Tamiya 72005 6-Speed Gearbox Educational Kit  [72005]

Tamiya 72005 6-Speed Gear Box for Prototyping

The Tamiya 72005 6-Speed Gear Box is aimed at enthusiasts and students building small mechanical projects and robots. It supplies a selection of ratios so builders can tune outputs for different loads and behaviours. The compact construction helps integrate the unit into tight model spaces.

Gear Selection and Performance

This gear box offers six ratios: 11.6:1, 29.8:1, 76.5:1, 196.7:1, 505.9:1, and 1300.9:1, covering a broad performance range. The set includes crank arms and an RE-260 motor to illustrate practical gearing effects in tests and demonstrations.

Applications and Setup Advice

Designed to work with many Tamiya kits, the gearbox is useful for educational tasks and hobby prototypes that need variable gearing. For best results, match gear choice to the motor and intended load, and check alignment during assembly.
