An aerial vehicle includes a fuselage, a wing, and a wing shift device. The wing shift device is configured to be coupled to the fuselage. The wing shift device comprises a plurality of apertures for coupling the wing to the aerial vehicle. The plurality of apertures are configured to permit the wing to be shifted in a forward or aft direction along the fuselage based on a center of gravity of the aerial vehicle.

A lift assembly that is releasably fastened to a fuselage of a rotorcraft. The lift assembly comprises a wing comprising at least two spars. A main gearbox passes through an opening in the suction side of a central box of the wing so that its bottom is attached to a resilient suspension system arranged level with the pressure side of the central box, a top of the main gearbox projecting from the central box and being fastened to at least one spar by at least three suspension bars. A reversible fastener system having a plurality of fastener means serves to fasten the central box reversibly to a plurality of fastener points of a fuselage.
