A speed baris a system that allows the pilot to lower the angle of incidence of the wing by pulling down the leading edge. In doing so, the drag is decreased and the wing speeds up. As we can see, a paraglider is a quite complex wing and an experienced pilot has many means to tune the wing to the existing conditions.
A quadcopter, also called a quadrotor helicopter or quadrotor, is a multirotor helicopter that is lifted and propelled by four rotors. Quadcopters are classified as rotorcraft, as opposed to fixed-wing aircraft, because their lift is generated by a set of rotors. Quadcopters generally use two pairs of identical fixed pitched propellers; two clockwise and two counterclockwise. These use independent variation of the speed of each rotor to achieve control. By changing the speed of each rotor it is
