This is a newly designed 4-wheeled car chassis. Unlike the regular 4-wheel drive, this car uses rear-wheel drive plus front-wheel steering to achieve forward, reverse and left-to-right turn.
In the same way as a professional remote-controlled racing car, two steering rods are used to control the direction of the trolley through the steering gear, which is fundamentally different from the acrylic overhead steering provided by other friends.
In addition, the steering mechanism of the rear wheel has also been changed. The aluminum fittings are integrally formed by pressing, and the motor and the drive shaft are tightly engaged together. The motor uses an all-metal geared motor. If you pursue high speed, you can even use a high-speed motor. As long as it is a 25 mm shaft diameter motor. The addition of two flange cup bearings to the rear wheel ensures a more flexible motor rotation.
