If memory serves, the Czech air force used the S-99 to start with, which was basically a 109 copy. The 199 came about due to a shortage of DB-605 engines, so they modified the remaining uncompleted airframes w/ the Junkers Jumo used on the HE-111.These were then sold to the Israeli air force, who were desperate for aircraft. The 199's flight characteristics (particularly on takeoff and landing) were total crap, because the Jumo engine had more torque than the DB-605, which was exacerbated by the fact that the landing gear had to be modified as well to fit the engine. They were placed farther back and were vertical, which resulted in a lot of flips.
