The invention discloses a model
airplane remote control system, belonging to the field of
remote control equipment. The model
airplane remote control system mainly comprises a
crystal oscillator, a high-frequency circuit, a transmitting antenna, a power supply, a control lever, a variable
potentiometer, an
encoder, a switch circuit, a
frequency selection circuit, a receiving antenna, a steering engine, a decoding circuit, and an amplifying circuit, and is characterized in that the control lever is connected with the variable
potentiometer, the variable
potentiometer is connected with a signalgenerator and the
encoder, a
signal generated by the
encoder passes the switch circuit and then is carried on the high-frequency circuit, the
crystal oscillator generates oscillation frequency, and finally, the transmitting antenna sends out the
signal. The receiving antenna is connected with the
frequency selection circuit, the
frequency selection circuit is connected with the
crystal oscillatorand the amplifying circuit, the frequency selection circuit selects and transmits a matched
signal to the amplifying circuit, the amplifying circuit is connected with the decoding circuit, the signalis amplified and then is converted by the decoding circuit, and the decoding circuit is connected with the steering engine.
