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 and our 4 mm universal mounting hub. Our 3 mm universal mounting hub also fits on the smaller threaded end of the shaft, although it is not specifically intended to work with this type of shaft (the hub’s set screw could damage the thread on the shaft).
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 our DRV8833 motor driver carrier if appropriate precautions are taken to avoid stalling the motor.
- One type 260 motor. For motor specs, see the Mabuchi motor RE-260 (#2295) data sheet (59k pdf).
- Four different gear ratios:
- 4 mm round output shaft (length: 100 mm) compatible with Tamiya wheels for 4 mm, round shafts and our 4 mm universal mounting hub.
