ABSTRACT OF THE DISCLOSURE Disclosed is a radio-controlled toy comprising a transmitter designed to transmit a signal amplified and modulated with a low-frequency square signal by the supply of power effected by closing a switch and a receiver having a receiving circuit portion and a forward-to-reverse switching control. The transmitter may be comprised of an astable multivibrator for producing a low- frequency square signal and a crystal oscillation circuit. The forward-to-reverse switching control is designed such that when no signal is received, a d.c. motor turns forward and when a signal is received, the d.c. motor turns in reverse.
