Tamiya 70217 Flywheel Car Kit - Transparent Drive STEM Model  [70217]

Build and Explore with the Tamiya Flywheel Car

The Tamiya 70217 Flywheel Car Assembly Kit is a practical STEM build that helps users observe simple mechanical concepts in action. Its friction-powered design makes it suitable for demonstrations of stored energy and motion without electronics.

Transparent Mechanism Reveal

A clear drive housing shows the metal flywheel and its motion, giving a direct view of energy storage and release. When fully wound, the flywheel typically powers the car for about 20 meters or roughly 35 seconds, useful for timed experiments.

Pattern Cam Options

Included cam parts let you switch between zigzag and figure of eight movement patterns, plus a spare cam for custom routes. This lets users test how cam shape affects steering and pathing.

Easy Assembly and Controls

The kit assembles with a mix of snap-fit components and screws, so no cement is needed. The front wheel can be locked to force straight-line travel, which is handy for distance or speed trials.
