Abstract
A hand launched glider of folded sheet material, having a basic fuselage with integral tail surfaces and a curved slot to hold a wing which is keyed to the fuselage to maintain alignment, the wing being adjustable fore and aft in the slot. The central fuselage and nose portion are reinforced by additional folded elements, one of the elements comprising a slidable locking member which secures the wing at any selected position in the slot. A spring clip on the nose secures the multiple elements in place, including the wing locking member, and also serves as ballast for balancing the glider. The wing and tail have adjustable control surfaces which, together with the wing position adjustment, provide a wide range of flight control.
