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.

To serve the needs for larger size models, Cobra has introduced the new 53mm Motor Series. The Cobra 5320 motors have an 8.0mm shaft for extra strength, as well as oversize ball bearings to support the shaft and provide a long life. There are two internal bearing which measure 16mm OD x 8mm ID x 5mm thick and the outer bearing measures a massive 22mm x 8mm x 7mm! The stators are made with 0.20mm laminations for maximum efficiency and minimum Eddy Current losses. Also included on the motor are ultra-flexible 12 AWG motor leads with high-temp silicone rubber insulation with the ends stripped and pre-tinned, ready to solder on the connector of your choosing.
