The Tamiya 70154 Submarine Motor with Boat brings mechanical and electrical fundamentals into a simple buildable form. It is a hands-on way to observe how a motor produces thrust and how hull design affects buoyancy and stability.
The kit supplies a submarine motor that fixes to the supplied polystyrene hull by means of a suction cup, allowing quick fitting and removal. The hull is receptive to basic decorating and trimming, so modders can experiment with balance and appearance while learning assembly techniques.
Power is from one R6/AA/UM3 battery (not included), making the kit convenient to run while illustrating energy conversion and simple circuit basics. It is well suited to solo hobby projects or guided learning sessions.
