Tamiya 70225 Shaft Drive Unit - Educational Mechanical Kit Module  [70225]

Introduction to the Tamiya 70225 Shaft Drive Unit

The Tamiya 70225 Shaft Drive Unit provides a straightforward way for builders to explore gear trains and driveline concepts by building working 4WD models. Its design complements Tamiya Educational Construction components and supports a variety of small model configurations.

Key design and compatibility notes

Supplied as two complete units, the package includes hex shafts, mounting pieces and the internal gears required to construct a shaft-driven 4WD system. Clear axle housings reveal the gear operation so users can observe movement and understand mechanical interaction. Each unit can be flipped to alter rotation direction for different drivetrain setups.

Classroom and hobby applications

Ideal for group activities and solo projects, the drive unit helps illustrate mechanical principles through tangible builds. Combine it with universal plates and the range of wheels in the Educational Construction catalogue to test different vehicle styles and drive layouts.
