The landlord did not specify the lift type of the wireless remote control aircraft: fixed wing or helicopter? \x0d\ If the lifting mode is not considered, only the remote control principle is discussed. The basic principle is as follows: \x0d\ Generally speaking, wireless remote control includes three parts: remote control transmitter, remote control receiver and actuator. The working principle of wireless remote control is that the transmitting unit transmits the control signal of the push rod by radio at a certain frequency through modulation circuit, coding circuit and wireless transmitting circuit. After receiving the signal sent by the transmitting unit, the receiving unit analyzes and processes the push rod control signal of the corresponding frequency through the demodulation circuit and the decoding circuit, and then distributes it to the corresponding actuator execution circuit to control the actuator action. \x0d\ Take the fixed-wing aircraft as an example, a fixed-wing remote-controlled aircraft needs to control six actions to ensure the normal flight of the aircraft: engine speed control, left wing flap up and down, right wing flap up and down, left tail elevator up and down, right tail elevator up and down, vertical tail rudder left and right actions, etc. This requires that the transmitting unit has six control pushrods, the transmitting unit also needs six signal channels, and the receiving unit also needs six signal receiving channels and six steering engines to complete these six actions.
