Tamiya 71114 Mechanical Blowfish Educational STEM Kit  [71114]

Explore Linkage Motion with the Tamiya 71114 Mechanical Blowfish

The Tamiya 71114 Mechanical Blowfish is designed to demonstrate fundamental mechanical principles through an aquatic model. It is ideal for enthusiasts who enjoy building and observing practical motion systems.

Visible Crank and Link Mechanism

The kit uses a crank with a connecting rod to swing the tail fin, producing a natural swimming action. The clear green upper shell provides a view of the internal parts, while the lower white shell houses the motor, gearbox, battery compartment, and a sealed switch.

Designed to Resist Water Entry

Protection against water is provided by waterproof tape and rubber O-rings at sensitive points such as screw holes, the on/off switch, and the tail joint to help keep the internals dry during operation.

Simple Tail Adjustment for Directional Control

Adjust the swimming direction by rotating the stopper at the tail root to the left or right. The tail is straightforward to trim, so you can test how different shapes affect straight-line speed and turning.
