D-EPWD
The Fi99 "Jungtiger" was supposed to be a pure sport aircraft . Based on the experience gained in the development of the F5 aircraft, the seats on the new aircraft were arranged in a row, one behind the other, and were completely covered by the roof. The Fi99 was produced, however, only in small numbers in 1937-1938, although it was an aircraft of very good performance.

It also deserves mention that the Jungtiger was tested for towing on a drawbar. This could only be allowed with aircraft that showed completely non-critical flight qualities. With an HM 506 A engine from Hirth with a power of 160 hp. "Jungtiger" developed a maximum speed of 236 km / h. The design of the aircraft was wood-metal. The fuselage consisted of a frame welded from metal pipes with side forming strips and fuselage parts lined with plywood. The engine hood was made of aluminum, the wooden stabilizer was lined with plywood and fixed with struts from the fuselage side.

At the same time, the vertical tail was a frame made of metal pipes covered with fabric with extensions to the horizontal tail. All rudders were made of wood and covered with fabric.

The two-section wing was made of wood, in a two-spar design. Up to the rear spar, it was lined with plywood, and the rest - with fabric. Under the fuselage, up to the place where the wings were attached
, there were two retractable landing flaps that served as a take-off and landing device. Well sheathed chassis with suspension struts was equipped with mechanical brakes.

Initial versions had a sliding tail skid, and later aircraft received a fully rotating tail wheel. In emergency situations, it was possible to dump the entire cabin.

The color of the aircraft was, as was then customary in RLM 63, gray. The engine hood and identification were black. The stripe of nationality on the vertical plumage is red with a white circle.
