A process for creating playthings that fly, and airplanes in particular, that unites extreme lightness with considerable tensile strength, both for the individual component parts and for the assembled model. The said process is constituted by a number of stages that comprise: the production, through the punching of extruded polystyrene, of one or more members of limited thickness and of suitable shape that constitute the fundamental parts of the toy; the production of a pair of facing members, of a shape and an outline corresponding to that of each limited thickness member; and finally, the fixing of the said pair on both sides of the said members of limited thickness, so that the outline thereof is fully covered. |
