Recently Cobra Brushless Motors released a v2 version of the 2100kv, 2300kv, 2400kv and 2850kv CM motors. Some of our customers were inquiring about the new upgrades in these motors, so hopefully this covers these improvements!
The locking system for the magnets is created by having a machined lip on the inside surface of the flux ring the overlaps the back end of the magnets slightly. This captures the magnet and prevents it from sliding back and out of the motor. They have also started additional high-temperature industrial epoxy in between the magnets to prevent them from shifting side to side.
The following photos illustrate the difference. The first one is a side by side comparison of the rotor assemblies from a Cobra CM-2206-2400-V1 motor (on the left), and the new CM-2206-2400-V2 motor (on the right). As always, the blue material is epoxy putty that is used as balancing weight to dynamically balance the rotor assemblies to eliminate vibration when the motor is rotating at high speed.
Here is a close-up shot of the original V1 rotor housing. In this photo you can see the back edge of the magnets and the back edge of the rotor can. The magnets are securely attached to the inside surface of the rotor with epoxy glue:
Here is a close-up of the new V2 rotor housing. The back edge of the rotor can is about 50% thicker. This is because a lip has been machined onto the back edge of the rotor can that comes up and covers about 1/3 of the thickness of the magnet. This prevents the magnets from sliding back and coming out of the motor. You can also see the additional black epoxy that has been added in between and up the sides of the magnets to further lock them into place and prevent any shifting from side to side.
With these changes that have been made to the rotor assemblies, the only way to get the magnets to come loose would be to fly the quad straight into a brick wall.
The highly anticipated Cobra 2206 motors for extreme multirotor flight are now available for pre-order for our retail customers. These motors have an expected arrival date of early July 2015. We are fully expecting our first batch of these motors to sell out quickly. In order to ensure our valued customers get first dibs on them we’ve put up a pre-order form that is built into the motor’s respective pages along with all the specifications, motor performance graphs and propeller data.
Once you submit your pre-order request you will receive a confirmation email. Our Order Processor will be contacting you shortly before these motors ship to secure payment information and confirm shipping details. You may find all the information you need for each motor below:
Innov8tive Designs is proud to introduce our CEO’s new blog, “Lucien’s Corner”. When it comes to knowledge about multirotor flight, electrical power systems and overall understanding of R/C electronics, Lucien is pretty much the industry guru. He shares his tips, tricks, knowledge and information about all things that fly. Included in his blog are some videos of presentations and interviews, specific articles pertaining to the hobby and the ability to contact Lucien directly.

Since we offer motors, speed controllers, propellers and component parts that can be used in a multitude of different applications, questions may arise. What if you want to know what propeller goes best with what motor? Or can you run your heli on 3 or 4 cells? This is the benefit of our new Product Questions module. Built into every product we sell is a link to ask questions about that particular product that will be answered promptly by one of our technicians.
