The disclosure provides a method of controlling the yaw of a fixed-wing UAV, with two propulsion propellers arranged parallel to each other and providing thrust for the UAV; A plurality of motors configured to drive the two propulsion propellers, wherein the thrust ratio provided by the two propulsion propellers is changed to generate asymmetric thrust which controls the active yaw of the UAV. The fixed-wing UAV provided by the disclosure improves the reliability of the thrust system and active yaw.
