here is a custom built r/c rail dragster car, built of fiberglass. front end is basically a pan car setup for the narrow chassis, front alloy wheels with o ring tires, transmission is a stock all metal gear Traxxas transmission, currently has a differential but I'm included a full replacement gear set so you can epoxy the extra set and install a locked rear diff which would probably give better hole shots off the start line. the traxxas transmission allows you to use any pitch gear and any ratio you decide to go with . I'm also including a brushless Hobbystar motor, its a 58kv motor so this will be able to really move even just on 2 or 3s batteries
