Propellers and blades are easy to handle, and the vehicle moves by using the reaction force of air. The frame is light, allowing it to travel farther and faster. It is a teaching kit for science and technology. The working principle is: after turning on the power, the battery provides electricity to the motor, which rotates and drives the blades to rotate, blowing air backward, and the reaction force of the wind acts on the car, making it move forward. There are three interchangeable types of science and technology kits for children, which use the principles of air and rubber band power to push the car forward.

Warm Tip: Three models are interchangeable, not three models installed at one time.
