After learning the shortcomings of the Yak-18P in the role of competition aerobatic plane, A.S.Yakovlev rolled out new sport plane in 1965. Externally it differed from the predecessor by cockpit moved back and smaller wing dihedral (2° vs 7°), but inside the Yak-18PM housed new 300hp engine.

Improved take-off and landing characteristics Yak-18PM allowed to replace center section flap by airbrake with 80° travel. Ailerons and tail controls had improved trim system. Fuselage, wing and tail structure was strengthened, allowing maneuvers load in range -6+9g.

At the 1966 World Championships at Moscow the USSR team swept the competition outright, flying the Yak-18PM's. This became the first, but not the last victory of Soviet team, flying Yakovlev aerobatic planes.
