This gearbox has four possible gear ratios, including the highest gear ratio of Tamiya's gearbox series, 5402:1. The other options are 126:1, 441:1, and 1543:1. This gearbox also features a worm gear, which locks the output shaft when the motor is not turning. A clutch gear prevents the gearbox from destroying itself in case the output shaft gets stuck.
The motor is rated for 3 volts but will typically work fine up to 6 volts. When using this product with the dual serial motor controller (or any motor driver based on an H-bridge), keep in mind that up to a few volts (depending on the load) are lost on the transistors of the H-bridge, so that a 4.5 volt battery delivers about 3 volts to the motors, giving them a reasonable amount of power. Motor overheating can be caused by excessive stalling, even at very low voltages. We recommend that you use stall-detection sensors, or just watch your robot, to make sure that it doesn't stall for more than a few seconds at a time.
The 3mm, hexagonal output shaft is compatible with all four types of Tamiya wheels.
(Note: This gearbox uses the 18100 motor variant)
