The Yak-52 was designed by the Yakovlev Design Bureau of Moscow, Russia, in the old USSR.
All Yak-52’s--more than 2000--have been built by Aerostar of Bacau, Romania.
Great value for the money -- they have increasingly become popular with Western pilots in the last decade. We see them a lot in airshows out here. Fine shot of this one with the support people around -- gives good proportions clues!
