OS OMA-5020-490 50MM BRUSHLESS MOTOR (490 RPV) EQUIV .40-.50 SIZE 51013000
Pilots loyal to outstanding O.S. performance but eager to fly electric now have the ideal option — powering electric airplanes using new O.S. brushless motors!
Designed by O.S. engineers to be the "gold standard" in electric power, these motors offer the same legendary quality and reliability that have O.S. glow engines famous worldwide for 75 years.
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.
Other performance features of O.S. brushless motors include:
- A thick can design that resists distortion
- 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 these brushless motors, O.S. reaffirms its standing as R/C's most innovative and respected resource for all model power needs. In the future look for more sizes and choices for car, helicopter and ducted fan modelers!
