A remote-controlled helicopter, powered by the wind? Well, not exactly. This wind-powered helicopter is more kite than copter, and it needs a pretty stiff wind of at least 13mph to stay aloft.
It does use the same lift principles as helicopters, though. You start its rotors spinning so the craft can lift off, and then you're holding its string and flying it like a kite. With Spring on the way, this might be a good way to celebrate the upcoming thaw, if it ever arrives. It's available now for about $30.
