In an attempt to speed up the Siemens-Schuckert D.III
and reduce its cooling problems, the Siemens-Shuckert D.IV
featured a reduced-chord wing and a cut-away engine cowl (which was also used on late-model D.IIIs). The D.IV attempted to increase the D.III's speed with narrow-chord wings, which reduced drag at the cost of decreased climbing capability. Though seen only in small numbers, it was probably the best German fighter at the end of the war, from a technical standpoint.
The D.IV has an unusual feature: the left wings are some 7cm longer than the right to compensate for propeller torque.
This product comes in two scales: 1:144 and 1:285/6mm/1:288. At 1:285 there are two aeroplanes.
They come with a seperable, translucent propeller disk rather than propeller blades, which are difficult to print at this scale. They are joined by disposable links to keep the price down, since single-part models are more affordable. You can break the links with nail clippers, wire cutters, or similar.
