Tamiya 70238 Kayak STEM Electric Mechanical Kit  [70238]

Hands-On Paddle Mechanics with Tamiya 70238 Kayak

The Tamiya 70238 Kayak provides a tangible lesson in how rotary motion becomes paddling movement. The build encourages learning about linkages, crank action and basic marine propulsion while producing a display-ready model.

Motion system and drive

When assembled the kayak measures 210mm by 200mm by 105mm. A compact underwater gearbox together with a submarine motor mini transfers power to the paddle via a crank and connecting rods, producing a convincing paddling cycle for demonstration or play.

Tuning for handling and presentation

Paddle blade angle adjustments allow you to change how the model tracks in the water, giving basic steering control. The package features a PE foam piece that aids flotation and doubles as a display stand. Rubber rings enhance paddle longevity and water-resistant decals let you personalise the hull.
