before we start I would just like to let you know im a noob so i dont know alot about RC's. Okay so i use EZ start on my car's motor and a glow starter on the RC's TRX 2.5 engine. It starts and everything seems okay but then it starts to jerk back and forth by itself and when I take the glow starter out it turns off. Am i supposed to keep the glow starter on top of it? And why is it jerking back and forth? Is it because of low batteries?

I also can't accelerate or go back with the rc even though i see a response in the steel rod going forward and backwards when i use the RC. What should I do?
