Tamiya 70218 Manta Ray Swim Kit - Entry Level STEM  [70218]

Tamiya 70218 Manta Ray Swim Model Summary

The Tamiya 70218 Manta Ray Swim Assembly Kit offers a compact project for model builders who want to see how fin motion creates propulsion. The flexible fin design copies the swimming action of a manta ray and is powered by a small submarine motor for smooth movement in water.

Build Notes and Performance

At 160mm long, 148mm wide and 55mm high, the kit is scaled to display the fin's sweep. The build is straightforward and friendly to first-time constructors, with the motor linked to the fin by a shaft and a tail fin that works as a steering rudder.

STEM Takeaways

Assembling this kit illustrates mechanical principles like thrust and control, and shows how a simple circuit powers a motor. Operation requires one AAA battery, making it easy to power and test without complex electronics.
