The easiest way to find out the cause of the failure is to isolate it. Maybe it's the receiver. Start removing, exchanging, replacing, you name it any thing that is in series from your transmitter joy stick to the control horn to find the problem. It may be the transmitter or even your new servo reverser. Post your results. It's somewhere. We can all benefit from it. Dan.

Servo reverser devices can be problematical new or not. Remove the device and test without reversing the servo to confirm it is not the reverser.

A club mate was having a jittery throttle servo. LONG story short, it was the TX (throttle stick) that was the problem.
