The chassis adopted FM-A with front motor layout incorporating aero design. Since the center of gravity is closer to the front of the car body, it is possible to run with a sense of stability even on courses with many ups and downs. The four rollers are also made of low friction resin, including a skid bar made of low friction resin at the bottom of the front as standard equipment. In particular, the rear roller is an 8mm thick type with improved stability. In addition, the motor can be easily replaced from the bottom of the chassis, and setting changes can be made quickly. Various parts can be attached to the aero side stay, which is inspired by the cross-sectional shape of the wing of an airplane. The chassis body made of polycarbonate ABS resin is black, and the A parts made of low friction resin are fluorescent green. The gear ratio is set to 4.2: 1.
