Visible 3-Speed Crank Axle Gearbox from Tamiya 69909

Perfect for tinkerers and educators, the Tamiya 69909 3-Speed Crank Axle Gearbox lets you test three gearing options to evaluate performance trade-offs. It suits model experiments, small vehicle drivetrains and robotics projects.

Construction and Connectivity

The transparent ABS shell provides a clear view of gear engagement and shaft action for troubleshooting and teaching. The gearbox includes left and right 3mm hex outputs to adapt to many Tamiya components and custom couplings.

Drive Components and Applications

With a Type 130 motor fitted, the gearbox supplies a reliable power source for STEM builds and creative mechanisms. Crank arms can be added to generate linear motion or drive cams and levers in mechanical demonstrations.

How do I choose a gear setting for a model car?

Choose the higher-speed setting for light-load, fast-running models and the lower-speed, high-torque setting for heavier loads or slow crawling behaviour.

Are spare parts available for wear items?

Many common wear parts such as gears and hex shafts can be serviced or replaced; consult official parts lists for matching components.

Can I run this gearbox continuously?

Short to moderate runs are fine, but for extended continuous duty check motor temperature and allow cooling intervals to avoid overheating the Type 130 motor.
