[1] The Grüne Post had a constant chord, unswept wooden wing built around two spars and fabric covered except at the leading edge, which was plywood skinned.

The forward half of the fuselage was built on a 610 mm (24.0 in) wide V-section platform, Zögling-style but with sloping side covering, onto which the controls and the single seat, with its back on the wing pylon, were mounted.

From each side of the platform a pair of streamlined, parallel lift struts braced the wing at about mid-span.

[1] The Grüne Post had a near rectangular horizontal tail of constant chord and slightly angled tips.

[1] The plans spread widely: two Grüne Posts were built in Hungary[2] and one in Latvia.
