Broad, lobate ailerons were hinged at right angles to the line of flight, protruding beyond the trailing edges and carrying small trim tabs not fitted to the Storch IV.

[1] Broad, low endplate fins and rudders of about equal area, cambered on their inner surfaces provided directional stability and control.

[1][2] Each wing was braced from a single point on the lower fuselage pod longeron to nose and rear spars at about 40% span by a faired V-strut.

The pod was flat sided, with angled upper and lower surfaces and on the Storch IV projected back almost to a line between the aileron trailing edges to provide some yaw stability.

[1] On the Storch V this provided a place to mount a small DKW 5–7 kW (7–9 hp) air-cooled two-stroke engine in pusher configuration with its output shaft just lower than the wing.
