Hey,
I have an issue with a servo. It is the standard throttle servo. It was the traxxas one that came with my car. I have had the car for about a week. I was driving when suddenly the car took off and It would slow down or brake. I got it and the throttle servo wouldn't move. I took It apart to see the problem but it looked normal so I think one of the gears keeps falling out of place. Then It did it again. I smacked the servo then It worked again.

. Does anyone know a way to maybe stop this from happening.
Thanks,
Jeff
