Technical Specs

O.S Engines brushless motor for airplanes using a .40 - .50 size 2-stroke engine or 4-stroke .70 engine. Centrifugal fan design with angled ventilation holes draws air through the motor and across the windings and magnets for improved cooling.

Designed by O.S. engineers to be the new "gold standard" in electric power, these motors offer the same legendary quality and reliability that have made O.S. glow engines famous worldwide for 75 years. The motors are being produced in four sizes, equivalent to .25, .30, .40 and .50 size glow engines, with more choices coming soon.

Only O.S. brushless motors offer a ventilation system that increases efficiency and allows the motors to generate additional power. Key to this system is a unique centrifugal fan design. The fan draws air through specially angled ventilation holes, across the windings and over the magnets for greatly improved cooling.
O.S. 2-year Limited Warranty

Other performance features of O.S. brushless motors include:

A thick can design that resists distortion;
Three high-quality bearings;
Rigid and secure rear mounting design;
Shortened motor length for easy installation in short cowls;
A stainless steel prop shaft;
Supplied backplate, prop shaft, and gold-plated female plugs.
