A radio-controlled device is provided that has improved steering responsivity. The radio-controlled device consists of a transmitter, a receiver, and digital servomechanisms. A PPM signal format of signals transmitted from the transmitter is shown in FIG. 4 (a). Signals having time widths (T 1 , T 2 , t 3 ) proportional to displacements of a transmitter joystick are distributed to drive the servomechanisms. As shown in FIG. 4 (b), the transmission side transmits, to a final channel CH 3 , a signal having a time width of T 3 (=t 3 +R), being the sum of the time width t 3 and a reset reference value R (Nt 3 -Nt 1 ). The receiver side subtracts the reset reference value R, thus restoring it to the original time width t 3 . By adding the reset reference value R, the minimum value L 3 of a signal in the final channel is larger than the maximum value V 1 of other signal.
