Abstract: A multirotor aircraft that comprises a body, at least three motors and at least one wing that is connected to the body. The wing is designed to be folded and unfolded during flight of the multirotor aircraft and designed to change during the flight a low-drag creation position to a lift creation position, and vice versa. At least one motor has a greater motor power than another motor and the distance from the strong motor to the center of gravity of the multirotor aircraft is shorter than the distance from the another motor to the center of gravity. The wing is positioned in the geometric area between the motors.

Abstract: A multirotor aircraft that includes a chassis, vertical rotors, foldable wings, and a means for deploying and folding the foldable wing. The foldable wing is attached to the chassis and the means for deploying and folding the foldable wing is designed to deploy and open the foldable wing from a folded and closed state to a deployed and opened state, and vice versa. The gravity center of the folded wing in a folded and closed state is near and close to the gravity center of the multirotor aircraft, and by that enabling to fold and close the foldable wing when hovering, landing and during takeoff and to deploy and open it when flying forward.

Abstract: A multirotor aircraft that includes a chassis, three or more vertical rotors, one or more free wings and on ore more fixed horizontal rotor. The free wing is attached to the chassis by an axial connection so that the angle of the free wing is changed relative to the chassis according the flow of air over the free wing. The fixed horizontal rotor enables the multirotor aircraft to lower and climb while flying forward at a stable horizontal pitch of the chassis.
