Tamiya 70168 Double Gear Box - Suited to Education and Prototyping

The Tamiya 70168 Double Gear Box lets builders learn mechanical concepts by building and testing. With four selectable gear ratios it supports experiments that compare speed against torque, making it useful for prototypes and teaching labs.

Independent Sides for Experimental Builds

Each side of this double gearbox can be set to a different ratio, so you can compare behaviours side by side or create asymmetrical drive setups. This is useful for students and hobbyists exploring drivetrain concepts.

Durable Components and Included Motor

Manufactured from durable plastic components, the Tamiya 70168 is designed for repeated assembly sessions. The kit includes an FA-130 type motor, a motor cover and a crank arm for immediate use in models.
