Cobra C-2826-EF1-SS Brushless Motor, Kv=1200
Cobra C-2826-EF1-SS Brushless Motor, Kv=1200
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 2826 series motors 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.
The Cobra C-2826-EF1 motor was developed for Electric Pylon Racing, and has been accepted as a certified motor by the EF1 Competition racing committee. This specific model has a stock motor shaft in it that sticks out the back of the motor for pilots that want to reverse mount the motor and use a collet style prop adapter or spinner. This also allows you to mount the motor in a pusher configuration on an FPV Racing Wing type aircraft.
The Kv value of this motor is optimized for use with an APC 8x8-E prop running on a 4-cell Li-Po battery pack, as stated in the EF1 Racing Rules.
Included with every Cobra 2826 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
● Three female 3.5mm bullet connectors
● Three pieces of heat-shrink tubing
