A multi-airfoil element wing includes a central single-airfoil element and an outer dual-airfoil element positioned outboard of each side of the central single-airfoil element. The single-piece member defines aerodynamic surfaces of the central airfoil element and both of the outer dual-airfoil elements. The single-piece member includes a carbon fiber resin hollow body forming at least a portion of the central single-airfoil element and of both outer dual-airfoil elements.
