Tamiya 70228 Arm Crawler - Educational RC Model

The Tamiya 70228 Arm Crawler is a hands-on model that teaches the basics of remote control systems and mechanical assembly. Its kit format encourages learning by doing, suitable for individual study or small group projects.

Track System and Load Climbing

The design uses four rotating tracks, with two mounted on independent arms, enabling the model to surmount obstacles up to 45mm. The arm rotation shows how changing contact angles affects traction and stability.

Assembly Insights and Exposed Gearbox

Assembly covers both the chassis and the included 2-channel remote, giving builders insight into components and wiring. The clear gearbox panel makes gear interaction visible, which is useful for understanding speed and torque trade-offs.

Ideal for Starters and Model Fans

Suitable for newcomers to RC and those curious about simple circuitry, the kit features yellow body parts for an industrial look and clear identification during testing and demonstrations.
