Moldless composite construction methods, utilizing shaped foam cores with composites skins and other built-in structural components, are used extensively by homebuilders in the construction of experimental aircraft using commercially available designs. Analyses of these designs are not readily available to the homebuilders. Finite element models of the canard and main wing were used to analyze a design for a homebuilt aircraft. Wings were built using both the fiberglass 'plans' design and an optimized design which utilized carbon fiber composites in high stress areas to minimize weight and increase stiffness. Associated costs and performance of the standard and redesigned wing structures are discussed.
