O.S. Speed 19XZ-B 1/8th Scale Buggy Two Stroke Nitro Engine

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 OS 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 OS Engines to you.

Ever wanted one or two less pit stops during a main to extend your lead over your competitor? The O.S. 19XZ-B Speed offers 10% better fuel economy over the current 21XZ-B Speed with the 21J2 carburetor and 6mm carburetor reducer and still has all the performance you need to win. Finesse and fuel economy for tight, twisty 1/8 scale tracks!

The 19XZ-B Speed also incorporates a DLC (Diamond Like Carbon) coating crankshaft to reduce friction and improve wear life and durability and also prevent corrosion. The crankshafts passageway is silicone filled to direct the air smoothly into the tuned cylinder assembly and crankcase. Fuel for this engine is recommended to use 10~30% nitro.

Features:
• Ceramic bearings reduce rolling resistance throughout the power performance
• A square bore/stroke (1:1) short stroke provides stress free performance and sharp acceleration

• Balanced, optimized crankshaft for vibration control and improved performance
• Black anodized crankcase with fins helps direct air flow over crucial parts of the engine and helps dissipate heat to keep it cooler
