Tamiya 70218 Manta Ray Swim Kit - STEM Build  [70218]

Tamiya 70218 Manta Ray Swim Kit Overview

The Tamiya 70218 Manta Ray Swim Assembly Kit gives hobbyists and young builders a practical way to explore STEM ideas through a hands-on construction project. The flexible fin recreates a manta ray's swimming motion and is driven by a small submarine motor, making this kit suitable for display or simple experiments in motion.

Movement and Build

Measuring 160mm long, 148mm wide and 55mm high, the Manta Ray Swim Assembly Kit is scaled to show realistic fin motion. The straightforward build process keeps the kit accessible to newcomers and experienced tinkerers alike. The fin is driven by a submarine motor via a connecting shaft, while the tail fin serves as a rudder so you can change the travel direction.

Hands-on Learning

This kit is useful for learning core mechanical ideas like propulsion and linkages. Assembling the parts and running the model demonstrates how mechanical elements create motion and how a simple electrical circuit powers the motor. The motor runs on one AAA battery, highlighting basic power integration.
