The invention relates to a system for landing UAV's. The system comprises a slingshot structure that includes arm based structure and an axis installed along the arm of the structure and enabling the arm to move around it. The system comprises a base connecting the axis to a platform at which the system is installable. The system also includes a controlled pulling and braking means that connects the arm of the structure and the platform upon which the system is installable and stretchable elastic installed in a stretched manner at a gap formed between two arms and set to connect with a landing UAV. At the landing phase, the controlled pulling and braking of the system essentially breaks the motion of the arm based structure that is propelled to revolve around the system's axis, and propels the structure to move around the axis.
