The SU-01 chassis features a TRE - 01 unit that integrates an ESC (Speed ??Controller) and a receiver at the center of a light and strong enough monocoque frame, a battery case under it A rear wheel drive type with excellent weight balance. Suspension is a simple strut type four wheel independent. We installed a motor on the rear end to make the rear wheel of the drive wheel sufficiently tractioned, and also equipped with a differential gear that creates smooth cornering in the sealed gearbox. In addition, the 370 motor also points the length of running time. Furthermore, you can switch the speed of two stages of normal power by providing a speed change switch on the back of the transmitter.
