fuselage wings are wings that can be changed like wings and like fuselage blocks. Fuselage wings will help plane makers A LOT because as of now they have to put in a normal wing, put fuselage blocks over it, and then make working fuselage flaps with hinge rotators. I say no more of that stress. By the way, they have to do that whole process with EVERY WING. But yeah, you get what I mean.
