70190 Mini Motor Multi-Ratio Gearbox (12-Speed) Kit
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, or 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).
Parts included with the Tamiya 70190 mini motor multi-ratio gearbox (12-speed) kit with quarter for size reference.
The kit includes step-by-step illustrated instructions in both Japanese and English. A scanned copy of the instructions is available on the Pictures tab. The kit can be built with just a screwdriver, but the instructions recommend having side cutters, tweezers, and a modeling knife on hand. The gearbox kit’s motor has a 030 form factor that is smaller than the Tamiya gearboxes that use the Mabuchi FA-130 motor.
