A fixed-wing, fixed-rotor vertical-takeoff and landing (VTOL) unmanned aerial vehicle (UAV) may include a fuselage extending from a fore portion to an aft portion and defining an upper section and a lower section, a first pair of airfoils fixedly attached to opposite sides of the fore portion of the fuselage, and a second pair of airfoils fixedly attached to opposite sides of the aft portion of the fuselage. The first pair of fixed airfoils may be offset relative to the second pair of fixed airfoils in the upper section-lower section direction. In some examples, the first pair of airfoils defines a first airfoil pair surface area different than a second airfoil pair surface area defined by the second pair of airfoils so the first and second pairs of airfoils generate lift that urges the VTOL UAV from a substantially vertical orientation during takeoff to a more horizontal orientation during flight.
