About the Yakovlev Yak-55

The Yakovlev Yak-55 is a single-seat aerobatic competition aircraft designed in the Soviet Union during the early 1980s specifically for unlimited-category aerobatic competition. Developed by the Yakovlev Design Bureau under the leadership of Sergei Yakovlev, the type first flew in 1981 and quickly became the mount of choice for Soviet aerobatic teams competing internationally. Its mid-wing monoplane configuration, symmetrical airfoil, and powerful 360-horsepower Vedeneyev M-14P nine-cylinder radial engine give it exceptional roll rates exceeding 400 degrees per second and the ability to sustain inverted flight indefinitely—capabilities that made it a formidable competitor against Western types like the Extra 300 and Pitts S-2.

The Yak-55's design prioritizes g-tolerance and control authority over speed or range. With a limit load factor of +7/-5g (ultimate +12/-9g) and full aerobatic capability across its entire speed envelope from 68 knots to its never-exceed speed of 270 knots, the aircraft can execute the most demanding figures in the Aresti catalog. The cockpit is positioned well forward to optimize visibility during vertical maneuvers, and the control system uses push-pull rods rather than cables to eliminate slop during rapid reversals. The later Yak-55M variant, introduced in 1989, featured a slightly longer fuselage and refined aerodynamics that improved spin characteristics and became the standard export model.

Though production ended in the 1990s following the dissolution of the Soviet Union, the Yak-55 remains active on the international aerobatic circuit and in private hands, prized for its robust construction, relatively low operating costs compared to composite Western competitors, and forgiving handling that makes it suitable for pilots transitioning into unlimited aerobatics. SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
