The first in Tamiya's "high efficiency" series, the planetary gearbox features two 4:1 and two 5:1 stages that can be combined in any way you like--you can even combine two kits to get really huge gear ratios. The output is always conveniently on the same axis as the motor shaft. Available gear ratios are 4:1, 5:1, 16:1, 20:1, 25:1, 80:1, 100:1, and 400:1.

The motor is rated for 3 volts but will typically work fine up to 6 volts. When using this product with the dual serial motor controller (or any motor driver based on an H-bridge), keep in mind that up to a few volts (depending on the load) are lost on the transistors of the H-bridge, so that a 4.5 volt battery delivers about 3 volts to the motors, giving them a reasonable amount of power. Motor overheating can be caused by excessive stalling, even at very low voltages. We recommend that you use stall-detection sensors, or just watch your robot, to make sure that it doesn't stall for more than a few seconds at a time.

The 4mm, round output shaft is compatible only with Tamiya's sports tyre and narrow sets.

(Note: This gearbox uses the RC-260SA-2295 motor variant)

See 'Which Wheel' tab for suitable wheels type 4P for a tight fit.
