This perspex helicopter has a fully working rotor, powered by its own solar panel. Made from thin gauge laser cut clear acrylic, which easily clips together without the use of solvent glue. This solar powered helicopter kit is a great demonstration of how efficient modern solar cells are. It is able to fully power up with just the light from a desk lamp. I think it would be even more impressive if it were able to fly. Great fun none the less and educational, it could also be personalised with vinyl graphics and used as a promotional item, a unique desk ornament. I want one!
