Yak-55M

LARGE, LIGHT – AND UNLIMITED.


Five years after the Yak-55 took the Soviet team to #1 at the 1984 World Aerobatic Championship, the Yak-55M appeared — with a shorter wing and faster roll rate that challenged its rival Sukhoi SU-31. Those performance qualities carry over perfectly into this ARF...whose versatility shows that Great Planes knows exactly what you want in a 50cc aerobatic/3D model.Download a product flier

The Yak-55M’s high-quality, light balsa/ply construction can be seen by removing the large canopy hatch — which allows quick, easy access to your on-board electronics.  

The DLE™ Engines DLE-55cc shown here is a perfect partner for the Yak-55M, which accommodates many popular 50 and 55 cc gasoline power plants.

  Use a standard Pitts-style muffler, or take advantage of the built-in channel to install a canister or power-boosting tuned pipe. Great Planes leaves your options open, and includes the mounting materials for whatever exhaust system you select.

The two-piece, plug-in wing design makes it easy to transport the Yak-55M to the flying field in an average-size mini van or SUV. No trailer is needed, as larger gasoline-powered models often require.   Great Planes quality shines throughout this model’s almost ready-to-fly construction. Main assemblies are lightweight, built-up and MonoKote-covered. Except for the rudder, all control surfaces are factory-hinged. The cowl and landing gear spats are made of fiberglass, and IMAA-legal, Great Planes hardware is used throughout.   Its bold, multi-color MonoKote® trim suits the Yak-55M’s performance and helps you stay oriented during aggressive 3D flight. A molded replica radial engine adds exciting scale-like detail.

  The full-size Yak-55M is noted for offering extremely easy ground handling. The same is true of this sport-scale model, which includes a strong, lightweight, carbon fiber tailwheel assembly.

A century-plus of Yak performance.

     Born in Moscow in 1906, Alexander Yakovlev won a 200 ruble prize at age 18 for his first original design. He began his own company and won a design contest for fighter aircraft in the late 1930s, with what would eventually be known as the Yak-1.
     The Yak-9, the last of the wartime line, ranks among WWII’s finest fighters — Russia’s equivalent to the British Spitfire. The first postwar design, the Yak-18, also made history: It was the plane that taught the first man in space, cosmonaut Yuri Gagarin, how to fly.
     By the time the Yak-50 emerged in the mid-1970s, it was a much different aircraft than the 18 — with more power and a smaller, lighter airframe. It also claimed five of the top ten positions in a 1976 world contest, competing with Zlin 50s and Pitts Specials.
     The design was later given to Russia’s leading light aircraft designer, Slava Kondratiev, resulting in the Yak-55 — described by Russian aircraft authority Richard Goode as giving “85% of a Sukhoi’s performance at 40% of the cost.” The Russian Aerobatic Team first used the Yak-55 in 1984 and immediately won the World Aerobatic Championship.
     By the mid-1980s, Sukhoi had introduced the all-composite SU-26. To remain competitive, the Yak-55’s wingspan was reduced, and it became the Yak-55M...capable of a faster roll rate, though with a loss of height due to increased induced drag.
