The wings, which could be folded upwards for transport and had no wire bracing, were made of wood covered with varnished paper and were of a complex design probably inspired by the seeds of the Zanonia tree. Remarkably for the time, the high-set wings were cantilever structures. Though the 1907 plan view much exaggerates the curvature, the wing leading edges did form a quarter of a circle, with constant chord out to large, curved edged tips with increased chord and dihedral.
