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 remote-controlled aircraft refers to an aircraft that can control flight from a long distance. Most remote-controlled aircraft are sold as all-in-one machines, and the manufacturers have already debugged them. For some beginner models, they have reached the state of ready to fly, and the prices are relatively low.
