The Tamiya 70110 4-speed crank-axle gearbox has four possible gear ratios, including the highest gear ratio of Tamiya’s gearbox series, 5402:1, as well as 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 kit comes with all parts necessary to build the gearbox in any of the four possible configurations.

Typical operating voltage:  3 V 
Gear ratio options:  126:1, 441:1, 1543:1, and 5402:1, 
Free-run motor shaft speed @ 3V:  12300 rpm1 
Free-run current @ 3V:  150 mA2 
Stall current @ 3V:  2100 mA 
Motor shaft stall torque @ 3V:  0.5 oz·in3 
Color:  grey 

The low-voltage motors run on 3-6 volts and draw up to a few amps, making them perfect candidates for the Pololu Orangutan LV-168 robot controller Product Code 775, which incorporates these low-voltage motor drivers.
