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 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 laminations for maximum efficiency and minimum Eddy Current losses.
