A tail sitting VTOL aircraft with nonplanar tandem rotor blown wing configuration, capable of traveling in an airplane mode, and a hover mode during take-off and landing with fuselage oriented vertically, with capability to have precise controlled hover, and capability of making controlled and safe assisted transition between two modes during a horizontal movement and without need for much headroom and overhead clearance. The aircraft includes a fuselage, a nonplanar wing configuration which includes plurality of wings in different planes and at least 1 stabilizer, the wings having a leading edge defining the forward direction of flight in airplane mode, and a trailing edge, and at least 1 proprotor connected to the airframe through a rotatable drive shaft, plurality of rotor blown surfaces with various orientations may be used to provide high precision hover and controlled assist during transition. Embodiments with at least 3 proprotors may also have multirotor capabilities in hover mode. Transition from hover mode to airplane mode is performed by moving forward in hover mode and rotating the fuselage around the pitch axis by the assist of the moment created by the differential thrust of the propellers, or the lift created by the rotor blown tandem airfoil-shaped cross section bodies or a combination of both.
