OS ENGINES OMA-5025-375 High Performance Brushless Motor (M8,100A)

High-Powered Brushless Aircraft Motors from O.S.!

Pilots loyal to outstanding O.S. performance but eager to fly electric will now have the ideal option — powering electric airplanes using new O.S. Brushless Motors!

The OS OMA-5025-375 High Performance Brushless Motor is designed equivalent for 4-stroke 91 or 2-stroke 50 size airplanes.

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. Initially, the motors are being produced in 6 sizes, equivalent to .10,.15,.25, .30, .40 and .50 size glow engines.

Only O.S. brushless motors will 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.

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
With the introduction of these brushless motors, O.S. reaffirms its standing as R/C's most innovative and respected resource for all model power needs. O.S. plans to expand its motor lineup in the near future with more sizes and choices for car, helicopter and ducted fan modelers.
