The light airplane A-21 "SOLO" is designed for sporting and diverting flights, all-tours, patrol. Aircraft was designed within 7 months after 'old' public volunteer design bureau 'Aeropract' (established in 1974) became a commercial firm. Its' success proved that the new "Aeroprakt" is ready to compete on the market of light general aviation. As a result, KB obtained a certificate of designer and manufacturer.
