Tamiya 72005 6-Speed Gear Box for Hobby Mechanics

The Tamiya 72005 6-Speed Gear Box is a practical unit for model builders and students wanting to explore gearing in small mechanisms. With selectable ratios, it lets you experiment with different speed and torque combinations across Tamiya construction and robotics sets. Its compact assembly fits a variety of compact layouts.

Design Notes and Gear Options

The gearbox provides six gear ratios: 11.6:1, 29.8:1, 76.5:1, 196.7:1, 505.9:1, and 1300.9:1, enabling clear demonstrations of mechanical advantage. Several crank arms and an RE-260 motor are supplied to support typical classroom and workshop experiments.

Compatibility and Practical Tips

Compatible with a wide selection of Tamiya kits, this gear box is handy for builders trialling different drivetrains or creating small-scale mechanisms. It is useful for learning about gear trains and for refining prototype motion solutions.

Will the gearbox handle continuous running?

The gearbox is intended for light duty hobby and classroom use; monitor heat and wear during prolonged runs and avoid heavy continuous loads beyond typical model use.

What assembly skills are needed?

Basic model-building skills are enough; careful alignment and correct fastening are more important than advanced techniques to ensure smooth gear engagement.

Can I swap the motor for a different size?

The kit includes an RE-260 motor matched to the gearbox. You can use other motors if mounting and shaft compatibility are addressed, but check speed and torque ratings first.
