Tamiya 70238 Kayak: Practical STEM Kit

The Tamiya 70238 Kayak is a compact assembly model that illustrates how simple mechanisms convert motor rotation into paddle strokes. It is a useful learning tool for anyone curious about linkage motion and basic propulsion.

Authentic stroke motion

The assembled kayak measures 210mm long, 200mm wide and 105mm tall. It employs a compact underwater gearbox combined with a submarine motor mini to drive the paddle through a crank and connecting rods, producing a lifelike paddling motion for testing and display.

Steering and presentation tweaks

You can modify paddle blade angle to affect steering and behaviour on the water. The included PE foam section provides flotation and doubles as a neat display base. Paddle durability benefits from rubber rings and the kit comes with water-resistant stickers for customised looks.
