Abstract: A vertical take-off and landing aircraft includes a fixed wing airframe having opposed first and second wings extending from first and second sides, respectively, of a fuselage having opposed leading and trailing extremities, and a tail assembly located behind the trailing extremity. Vertical take-off and landing (VTOL) thrust rotors are mounted to the airframe providing vertical lift to the aircraft, and a forward thrust rotor is mounted to the airframe for providing forward thrust to the aircraft. At least one of VTOL thrust rotors is laterally tilted with respect to the airframe for providing vertical lift and yaw control authority to the aircraft.

Abstract: An aircraft motor includes a bearing assembly including a first plurality of rotor alignment magnets; a magnet support structure fixedly mounted on a shaft of the motor in a spaced apart relation to the bearing assembly, the magnet support structure including a second plurality of rotor alignment magnets such that when the vertical thrust engine is disengaged, attraction between the first and second rotor alignment magnets causes the magnet support structure to rotate relative to the bearing assembly to an alignment position defined by the relative placement of north and south poles of the first and second plurality of rotor alignment magnets.
