A kit is vehicle which needs to be assembled. Kits include most of the neccessary pieces to build a working RC, aside from the electronics. Electric kits usually require a speed control, motor, radio system, servo(s), battery and a charger. Nitro kits will usually require fuel, a radio system, servo(s) and a glow-starter. Some nitro kits do not come with an engine. All kits require special tools such as hex drivers, phillips screwdriver, hobby knife, needle-nose pliers, curved scissors and a Dremel or other cutting tool. Paint must be purchased seperately according to the customers preference.
