Cobra Brushless Multirotor Motors offer performance and value for Your RC Models. 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 sides, with separate compartments to protect the motor and accessory pack.
The Cobra CM-2820 series motors have a 5.0mm motor shaft for extra strength, as well as oversize ball bearings to support the shaft and provide a long life. The stators are made with 0.20mm laminations for maximum efficiency and minimum Eddy Current losses. Since these motors are typically soldered directly to the speed controller for reliability, the 2820 motors come without bullet connectors and feature extended pre-tinned motor leads that are 17 inches (430mm) long. These motors also have 3mm threaded holes in a 25x25mm pattern on the back plate for easy installation on your model.
The CM-2820 series motors include mounting options for both flat carbon fiber props and conventional style props. The top of the motor has a 4mm centering pin and four M3x0.5mm threaded holes on a 12mm mounting circle. Also included is a bolt-on style prop adapter that features an M6x1.0mm thread, along with a prop washer and nylon insert prop nut to provide solid attachment for standard style propellers that will not loosen up and slip during use.
Included with every Cobra CM-2820 Series Motor is a complete accessory package which contains the following items:
Four M3x5mm Socket Head Screws
Four M3x6mm Phillips Head Screws
Two M3x8mm Socket Head Screws
Machined Aluminum Top Plate for Carbon Fiber Props
Machined Aluminum Prop Adapter
Machined Aluminum Prop Washer
Locking Prop Nut with Nylon Insert
