Description
Cobra Brushless Motors offer performance and value for Sport Flyers and Competition pilots alike. They are built from high quality components, and are designed to give years of top-level performance. All Cobra Motors are shipped in a custom designed package that features protective foam on all six sides of the box, with 3 separate compartments to protect the motor, accessory pack and cross mount.

The Cobra 3525 series motors have a 5.0mm shaft for extra strength, as well as oversize ball bearings to support the shaft and provide a long life. The internal bearing measures 11mm x 5mm x 5mm and the outer bearing measures a massive 16mm x 5mm x 5mm! The stators are made with 0.20mm lamination for maximum efficiency and minimum Eddy Current losses. Also included on the motor are ultra-flexible motor leads with high-temp silicone rubber insulation and 3.5mm bullet connectors already installed.




To complete the package, a complete hardware accessory kit is included with every Cobra Motor. Included in this hardware kit are the following items:

  • Heavy Duty 3mm Thick Cross Style Motor Mount
  • Four M3x6mm Motor Mount Screws
  • Bolt-On style threaded prop adapter with 3 screws
  • Retaining Collar with Set Screw
  • Three female 3.5mm bullet connectors
  • Three pieces of heat-shrink tubing
