It can fly for 6 minutes, it is said somewhere in the videos. At 1,1kg the fuel cell is pretty heavy, it can be made much lighter.

By the way, the pictures are not mine, they were made by Paul-Henri Tirtiaux & Patrick Bossin from Belgium. Unfortunately, I could not visit the Aspach electric event, my back is giving me troubles (that's what you get when you're over 2 meters (6'7") and over 44 ), I could not drive the 450km. Next year ...
