1. A radio control transmitter comprising:
- (a) a transmission unit configured to transmit a signal via radio communication;
(b) a reception unit configured to receive a signal via the radio communication; and
(c) a transmission and reception control unit configured to set a transmission mode period and a reception mode period in each of frame periods, wherein a frequency is switched by frequency hopping on a per-frame-period basis;
control the transmission unit to transmit a first signal to an other radio control transmitter of a communication partner in the transmission mode period; and
control the reception unit to receive a second signal transmitted by the other radio control transmitter of the communication partner in the reception mode period,wherein, when a function of an instructor'"'"'s radio control transmitter is enabled, the transmission and reception control unit is further configured to control the reception unit to receive a trainer signal as the second signal from the other radio control transmitter of the communication partner, the trainer signal containing maneuvering information corresponding to maneuvering operation directed to the other radio control transmitter of the communication partner; and
is configured to control the transmission unit to transmit a direct maneuvering signal as the first signal to a receiver of a radio-controlled object for controlling the radio-controlled object, the direct maneuvering signal containing the maneuvering information contained in the trainer signal received by the reception unit.

Abstract
A maneuvering signal for controlling a radio-controlled object is transmitted using 2.4 GHz band frequency hopping techniques. In a trainer mode, an instructor'"'"'s radio control transmitter is configured to transmit the maneuvering signal and receive a trainer signal in each of frame periods by which a frequency is switched in accordance with the frequency hopping scheme. A trainee'"'"'s radio control transmitter is configured to transmit the trainer signal for each of the frame periods by which a frequency is switched in accordance with the frequency hopping scheme.
