The Aircraft
The Yak-52 is a two seater tandem aircraft designed in Russia by the Yakovlev Bureau.  The aircraft production started in 1979 in Romania (Aerostar).  Since then over 1,800 machines have been produced.  The Yak-52 was used in the Soviet Union as a basic military trainer as well as primary and advanced aerobatic trainer.  Thousands of Russian Air Force pilots went through training with DOSAAF (Air Cadets equivalent).  The Yak is all-metal, fully aerobatic machine with an inverted fuel system.  As an aircraft with excellent performance and remarkable strength (G limits +7/-5 with two pilots and full fuel) the Yak-52 enables training from basic to unlimited level.
