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)

Hello, I am currently looking at purchasing this gearbox (Tamiya 4 Speed Crank Axle Gearbox Item #70110). But I noticed that there is no mention of what the output torque of this gearbox is. The specifications that I am currently looking for is a torque value of 2-4Nm with a motor (60-180rpm) given a power of 75W. Will this gearbox be able to provide a torque of 2-4Nm under these conditions? Thank you!

I am looking for a substitute for the Tamiya 6 speed motor gearbox, which you say is unavailable at the moment. A gear ratio of 1:1543 will suit my application, but can you confirm that the direction of the final drive can be reversed by changing the voltage polarity applied to the motor?

I'm building a small (~ 30cm x 30cm ) battlebot. The combats will be based on pushing the opponent out of the ring thus i guess it will be stalled against the opponent a lot of the time. Should I use this gearbox as it has a cluth gear? or is the Tamiya 70167 (http://www.technobotsonline.com/tamiya-70167-single-gearbox-4-speed.html) more suited to this kind of robot? PS. I will need two of them one for each wheel, I0 thinking of going for 2 singles instead of a double because the doubles are too narrow for the job.
