Tamiya 70103 Universal Gearbox Kit
Unlike the other gearboxes in Tamiya’s series, the universal gearbox has a thin metal frame, making it the smallest Tamiya gearbox. The final two gears are metal, making for a tough output. A worm gear allows for the high gear ratio options of 101:1, 269:1, and 719:1.

Notes:
- 1
- A theoretical speed of the gearbox output shaft can be computed by dividing this speed by the gear ratio.
- 2
- This is the no-load current of the motor when disconnected from the gears in the gearbox; the no-load current of the entire gearbox with the motor connected will be slightly higher and will vary depending on the gear ratio.
