The Schlesierland's wing is held above the fuselage on a pedestal and braced by a single lift strut on each side from the lower fuselage longeron to about one quarter chord. The wing is built around a single spar and plywood covered ahead of it around the leading edge, with fabric covering behind. The central third of the span is a rectangular panel, within which a diagonal sub spar runs rearwards from the main spar, with additional ply covering ahead of it. Originally there were no control surfaces on this inner panel, though in 1941 airbrakes were added across the junction between inner and outer panels, mounted behind the main spar. The outer panels taper strongly with sweep on both edges, ending in elliptical tips; the broad ailerons, which occupy about half the span and, at their inboard ends, about half the chord, are also tapered though less strongly than the wing.
