A competition-training aerobatic aircraft, intended to rival the Extra 300, which was first flown in 1988. The originator and sponsor of the aircraft’s construction was Pawel Kwiecinski, a Polish-American — a doctor by profession, and a pilot and aviation enthusiast in his private life. The designers were Jerzy Smielkiewicz, Adam Kurbiel and Wieslaw Gebala. It was a mid-wing monoplane of entirely composite construction. It was first flown by Wieslaw Cena in 2001 with the registration marks SP-PAV.
It had unsatisfactory flight characteristics, so a radical redesign was decided upon — changing the configuration from a mid-wing to a low-wing monoplane. New wings were built, but the aircraft was never flown with them. The aircraft received the registration SP-YBV. After the death of Jerzy Smielkiewicz, no one was found to continue the project, which had been developed without success for 24 years. The aircraft ended up at Andrzej Papiorek’s Composite Structures Workshop in Jasienica, from where it was donated to the Polish Aviation Museum in Krakow by Pawel Kwiecinski in 2022.
