Abstract:
A multirotor aircraft that includes a chassis, at least three engines that 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.

Claim (Index 4):
The multirotor aircraft according to  claim 1  that includes at least four engines; wherein said chassis includes a main body, a pair of right shafts and a pair of left shafts; wherein each of said propellers is attached to the end of each of said shafts; and wherein at least one of said pair of shafts is connected to the main body by an axial connection; wherein when increasing power of one engine which is connected to the main body by said axial connection then the pair of shafts of said engine are twisted relatively to the main body and rotate the multirotor aircraft on its perpendicular axis; whereby enabling to rotate the multirotor aircraft and to nullify undesired rotations of said multirotor aircraft.
