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.

General specifications

Typical operating voltage:	3 V
Gear ratio options:	101, 269, 719 :1
No-load motor shaft speed @ 3V:	12300 rpm¹
No-load current @ 3V:	150 mA²
Stall current @ 3V:	2100 mA
Motor shaft stall torque @ 3V:	0.5 oz·in

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.
