The Tamiya 72003 High Efficiency High Power Gear Box HE is built to give extra mechanical advantage where projects demand more torque. It is a robust choice for hobbyists building motorised models and experimental rigs.
Powered by a RE-260 motor, this gearbox offers two gear ratios, 41.7:1 and 64.8:1, so you can configure the output for higher torque or increased speed. Multiple crank arm styles are supplied to broaden the range of possible linkages and motion outputs for custom assemblies.
Its flexible design makes the gearbox suitable for educational setups, kit upgrades, and bespoke hobby projects. It pairs well with other Tamiya parts to expand functionality and simplify integration into existing builds.
