I came across this video on my youtube feed today. How is this kind of endurance possible with standard LiPos? The last best flight time of 45 min was achieved by Holger Buss with his hexa mikrokopter if I'm not wrong. Can anybody shed light on how microdrones managed in excess of an hour?

I reckon 12 hours was better. But sort of cheating of course.

...low C rated LiPo batteries too, 4-6C are much lighter than the 20-40C's we use
They are also running 12.2Ah and 18.3Ah (depending on model) Lipo batteries. Those are 6 times larger than what is typical used on most quadcopters.
Very efficient motors, coupled with the optimum size propellers for this motor speed. Hovering only, will save on batteries. And they probably chose the best battery, with the best life out of the batch.
This is a record attempt with no wind, like outdoor flying has.
