Tamiya 70113 Dual Star Wooden 4WD Chassis Kit  [70113]

Tamiya 70113 Kit - Practical 4WD Chassis Project

The Tamiya 70113 4 Wheel Drive Chassis Kit provides a clear, hands-on way to study mechanics and vehicle systems. This STEM Series model suits hobbyists and students who want to see how a four-wheel shaft-drive setup distributes power across a chassis.

Chassis Build and Structural Details

The kit's pre-cut wooden chassis reduces cutting and shaping work while keeping the frame sturdy. The unit uses a shaft-drive arrangement that mimics larger vehicle drivetrains, giving real demonstrations of torque distribution and balance on uneven tracks.

Transmission and Handling Characteristics

Power flows from the central gearbox to the wheel gearboxes via a hex shaft, ensuring balanced 4WD drive. Semi-pneumatic tyres enhance traction on mixed surfaces, and the included roll bar offers extra protection if the model flips during testing.

Educational Uses and Project Ideas

This model is well suited to classroom projects, science fairs and solo build sessions where learners can test gear changes, observe handling differences and experiment with basic vehicle dynamics.
