Tamiya 70224 - Swimming Dolphin  [70224]

Tamiya 70224 Swimming Dolphin Model Kit

The Tamiya 70224 Swimming Dolphin model kit is part of Tamiya's renowned STEM series, providing an engaging platform for hobbyists to explore basic mechanical principles through hands-on assembly. This kit constructs a motorized dolphin that swims using a unique underwater gearbox, making it an excellent choice for those interested in educational modeling experiences.

Design and Functionality

The model measures 182mm in length, 100mm in width, and 60mm in height, offering a compact yet detailed build. The dolphin's motion is powered by a submarine mini motor, requiring one AAA battery (not included), which drives a crank mechanism to move the tail fin up and down, propelling the model forward while the head bobs realistically.

Material and Build

Constructed from springy polypropylene (PP) sheets, the dolphin's body and fins are designed to mimic natural movement, providing a smooth and lifelike swimming action. The kit includes a float attached with a suction cup, allowing the model to maintain buoyancy in water.

Educational Value

This model serves as an accessible introduction to mechanical assembly, suitable for younger modelers with guidance. By adjusting the fin position, users can change the swimming direction, offering a practical demonstration of basic mechanical concepts.
