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 2221 series motors have a 0.157 inch (4.00mm) shaft for extra strength, as well as oversize ball bearings to support the shaft and provide a long life. The stators are made with 0.20mm laminations 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.
