Okey im not so good at repairing Rc Cars but irepaired it now nad now after two days i got this problem. If i throttle it just sounds but the car is not moving???
Ive looked on it and i screwed a thing up and looked on it and putted it back. If someone wants me to put a video up i could do it anytime

Thanks!
Model: Hsp Monster 1:10 Nitro
Its about 2 years old and ive drived it 3-4 times i think and it was the first time i drove it ..
I had this problem before but my friends friend fixed it .
