A multirotor aircraft that includes a chassis, at least three engines that are equipped with propellers, and a free wing that is axially connected to the chassis. The attack angle of the free wing is changed relatively to the chassis due to flow of air. When the aircraft is hovering then the free wing is free to rotate, when wind flows over the wing during hovering then the tilt angle of the wing is changed by forces of the wind to a position in which a drag force on the wing is reduced, and by that enables a precise hovering relative to a ground point and precise control over the aircraft. The free wing provides lift force in horizontal flight and in situations of front horizontal wind during hovering and by that reducing the amount of energy required to operate the aircraft.
