Chassis material: all carbon fiber. Second floor board: all carbon fiber. Car shell: Red. Driving mode: four hub motor direct drive. Power source: lithium battery. Car computer: Arduino Nano. Wheelbase: 257mm. Wheelbase: 185mm. Conception Introduction: Influenced by the development concepts of future vehicles such as new energy vehicles and Internet vehicles, this remote control model is conceived. The frame specifications are designed in accordance with a 1/10 ratio, using conventional suspension and shock absorber layout, battery center, four-wheel independent drive, independent steering, and a brushless outer rotor motor of a quadrotor. The four tires are equipped with this motor, and its power, braking force, steering angle, steering left and right differential speed can be controlled separately. The algorithm can be used to achieve more flexible and diverse operating modes, and achieve richer driving/cruising pleasure for people to the car!
