Abstract
A wireless trans-ceiver control system for a motor driven toy vehicle having a transmitter for generating a predetermined carrier of selected high frequency, and a receiving unit including a super regenerative detection circuit for receiving the high frequency carrier and normally producing an amplifiable noise signal which is attenuated by the high frequency carrier. A relay switch, for reversing the power to the electrical motor driving the toy vehicle, is energized by the amplified noise signal to retain the switch in one position and release the relay to a second position when the high frequency carrier from the transmitter attenuates said noise signal. In a modification, a gearing train drives the vehicle in one direction in one position of the switch but drives the vehicle in the same direction and also turns the wheels for turning the vehicle in the second position of the switch.
