Description:

This 4-Speed Crank Axle Gear Box is small but has a lot of power. There are four gear ratios to choose from, including the slowest ratio that allows for two rotations per minute. Two crank arms are included for added flexibility in the design of projects. A FA-130 motor and wiring cord are included.  Use this gear box and motor set with other Tamiya Construction and Robotics products.  Add your own wheels, hubs or tracks.  This gear motor requires assembly.
