Tamiya 69911 Single Gearbox 4-Speed Clear Workshop Gear Unit  [69911]

About the Tamiya 69911 Single Gearbox

The Tamiya 69911 Single Gearbox is designed for educational use and hobby workshops, with a clear case that exposes the gear set for observation. It helps modelmakers and students see cause and effect in mechanical systems.

Design, materials and ratios

The gearbox uses a durable ABS resin case to protect the internals while remaining transparent for inspection. It includes four gear ratios: 12.7:1, 38.2:1, 114.7:1, and 344.2:1, allowing builders to try different speed and torque combinations in their projects.

What is included and what fits

Supplied with a Type 130 motor and both left and right 3mm hex output shafts, the Tamiya 69911 links into many Tamiya constructions and can be adapted into custom assemblies for vehicles and mechanical demonstrations.
