O.S. Max 55AX Two Stroke Glow 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.

Add some power and spunk to your "40 size" nitro plane with the O.S. 55AX. It features the same bolt pattern as the 46AX though boasts greater horsepower! The 61A carburetor has an angled back needle valve which keeps your fingers much further away from a spinning propeller. Twin ball bearings support the hardened steel crankshaft for the ultimate in efficiency. Includes new 4040 Power Box™ muffler which increases volume for greater power, while at the same time being very compact. Angular head design looks great and significantly increases surface area for better cooling. This ABL (Advance Bimetallic Liner) sleeved engine will provide years of power and reliability. Fuel for this engine is recommended to use 5~20% nitro, with at least 18% oil content.
