Factory Direct Sale Remote Control Helicopter Aircraft Toy with Altitude Hold, One Key Takeoff/Landing

The takeoff, flight, landing, and other actions of remote-controlled helicopters are mainly completed by each rotor. When the main rotor blades rotate, they generate an upward airflow relative to the air, naturally forming a lift force. By utilizing the rotational speed of the rotor and the angle changes of each blade, the aircraft can perform various flight actions such as takeoff, elevation, and landing.

A toy helicopter is a flying toy that can be controlled from a long distance, usually consisting of one or more rotors and engines. These toy planes receive signals through the signal receiver of remote control devices, and then generate lift through the rotation of the rotor, causing the aircraft to take off and fly.
