Human-powered helicopter breaks record with 50-second flight

The newest version of the craft weighs only 71 pounds, 30 less than the previous one, which stayed aloft for 11 seconds in 2011. Gamera II harvests power from arm movements as well as pedals, transmitting more power to the four large rotors.
