The blade span of 34cm makes it look impressively large once assembled, and it actually spins in a gentle breeze. I was surprised how quickly the LED lit up when I took it outside. It’s a solid, hands-on way to show how wind power works.

My kids built it in about twenty minutes and were thrilled when the blades spun and lit the LED on a breezy afternoon. The 34cm blade span makes it big enough to actually see the mechanics working, which is perfect for a classroom demo or rainy day project.

My son was thrilled to see the 34cm blades spin in the breeze and actually light up the LED. The build itself was straightforward, though the nacelle is a bit fiddly to keep steady. It's a neat, hands-on way to understand wind power.
