well sure, but you do agree that any kind of deflection of the rear
with such a long fuselage
works like a big f'ing lever that twists the connecting point.. right?

It's like twisting somebody's arm , it doesn't matter how big his biceps is, if you got him at the right end and pull in the wrong direction.. it's gonna hurt.

Now I suppose having the wing in the middle of the fuselage, with a nose section almost as long as the tail will help in that respect. Like a counter weight..
the tail is like 25-30 meters... and the those elevators can exert quite some force..


But I doubt this plane is going to be flying in any kind of stormy weather, I wouldn't want to be on it in heavy turbulence...
