History
It grew from a design study by Gösta von Porat, developed by Henry Kjellson at FVM and powered by a Le Rhone-Thulin rotary. It first flew in June 1920 with von Porat at the controls, and was originally the E.1.
Variants
There were no major variants. A replica built in the 1980s with an original Thulin engine has flown at displays in Europe, North America and Australasia.
Where you'll see it
28 were built and served as advanced trainers until 1935. The Air Force designation Ö 1 was adopted after the Air Force formed in 1926.
