The sports aircraft SAI KZ II is a two-seat, single - engine low - wing aircraft from the Danish manufacturer Skandinavisk Aero Industri . The abbreviation KZ refers to its designers Viggo Kramme and Karl-Gustav Zeuthen. The first flight took place on December 11, 1937. The machine has a partially covered, fixed chassis with a spur.
There are three variants of this series:
KZ II Kupé
This two-seater sports machine had a hull made of steel tubes that was planked with plywood and fabric. The wing was made of wood and also covered with plywood and fabric. A total of 14 pieces were produced between 1937 and 1940. The wings could be folded onto the fuselage for better transport and to reduce the floor space. The two seats were next to each other in the fuselage in a closed cockpit.
Three machines of this type have survived. One of them is ready to fly at Dansk Veteranflysamling , Skjern , Denmark.

KZ II sports
The sport variant of the KZ II differs from the Kupé mainly in its open cockpit with the seats one behind the other. The smaller frontal area combined with the more powerful engine enables better performance. The first flight of this variant took place on October 10, 1938. A total of 16 machines of this type were built. However, all machines were confiscated by the German occupiers .

Concentration camp II Træner
The trainer is a reinforced variant of the KZ II Sport. After the Second World War, the Danish Air Force quickly needed re-trained pilots, so a number of these types were procured. The first flight of the prototype took place in April 1946. Fifteen machines were ordered that were used for pilot training as early as autumn 1946. The machines remained in service until 1955. The nine aircraft, which were still clear to fly, were then sold to private owners.
