Tamiya 4-Speed High-Power Gearbox Kit incl. Motor

The Tamiya 72007 4-Speed High-Power Gearbox kit includes one brushed DC motor and all the gears and parts to build any of the four possible gear ratio configurations: 39.6:1, 47.6:1, 61.7:1, 74:1. The four gear ratio options give you the flexibility to choose the best speed and torque for your project.

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, pliers, and a modeling knife on hand.

This gearbox has a 4 mm diameter, round output shaft, which works with the wheels that are compatible with Tamiya 4 mm, round shafts.

The low-voltage motor in this gearbox runs on 1.5-4.5 volts and draws up to a few amps when stalled, making it compatible with f.ex a DRV8833 motor driver carrier if appropriate precautions are taken to avoid stalling the motor.
