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 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.

Perfectly balanced power for today's truggies! With input from top truggy drivers, O.S. has developed the ideal engine for these hybrid hot rods! The 28XZ produces more low-end torque, providing the rpm/torque balance that heavier truggies require. The result is power that's incredibly smooth, for truggies more drivable than ever thought possible! Three needles enhance fine-tuning on the 21J slide-valve carb for optimal RPM at low to high throttle settings and enhanced response. Fuel for this engine is recommended to use 10~30% nitro.

Features:
• Three needles enhance fine-tuning on the 21J slide-valve carb
• The larger head aids in cooling, and is a 2-piece construction with inner head button
• The high-performance con rod features oilite bushings
• Includes a high-performance P3 hot turbo plug, 8 and 9mm carb restrictors and extra head shim
• Flywheel sets are required for certain truggy models
• 6 port piston sleeve for significantly increased power
