This precision 6-Speed Gear Box, High Efficiency, is a compact unit with a variety of gear ratio options to choose from. Several crank arms and a RE-260 motor are included. This versatile, high-efficiency gearbox lets you build one of six different gear ratios so you can select the best combination of speed and torque. Whatever your application, chances are that one of the configurations will do the job. A clutch gear protects the gearbox in high-gear-ratio configurations so that the gearbox doesn't rip itself apart if the output shaft gets stuck.
The 5mm, round output shaft is compatible with the Narrow tire set. Perfect for many Tamiya Construction and Robotics projects. Some assembly required.
Gear Ratios: 11.6:1, 29.8:1, 76.5:1, 196.7:1, 505.9:1, and 1300.9:1
