Tamiya 70113 4WD Learning Chassis - STEM Dual Star Kit  [70113]

About the Tamiya 70113 4 Wheel Drive Chassis Kit

The Tamiya 70113 4 Wheel Drive Chassis Kit is a practical project that introduces builders to drivetrain engineering and chassis design. As part of the STEM Series, it focuses on demonstrating mechanical concepts through assembly and testing.

Design Highlights and Frame Layout

The pre-cut wooden chassis keeps construction straightforward while offering a rigid platform for the drivetrain. The shaft-driven four-wheel configuration mirrors full-size 4WD layouts and helps the model maintain momentum over bumps and irregular surfaces.

Mechanics of the Drive and Traction

Drive is carried from a central gearbox to each wheel gearbox using a hex shaft, delivering even power to all wheels. Semi-pneumatic tyres provide added grip and the included roll bar protects the frame in case of rollover incidents during trials.

Who Benefits from This Kit

This kit is suitable for schools, clubs and individual enthusiasts interested in practical lessons on power flow, gear interaction and vehicle behaviour. Builders can alter components to test improvements or compare setups.
