Design and development

Design originally began in 1993 as a development of the Sukhoi Su-29 aerobatic aircraft.[1][2] Development was suspended due to economic problems, and when restarted in 1998, the aircraft was redesigned, reducing the aircraft's size and replacing the originally planned M-14 radial engine with a LOM Praha 337S inline engine.[1][3] The first prototype made its maiden flight on 27 July 2001, with a second flying by June 2002.[1] As no users have yet expressed interest in the aircraft, the project is currently proceeding at a low pace.
