2. Description of the Related Art Various radio control models of airplanes, helicopters, cars, boats, and the like have been known. When flying or running these radio-controlled models, the pilot operates the operation stick of the transmitter to transmit a signal modulated with operation data corresponding to the operation amount. On the other hand, the receiver mounted on the radio control model receives a signal from the transmitter and demodulates operation data from the received signal. The demodulated operation data is supplied to an actuator for controlling each part of the radio control model. Thus, the radio-controlled model performs a so-called proportional operation in proportion to the operation amount of the operation stick of the transmitter.

In addition to performing the scan of the frequency band assigned in the above, the transmission channel monitoring circuit 13 determines an empty channel. Then, the transmission / reception frequency of the wireless unit 12 is selected from the empty channels determined by the transmission path monitoring circuit 13.

Next, the control radio 1 enters the transmission mode, in which the transmitter 12a of the radio unit 12 transmits a connection signal () to the model radio 3 at the selected predetermined channel frequency, and after the transmission, Is switched to the reception mode, and is in a standby state for receiving the recognition signal returned from the model radio 3.

At the same time, after the transmission of the model operation signal, the mode is switched to the reception mode of the model information signal to be in a standby state for receiving the model information signal from the model radio 3. Then, after receiving the model information signal, the mode is switched to the transmission mode again and the model operation signal is transmitted, so that the operation of transmitting the model operation signal and the mode of receiving the model operation information are alternately repeated.
