The Tamiya 70179 Submarine Motor Mini is part of the Educational Construction Series and is designed for learners exploring basic physics and buoyancy. The package includes the motor plus a 6mm thick styrofoam float, making it suitable for quick bench trials and club demonstrations.
Use this kit to run simple experiments in propulsion and balance in water. Builders can try different hull shapes and float placements to see how changes affect trim and movement, and it pairs well with 1/700 Waterline Series models for integrated displays.
The unit uses a single R3/AAA/UM4 alkaline battery (sold separately), keeping setup minimal for field testing. Its compact form makes it easy to add into other Tamiya constructions or custom hobby projects.
