The Yakovlev design number 50, or the Yak-50, is a
single-place, low wing, single engine, competition-level
aerobatic aircraft designed by the Yakovlev Design Bureau
in Russia in 1972.
The first flight was in 1972. It was put to the test in
the 1976 World Aerobatic Championships, in which it took
the top two places in the men's competition and the top
five in the women's.
Although it was never introduced directly into Russian
military service, military pilots who were trained in
state-sponsored aeroclubs (DOSAAF) were trained in the
Yak-50. The Yak-50, having a much better weight to
horsepower ratio than the standard trainers of the day
(Yak-18A), was used as an advanced aerobatic mount for
competition and military fighter pilots. The Yak-50 was
used as a military trainer in several other nations. It
has a better climb capability than many World War II
aircraft, including the P-51 Mustang and the Spitfire.
