Yak 55m 50-55cc Sport/3D ARF
click to enlarge
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
- Designed for all-out 3D performance!
- Lightweight, built-up construction with two-piece wing.
- Fiberglass cowl and wheel spats.
- Carbon-fiber tailwheel assembly.
- Uses popular 50 and 55 cc gasoline engines.
- 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.
