The Tamiya #70097 twin-motor gearbox is a small plastic gearbox. It contains two small DC motors that drive separate 3mm hexagonal output shafts. There are two ways to put the kit together: with a high-speed 58:1 gear ratio or with a slower 203:1 gear ratio. Either way, the motors provide plenty of power to drive any small robot.
The two low-voltage motors in the twin-motor gearbox run on 1.5 to 3.0 volts. The 3mm, hexagonal output shaft is compatible with any of the Tamiya wheels to meet different ground surface. The motor is FA-130 (18100), please refer to the datasheet for the motor specifications.
