Mini Motor Gearbox - Multi 12-Speed

The mini-motor gearbox kit from Tamiya makes it easy to get a small robot or plastic model moving.

The kit includes one brushed DC motor and all the gears and parts to build any of the twelve possible gear ratio configurations:

4.6:1,

5.1:1,

9.7:1,

10.8:1,

20.4:1,

22.6:1,

42.8:1,

47.5:1,

89.9:1,

99.8:1,

188.7:1,

209.7:1.

The twelve gear ratio options give you the flexibility to choose the best speed and torque for your project. There are two possible output axle locations (only one output location is possible for any given ratio).
