Cobra CP-2814-1050 Brushless Motor, Kv=1050

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.

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.

Included with every Cobra CP-2814 Series Motor is a complete accessory package which contains the following items:

● Heavy Duty 3mm Thick Cross Style Motor Mount
● Four M3x6mm Motor Mount Screws
● Bolt-On style threaded prop adapter with 4 screws
● Retaining Collar with Set Screw
● Three female 4mm bullet connectors
● Three pieces of heat-shrink tubing
