The tail rotors make me think the aircraft is tail heavy which means it will be unstable in horizontal flight.

All modern aircraft are “unstable in forward flight” in pitch.

This is more efficient than stable aircraft. The horizontal stab creates lift taking load off the wing (versus a stable aircraft where the stab creates negative lift and the wing has to generate even more lift to compensate).

Gyro’s and computers make them stable. $75 RC models have this same technology, now... you can put the CG at 50% MAC and they’ll fly great. Don’t try that with out a gyro.

Wing is swept, so when you stand it up on edge for hovering the center of lift would move forward.

If they work the bugs out, I suppose you'll see these hovering over every demonstration taking pictures or dispensing tear gas...
