Abstract: In a vertical take-off and landing vehicle, the invention is a method for improving stability by virtue of establishing conversion of thrust vectors over the center of gravity of the vehicle while in the hover position. Through the use of selected angles of inclination of the thrust-generating devices, a positive static stability of the aircraft is maintained. In addition, the spars supporting the thrust-generating devices are mounted in a fixed angular relationship to the centerline of the aircraft's fuselage, to achieve the desired inclination of the thrust vectors of the lift-generating devices toward the centerline of the vehicle, by simple rotation of the spars on which the lift-generating devices are mounted.
