This is a developed 4-wheel vehicle chassis, and regular 4-wheel drive is not the same as this car, which has a rear-wheel drive and front steering to move the car forward, backward, and turn left and right.

The use of two rods through the steering servo to control the direction of the car is also a professional remote control racing method. In addition, the rear-wheel steering system has been modified. The motor is integrally formed with the aluminum mounting piece, and the motor is securely connected with the driving shaft. The gear motor is made entirely of metal. If you want to go fast, choose a motor with a 25mm shaft diameter.
