Tamiya 70218 Manta Ray Swim Model - STEM Series  [70218]

Tamiya 70218 Manta Ray Swim Assembly Overview

The Tamiya 70218 Manta Ray Swim Assembly Kit is a compact educational model that combines simple mechanics with hands-on construction. Its flexible fin mimics the sweeping motion of a manta ray and is turned by a compact submarine motor, making the kit suitable for display or basic experiments.

Construction and Motion

The model measures 160mm long by 148mm wide by 55mm high, a size chosen to clearly show the fin action. The assembly steps are straightforward so builders at varied skill levels can complete the kit. The motor drives the fin through a shaft, while the tail fin provides rudder control for steering adjustments.

Learning Outcomes

Building the kit offers practical lessons in propulsion, motion and simple electromechanics. Fitting the motor and battery shows how a basic circuit powers a moving part. The kit requires one AAA battery for operation.
