O.S. GT22 Gas Engine

Description

In 1936, Shigeo Ogawa set up his original machine-shop, making model steam engines. At the same time the first 1.6 cc O.S. Type-1 miniature gasoline engine was made. 200 production models sold under the name “Pixie” were exported. A short time later the O.S. brand came about. For all these years, OS Engines have been a recognizable name of power, reliability, cutting edge design and quality in the model engine arena. From their much loved “Max” series, to their unique Wankel rotary engine, to the powerful O.S. Speed series engines, they have something for everyone. HobbyKing is proud to be able to bring a wide selection of the latest O.S. Engines to you.

An investment in O.S. gasoline power quickly pays for itself in fast starts, higher power and more flights from your fuel budget. For the many planes that use 2-stroke .91 or 4-stroke 1.20 glow engines, the GT22 — the third gasoline engine available from O.S. — is the perfect choice. It cranks out nearly 10% more power than other 2-stroke gasoline engines of similar size! Throughout the GT22, the fit and finish are outstanding — always delivering the same high performance as when you first installed your brand new, hand-crafted, quality inspected O.S. engine.

 A special roller bearing on the lower end of the connecting rod allows you to run 50:1 fuel/oil mixture, which is very clean running compared to messy nitro fuel. Balanced, optimized crankshaft for vibration control and improved performance. Twin ball bearings support the hardened steel cranksft for the ultimate in efficiency. Fuel for this engine is recommended to use 87 octane and a quality 2-stroke oil, mixed at 50 parts fuel, to 1 part oil.

Features:
• Uses beam mounting, unlike most other gasoline engines, for easy installation in planes designed for glow power
• Pitts style muffler has been reinforced at seams, bends and mounting bolt locations for maximum strength
• Redesigned for even easier starting, the IG-02 electronic ignition system handles 4-6 cell NiCd/NiMH or 2-cell LiPo/LiFe batteries
• Rear-mounted Walbro carburetor is custom-designed for the GT22 — a choke rod guide has also been integrated into the crankcase for effortless setup
