RTFM, it is explained in the second part of the engine section of the manual.
what if he bought the car on ebay and never got a manual. i never had a manual, so should i have RTFM?
on a slightly different matter, but related, when i go onto other forums like rctech.net, it blows me away cos im so used to this forum. the ppl there talk purely about rc cars, and dont post smart ar$€ replies which are attempting to bash the person who asked a simple question.
