Looks weird;it's bulky,has small landing gears&4small engines with 2-blades.

Very strange claim:

"..With a 12-20 hour endurance, 370 kmph speed and 200 km range.."

Range optimised speed/altitude is not really endurance optimised speed/altitude, it means it can 'fly' at a speed of no more than 10 km/hr...about that of a bird

Apparently the stalling speed is related to the wing loading(weight divided by wing area)..lower wing loading⇒lower stalling speed.... the smaller the flying object, (by simple math) naturally the lower is the wing loading...insects can fly very slowly.

"..The slowest flying speed of human powered glider(which apparently has very low wing loading)is 13km/hr..."

"..Woodcocks – both American and Eurasian – hold the honor of being recognized as the world’s slowest flying birds, recorded flying at the “sloth-like” pace of 8 km/h (5 mph) during courtship displays..."
