Tamiya 70178 Submarine Motor Mini Learning Kit  [70178]

Tamiya 70178 Submarine Motor Mini for Introductory Engineering

The Tamiya 70178 Submarine Motor Mini is crafted to make core mechanical concepts tangible. As an entry-level STEM model, it clarifies how propulsion and rudder control affect movement in water.

Clear Demonstration of Thrust and Steering

The kit houses a small motor in a durable blue casing that spins a rear propeller and operates a rudder. Builders can observe how thrust and rudder position combine to change direction during short water trials.

Fast Assembly and Safe Activation

Construction is straightforward and needs no specialist tools; the motor only powers up when the outer shell is fully closed to reduce accidental starts. A suction cap is included for quick fixing to flat surfaces.

Ideal for Beginners

Designed mainly for educational use, the Submarine Motor Mini doubles as a first model build for younger hobbyists. It uses one AAA battery, which must be purchased separately.
