Abstract: A kit of parts and a method for converting between a glider and a kite. The kit of parts includes a body, a kite wing and a glider wing. The kite wing is removably connectable to the body so that the body and the kite wing can be connected to a kite string and flown as a kite. The glider wing is removably connectable to the body so that the body and the glider wing can be flown as a glider.

Abstract: In one aspect, the invention relates to a payload transfer and release system for a kite including a potential energy storage unit for releasably storing potential energy, a launcher, a receptacle, an optional payload and an optional stopper. The potentially energy storage unit is, in one embodiment, an elastic band. The launcher includes a body which has a hook to which the launcher mounts. The receptacle is for holding a payload and has an outlet for releasing the payload. The receptacle has at least one mounting connector for slidably connecting the receptacle to a kite string, and a receiving portion for releasably receiving a portion of the elastic band. In use, the receptacle holding the payload can be launched to travel on the kite string. The receptacle can be stopped by the stopper, at which point, the payload leaves the receptacle.

Abstract: An improved shape-retaining support structure is provided for the fuselage of a windsock style kite. An inextensible strap member is also provided between the wings of the kite to transfer wing loads through the windsock body without distorting its shape.
