Brand Overview

The OS Engine Brand covers one of the oldest and most established Internal Combustion product lines in the RC market place today.  Dating back to 1936 with its 1.6 cc O.S. Type-1 miniature gasoline engine, the line has evolved over the decades through the fires of international competition.

Over the years the OS Engine brand has pioneered 2-stroke engine design, 4-stroke engine technology, multi-cylinder engine research (including V-arrangement,  Radial configuration, and horizontally opposed configurations),  and the rare but intriguing Wankel Rotary configuration.

Today's product line-up fills the power needs for anything from RC helis, RC aircraft, RC boats, and RC cars.

From the Brand's website, they introduce themselves as follows:

First to introduce a mass-produced 4-stroke engine, an innovator in every phase of R/C engine production, O.S. also retains a tradition of craftsmanship that pays off in durability and power. Each new engine is the product of over two years of testing and design—and more than two generations of R/C engine experience.

Today, the OS Engine brand products still be found in the thick of things at almost any RC heli, aircraft, car, or marine competition.  Their products and parts can readily be purchased at local hobby shops and online retailers world-wide.
