Interesting research. Assuming that the benefit of fixed-wing aircraft is efficiency in relatively straight flight, I'm wondering how this aircraft compares in efficiency vs agility against a quadcopter of similar weight.
Very neat to watch, I'd be curious to hear under what conditions it's worse than a quadcopter, perhaps stability or how quick it can turn.
Well, a quadcopter can fly with one busted motor/prop, this thing probably can't.
Winged flight is definitely for superior distance and loiter times.
Another obvious drawback would be more surface to get buffeted by wind when in hover.
