Description Cobra CM-2204-32 2-4S 1960Kv COBRA 2204 brushless motor, all parts are made of a high-precision CNC machining centers, all of the surface oxidation treatment. In pursuit of the perfect groove full rate, we use high-temperature and high-purity oxygen-free copper wire wrapped by hand, as well as high-grade magnet 0.2 mm laminated to improve efficiency. These materials reflect the value of the Cobra motor. 2204 motor weighs only 22.5 grams, and the bases loaded with cross one, is designed specifically for ultralight indoor acrobatic model (F3P) design. Two large and high-quality ball bearings fixed rotor to ensure its long life and good balance. Propeller motor with a full installation accessories, as well as to protect the motor and its accessories, perfect packaging.

The prop chart data contained in the measure is based on a controlled test environment actually taken. Test voltage used is based on an appropriately sized lithium polymer battery current consumption of the motor being tested. If you are using a large capacity battery than normal, or a very high C- rated battery, the actual voltage will be higher than shown in this figure, which will lead to Hagrid current consumption for each use of props. You should always test your power system with Watt meter, every time a prop is used to ensure you do not exceed the recommended motor rating is used. This figure props proposal is received on the entire operation of the motor based on sufficient cooling. If the inner cover is a motor used, you must provide sufficient cooling to the motor to ensure that operation is not getting too hot.
