Giving an impression of just how much is on show in the famous Kbely museum, this view shows a trainer version of the S-199, a Czech post-war reworking of the Messerschmitt Bf-109G design. With a shortage of Daimler-Benz engines, Avia substituted the Junkers Jumo power plant. Performance was much less satisfactory however and difficult handling characteristics led to the 600 or so of the S/CS-199 series built being generally disliked, many being written off in accidents.
