Radio controlled model vehicle - has electric drive and remote control system with loudspeaker on chassis for relaying recorded or direct sound transmitted from panel

摘要

The radio controlled model vehicle is electrically driven and operated by a remote control transmitter of the standard type apart from a microphone which is mounted on the control box itself. This microphone is used to transmit modulated sound to the vehicle, where it is demodulated and emitted by a loudspeaker (26) mounted on the vehicle chassis (20). The chassis (20), also holds the drive motor (22) the battery clamp (21), the servo mechanism (24), the receiving antenna (25) and the receiver (23). A tape recorder can also be connected to the transmitter, allowing any desired sound to be emitted from the vehicle e.g. music, speech, instructions etc. An inertia switch (27) can also be mounted on the vehicle chassis (20), allowing tyre squeal to be simulated when the vehicle brakes harshly or turns sharply. The vehicle itself is controlled in the usual way by levers mounted on the control transmitter unit.
