A flying vehicle assembly apparatus comprises a winged flying craft and a powered craft comprising two or more hulls for propelling the flying craft, and a biased tether assembly comprising one or more first rigid struts having a first end pivotally secured to pivot connections adjacent to the flying craft and a second end pivotally secured to a hinge assembly, and one or more second rigid struts having a first end pivotally secured adjacent to the powered craft and a second end pivotally secured to a biased hinge assembly. The biased tether assembly urges the flying craft and the powered crafts toward one another whereby at least a portion of said powered craft is beneath the flying craft, and whereby during flying operation, the powered craft is generally forward of the flying craft.
