Hi, I bought a 1 speed beginner nitro buggy from raidentech, and it worked fine until now. The controls in the car works fine, but as soon as i turn the engine on, the controls start to move by them self. So, i see that the servos move forward and backwards as soon as the engine is turned on. I changed the batteries, the crystal is in properly, and all the electronics seems to be wired together. If the engine is off, every thing seems to work normally. HELP!!!
