A folding multi-rotor VTOL aircraft is described that stows the rotor propulsion system in the region above the fuselage and fit within the length and width of the fuselage footprint. The folding members supporting the rotor propulsion units then fit within the regions between the stowed rotor diameters. The members are of sufficient length that when unfolded to operational configuration the slipstream of the rotors do not impinge on the fuselage. Overall aircraft height includes the fuselage, the stowed rotors, and a powered landing gear that provides ground mobility and short take-off and emergency landing capabilities. The overall height is minimized by a compact rotor system and low or adjustable landing gear ground clearance. The rotor propulsion units may incorporate ducts that are specially designed to produce improved lift.
