Tamiya 70093 3-Speed Crank-Axle Gearbox Kit


Vendor's Description: 

Tamiya’s 3-speed crank-axle gearbox looks very much like half of the twin-motor gearbox (with an added gear ratio option). This compact gearbox can be built in one of three gear ratios (17:1, 58:1, and 204:1), and is Tamiya’s cheapest, general-purpose gearbox.
