This is the Savox BSM2940, 3500kV Brushless Outrunner Motor, and is intended for use with 450 class helicopters. The Savox BSM2940 450 class brushless outrunner motor keeps your RC helicopter flying high while cooling itself down. The machined aluminum housing with 6 angled cooling ports and an internal cooling fan allow Savox out runner motors to pump air through the motor, giving you a 10% drop in temperature over other popular brands. Agile and fast, Savox brushless motors facilitate sharp moves in your flying experience.


  • Unique cooling system design patented by Savox.
  • Precision wound with machine accuracy.
  • Durable black Electro-Coat finish on the flux ring.
  • High-tech laser etched logos and item numbers to better maintain balance of the motor. No stickers or decals throwing off your tick-tock!
  • Top quality stator plates are epoxy coated on the inner surface to prevent winding shorts. The stator plates are .020mm in diameter.
  • Premium shielded ball bearings are used to support the shaft in all motors.
