Cobra Motor 2814 2350KV Brushless

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 CP-2814 series motors are designed to power the the new class of FPV Racing Wing aircraft. They have a 5mm 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 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.

This motor has larger lead wires than the rest of the Cobra 2814 motors, and uses 4mm bullet connectors, to be able to handle the higher currents that the motor is capable of. Due to the high speed operation of this motor, it cannot be used with the regular Cobra DL-Series airplane speed controllers. Instead, we recommend that it be used with the Cobra Wing Series speed controllers, which use the BL-Heli firmware, and can keep up with the high speeds that these motors offer.
