It is a amazing that this aircraft came out to be such an exceptional and light weight aircraft as it was. The design team consisted of a handful of experienced Engineers, but most of the designers and drafters came from other industries, such as Farming equipment, Sewing machines and Weapon manufacturers. The very rigid system of weight management was indeed essential for the success of the program. Designers of Farm equipment didn't have any understanding of weight savings, and from a manufacturing point of view they had to learn how to keep tight tolerances, which initially was a big problem. Later on this served to establish a foundation of subcontractors for the future of the Swedish Aerospace industry.

The end result was a small, light weight, fast and agile fighter which was up to par with the best fighters which were available in 1943. Although underpowered, due to the low drag it was extremely fast. It did not have any good altitude performance, but for the defense of the Motherland and being such a Stop-Gap project as it was, it still performed it's duty to the fullest.
