dont buy this crap it sets on fire burns out your truck and you get no help. only told to send the esc and motor back. and jumped to conclusions about my batteries before they even know what batteries im using. they say use over 4000 mah and 30c. mine are 6000mah and 100c. laughing about this and never buying rc rubbish again. goin back to real sized motorcycling it was cheaper and less fires! it was fun while it lasted though but after spending over 900 quid it was just a massive waste. castle suck.
