Abstract
A radio control driving circuit device used for a model device having a radio control system comprising a d-c power supply, two electric motors and a receiver, characterized in that two transistors of the same type, instead of the conventional complementary type, are used as two transistors each connected in series to the right and left motors for separately driving each of the motors, and a common power supply is used for driving the motors to permit control signals from the receiver to be introduced via a phase division circuit.
