Never saw horizon quadcopter in the air.
OK, seems real: www.hes.sg
Strange. I thought the fuel cell need to be bigger to deliver as much current as needed...
Actually, it looks like they've recently broken their own record:
ENERGYOR DEMONSTRATES MULTIROTOR UAV FLIGHT OF 3 HOURS, 43 MINUTES
Was that flight time *with* a 1kg payload? If so, then it is impressive.
