This invention relates to a vertical take-off and landing (VTOL) aircraft, a method of controlling a VTOL aircraft, and a control system for controlling the VTOL aircraft. The aircraft comprises an airframe having a wing extending along a transverse axis and attached to a fuselage extending between a longitudinal axis of the aircraft, and an empennage or canard. An array of electric rotors is fixedly mounted to the airframe. Front and rear internal combustion engines are pivotably mounted to the fuselage and are displaceable between lift positions in which the front and rear rotors are oriented to provide vertical lift to the aircraft for vertical flight and propulsion positions in which the front and rear rotors are oriented to provide forward thrust to the aircraft for horizontal flight. The front and rear rotors provide a majority, or all, of the vertical lift to the aircraft during vertical flight.
