Tamiya 70238 Kayak Build Kit for STEM Learning

The Tamiya 70238 Kayak kit gives a practical introduction to movement mechanics through assembly and testing. Builders get a clear view of how link rods and crank action translate motor output into paddle motion.

Scaled mechanics and motion

The finished model measures 210mm long, 200mm wide and 105mm tall. It uses a compact underwater gearbox paired with a submarine motor mini to drive the paddle through a crank and link rod arrangement, recreating natural paddling action for study or display.

Adjustable paddle and display features

Paddle blade angles can be adjusted to influence steering, adding an interactive tuning element. A PE foam stabiliser keeps the kayak upright in water and doubles as a display stand. Rubber rings protect the paddles and the kit includes water-resistant stickers for custom finishes.
