Albatros W.4 vs Arado SD I
Albatros W.4
The Albatros W.4 was a German floatplane derivative of the Albatros D.I fighter with new wing and tail surfaces of greater span than the D.I. One hundred eighteen examples (including three prototypes) were built between June 1916 and December 1917. The aircraft operated in the North Sea and Baltic theatres and later served as training aircraft. The W.4 was powered by the same 120 kW (160 hp) Mercedes D.III engine fitted to the D.I and based on the same fuselage. The first production series W.4s were armed with one lMG08 7.92 mm (.312 in) machine gun. Later aircraft carried two guns.

Arado SD I
The Arado SD I was a fighter biplane, developed in Germany in the 1920s. It was intended to equip the clandestine air force that Germany was assembling at Lipetsk. The layout owed something to designer Walter Rethel's time with Fokker. Of conventional configuration, the SD I featured a welded steel tube frame, metal-covered ahead of the cockpit, and fabric-covered aft of it. The wooden sesquiplane wings were braced with N-type interplane struts, without any wires - a typical Fokker feature. In flight, performance and handling proved disappointing at anything but very low speeds. Questions also arose as to the structural soundness of the design, and development was terminated very soon thereafter.
