Yak 18A

The predecessor to the Yak-52 and built in great quantities, although sadly, under the Soviet system virtually all the aircraft have been melted down!  This should not be confused with the Chinese CJ6, which was based on the 18A but most feel that the 18A was a far superior aircraft.  It has fully retracting undercarriage; the economy of 260hp but with fully inverted systems.  A real collectors aircraft today and sure to appreciate.
