Tamiya 70238 Kayak STEM Mechanical Series Kit  [70238]

Educational Kayak Model Tamiya 70238

The Tamiya 70238 Kayak kit is aimed at hands-on learning, showing how simple mechanisms create natural paddle action. It is suitable for hobbyists who want a compact, working model that explains basic propulsion concepts.

Drive components and scale

The finished model spans 210mm in length, 200mm across and reaches 105mm in height. Power is transmitted by a compact underwater gearbox and a submarine motor mini to a crank and link rod setup that moves the paddle in a realistic stroke.

Display options and adjustments

Adjusting the paddle blade angles changes the kayak's direction for practical experimentation. A PE foam insert provides buoyancy and serves as a stand for shelf display. Rubber rings protect the paddles and the kit includes durable water-resistant stickers for finishing touches.
