An aeronautical apparatus is disclosed that has two pairs of wings: an aft pair and a fore pair. Each wing has a thrust-angle motor. An assembly is coupled to each thrust-angle motor. Assemblies coupled to the wings have a propeller motor with a propeller and a control surface. The control surface provides lift when in forward flight. In vertical flight or hovering, the control surface, if it remains fixed with respect to the fuselage, i.e., in the position which provides lift in forward flight, produces significant drag. However, by rotating the control surfaces with the propeller motor, the drag from the control surfaces is significantly reduced. The control surfaces are outboard the propellers in some embodiments and inboard in others. In the latter case, the control surface is part of the trailing edge of the wing. |
