Abstract:
1. A radio-controlled device, comprising: a transmitter for serially arranging control signals in plural channels and transmitting said control signals as PPM-modulated carrier waves; a receiver for receiving and decoding said carrier waves and thus restoring said carrier waves to control signals for said plural channels; and a servomechanism for converting said plural control signals into mechanical displacements, respectively; said transmitter having modulation-signal reference value addition means for adding a modulation-signal reference value to control signals of remaining channels, except a final channel arranged at the end of said plural channels, and adding a reset modulation-signal reference value to only said control signal of said final channel; and said receiver having reset reference value subtraction means for subtracting a reset reference value from said control signal of said final channel decoded.
