| The electronics is a single board (WB-1407R) containing an RX-2B remote control receiver chip, aerial circuitry, and a bridge of eight transistors (4x HY33 A1300, 4x AE9T) to drive the motors. There is also a fuse on the power line. | The electronics is a single board (WB-1407R) containing an RX-2B remote control receiver chip, aerial circuitry, and a bridge of eight transistors (4x HY33 A1300, 4x AE9T) to drive the motors.

| All the electronics are on one small board which has the switches mounted directly on it. There is one 27.145MHz crystal, one power-on LED, and a TX-2B remote controller transmitter IC. | All the electronics are on one small board which has the switches mounted directly on it.
