Design and development
Edward Margański, Jerzy Cisowski and Jerzy Makula developed the Swift at Bielsko-Biała from the SZD-21-2b Kobuz 3.[1][2] The prototype first flew in 1991.
The glider is made of glass-fibre epoxy composite. It is very strong (stressed for plus and minus 10g) and manoeuvrable (a roll takes 4 seconds). Larger tips are available to increase the span to 15m. It has a retractable undercarriage.
