Yak-18A Max, 1956

This very popular trainer was the predecessor of Yak-52. Following the Yak-18U in the prolific Yak-18 series, it introduced a reinforced all-metal tubular structure, a more powerful engine with now-famous radial cowling and confirmed the Yakovlev's choice of tricycle gear for initial training aircraft. Of 927 built at Arseniev plant in 1957 - 1961, few remain, mainly in private hands. A different version was produced in China, under the name of CJ6A Nanchung, of which 1796 were built.
