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.
