LFG Roland D.II
The LFG Roland D.II was a German single-seat fighter of World War I. The type was manufactured by Luftfahrzeug Gesellschaft, and also by Pfalz Flugzeugwerke under license. Design and development. The D.II used a plywood monocoque fuselage. Two layers of plywood strips were spirally wrapped in opposing directions over a mold to form one half of a fuselage shell. The fuselage halves were then glued together, covered with a layer of fabric, and doped. This design was known as the "Wickelrumpf" and allowed to create a smooth, strong and light structure. The upper wing was attached  to the fuselage by means of a large central pylon, greatly impairing the pilot's forward vision. Armament consisted of twin "Spandau" LMG 08/15 machine guns buried in the fuselage decking. The D.II was initially powered by a 160 hp Mercedes D.III engine, giving a top speed of 105 mph at sea level. Later aircraft, designated D.IIa, were powered by a 180 hp Argus As.III. The As.III offered poor performance above 3,000 m and the D.IIa was mostly relegated to operations on the Eastern Front. Nicknamed "Haifisch" (shark) for its sleek appearance, the D.II and D.IIa proved generally  unpopular in service due to poor fields of view and heavy controls. It was quite fast and strong, but had mediocre manoeuvrability and handling. However, it is also reported that the aircraft had particularly sensitive controls, particularly in the yawing plane. The type is known to have been used by "Jasta" 25 at their Canatlarzi base in Macedonia in 1917.
