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 4120 series motors have a 6.0mm shaft for extra strength, as well as oversize ball bearings to support the shaft and provide a long life. There are two internal bearing measure 12mm x 6mm x 4mm and the outer bearing measures a massive 17mm x 6mm x 6mm! The stators are made with 0.20mm laminations for maximum efficiency and minimum Eddy Current losses.
