 The lower wing, which carried dihedral was fixed to the lower fuselage with a thick wing root, but the upper one was high above the fuselage at its centre, supported by pairs of N form cabane struts.The interplane struts were streamlined and broad in chord, made from duralumin; there was a pair of these struts marking the inner bay but a single strut outboard.The wings, made of wood and fabric covered were of constant chord over most of the span, but final sections where the leading edges swept back produced triangular tips.
