How difficult? The Sikorsky Prize from the American Helicopter Society has promised $250,000 to anyone that build’s a human-powered helicopter that can “hover for a minute, reach a height of 3 meters (about 10 feet), and stay in a 10-meter box.”
No one has claimed this prize in 30 years. And not for a lack of trying.
