Bucker Bu-181 Bestmann
Hägglunds & Söner Bü 181
The Bu 181 low-wing monoplane trainer was a development of the Bu 180 Student with enclosed side-by-side accommodation for the crew of two and typical mixed construction (ply/fabric-covered wooden flying surfaces, aluminium alloy covered steel tube forward fuselage and wooden monocoque rear fuselage) with fixed tailwheel landing gear. The production version for the Luftwaffe was the Bu 181A of which several thousand were built in Germany. More production was undertaken in Holland (708) and Sweden by Hägglunds & Söner (125 Sk 25s) during and just after the war, while post-war production was launched in Czechoslovakia and, under Czech licence, Egypt. The final war-time development was the Bu 181D with a number of detail improvements over the Bu 181A. In addition to its designed role, the Bu 181 was used as a communications aeroplane and, in small numbers, as a tug for light training gliders.
Heliopolis Air Works in Egypt was formed 1950 to manufacture a local version of the German Bücker Bu 181D Bestmann as the Gomhouria trainer for Egypt, Jordan, Libya, Saudi Arabia, Somalia and the Sudan.
A derivative was built as the Zlin 328.
