Abstract
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.(). Signals having time widths (T, T, t) proportional to displacements of a transmitter joystick are distributed to drive the servomechanisms. As shown in FIG.(), the transmission side transmits, to a final channel CH, a signal having a time width of T(=t+R), being the sum of the time width tand a reset reference value R (Nt−Nt). The receiver side subtracts the reset reference value R, thus restoring it to the original time width t. By adding the reset reference value R, the minimum value Lof a signal in the final channel is larger than the maximum value Vof other signal.
