Cobra CM-2208-20 2-4S 2000Kv New Version
Cobra Brushless Multirotor Motors offer performance and value for Your quad racers. 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-2208 series motors have a 3.0mm 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 to save weight, the 2208 motors come without bullet connectors and feature extended pre-tinned motor leads that are 10 inches (254mm) long. These motors also have 3mm threaded holes in a 16x19mm pattern on the back plate for easy installation on your model.
The CM-2208 series motors feature an integrated 5mm threaded motor shaft which eliminates the chance of having a prop adapter spin off in flight. The included prop washer and nylon insert prop nut provides a solid attachment for your propellers that will not loosen up and slip during use.
Included with every Cobra CM-2208 Series Motor is a complete accessory package which contains the following items as picture shows above.
Four M3x5mm Motor Mount Screws
Four M3 Flat Washers
Machined Aluminum Prop Washer
Locking Prop Nut with Nylon Insert

You need power for your mini racing quads? You need Cobra cm-2208-20 Motors!
The data contained in this prop chart is based on actual measurements taken in a controlled test environment. The test voltages used are based on a properly sized Li-Po battery for the current draw of the motor being tested. If you are using a larger than normal capacity battery, or a very high C-Rated battery, your actual voltages will be higher than those shown in this chart, and this will result in higer current draw for each prop used. You should always test your power system with a watt meter whenever a prop is used to ensure that you are not exceeding the recommended rating of the motor being used. The prop recommendations in this chart are based on the motor receiving adequate cooling throughout its operation. If your motor is being used inside a cowl, you must provide adequate cooling to the motor and make sure that the motor is not getting too hot during operation.
