A hand launch glider which includes the use of a fuselage and a wing and an empennage, the fuselage constructed of laminated polystyrene plastic layers bonded on each side of a thin balsa wood core, both the wing and the empennage including connecting means to readily fix the position of each with respect to said fuselage so that the operator will readily know when either the wing or the empennage is misaligned with respect to the fuselage.
