This video is a Hobby Estore Video Tutorial that will show you how to repair or replace the ACME remote start system in your radio control cars. You will know you need to take this step when your RC car doesn't start or when you push the start button and all you hear is a clicking noise. The first step is to remove the remote start system and this can be accomplished by taking the top cover off of the car and then unhooking the exhaust hose from the remote start system. Then take the cover off of the system and visually inspect each gear, you will be able to see if there is a tooth missing from a gear. If there is, it is a simple fix to replace the gear. If you notice that no gears are missing teeth then you will want to replace the whole system.
