I have a stage 1 motor in my car. Today when i finished putting my suspension and steering upgrade(the springs are a real task to get on the dampers btw) in and went to test it, the car was driving fine and all of a sudden it made a popping noise and stopped. I noticed that the motor stopped touching the bezel. So i ripped it apart and put it back together and it ran fine until the batteries died a few minutes later. Has this happened to anyone else??
