Details

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-2204 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 2204 motors come without bullet connectors and feature extended pre-tinned motor leads that are 4-1/2 inches (110mm) long. These motors also have 3mm threaded holes in a 16x19mm pattern on the back plate for easy installation on your model.

The newest version of the CM-2204 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-2204 Series Motor is a complete accessory package which contains the following items:

  • Four M3x5mm Motor Mount Screws
  • Four M3 Flat Washers
  • Machined Aluminum Prop Washer
  • Locking Prop Nut with Nylon Insert

    I had a motor burn on my RTF rig and decided to fix it instead of wait for warranty work to be approved. Chose this motor based on prior reviews...glad I did!

    The motor is premium quality with solid wiring and components.

    I have converted my ImmerssionRC Vortex 285 from T-Motor 1806 to Cobra 2204 and from a 3s to 4s with 6040 props. It is superfast and much more durable as compared to Multi elite 2204 where 2 prop stem broke from minor crashes. Can get Mount Adapter to convert from 1806 to 2204 online.

    MUCH better than the dys 1806's I upgraded from. Running on 5x4x3 HQ props, RG20's, 4s these really pack a punch.
    I have bent a shaft though. The inner magnets (stator) are so close to the bell magnets that even the slightest bend, the motor is unusable. Great for efficiency, not durability.

    Excellent motors, I bought 2 sets and would not hesitate to buy again whenever they are in stock. I use them at 4s. They are much audibly noisier than equivalent Tiger or EMAX motors, but that does not seem to affect the flight characteristics. With a 30fps camera such as a Mobius I noticed they are a bit more vibey than Tiger motors (was seeing a bit more jello with exactly the same props+ESCs). At 60fps this is NOT an issue, there is zero jello.
