Created by Saba Modellbau team, from Germany, this is the paper model version of the Fieseler Fi 158, an experimental aircraft of which very little is known. Only one aircraft was built around 1938 (the construction of a second cell was terminated early in the morning). The Fi 158 was characterized by very clean lines and to be extremely motorized for such a small aircraft (160 HP Hirth engine). In addition, it was the only Fieseler aircraft with retractable landing gear. When printed in A3 format, the model is in 1/33 scale.
