This is the O.S. .40, 490kV Brushless Motor. 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. 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. Pilots loyal to outstanding O.S. performance but eager to fly electric will soon have the ideal option powering electric airplanes using new O.S. brushless motors!

O.S. brushless motors feature a ventilation system that increases efficiency and allows the motors to generate additional power. The 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:

  • Recommended for 4-stroke 70 size, or 2 stroke 40-50 size airplanes
  • 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 back plate, prop shaft, and gold-plated female plugs

Specifications:
Rotor Diameter: 50mm
Magnet Length: 20mm
Output: 490kV
Watts: 1110
Weight: 350g (12.3oz)
