Yeah we are getting a weed trimmer engine from a friend and were wondering if there was some sites about how to go about puting them in an rc truck/car?? Any help at all would be greatly appreciated!!! Thanks!!

I'm looking to buy a rc truck or car. Preferably a truck. Does anyone know of a battery powered one that will go VERY FAST? A battery powered RC truck. Not looking to spend anymore than $100, because that's just crazy. It needs to be tough too. Just tell me the brand and name and what not so i can find it at a local store.
PS How do you tell how fast it is by reading the description?
