General Characteristics
The FVM Ö1 Tummelisa (Swedish for “Thumbelina”) is a light, single-seat biplane from the 1920s. It was the most well-known and successful aircraft designed by FVM (Flygkompaniets Tygverkstäder på Malmen), the Swedish Army Aviation’s workshop. The aircraft was developed for advanced training, particularly for prospective fighter pilots, and was praised for its agility, though it demanded skill due to the gyroscopic effect of its rotary engine. When the Swedish Air Force (Flygvapnet) was established in 1926, the type was officially designated Ö 1 (Övningsplan 1, or Advanced Trainer 1). Remarkably, it served until the mid-1930s without any fatal accidents.
