A hybrid unmanned aerial vehicle (10) is provided which comprises a multicopter frame (14) having a plurality of operable multicopter propulsion units (22) thereon, and an airframe body (16) which is connected to the multicopter frame (14). There is also a pair of wings (34) positioned on opposite sides of the airframe body (16) and a wing control means for manipulating the pair of wings (34) with respect to the airframe body (16) to alter an angle-of-attack of the pair of wings (34). In a first wing condition, the angle-of-attack of the pair of wings (34) is alterable with respect to a relative airflow so as to produce zero lift, and, in a second wing condition, the angle-of-attack of the pair of wings (34) is alterable with respect to the relative airflow so as to produce an optimum or near optimum lift. A method of improving the manoeuvrability of the hybrid unmanned aerial vehicle (10) is also provided, as is a method of improving the operational range of unmanned aerial vehicles.
