The Cobra Champion series motors are the most powerful versions ever made for FPV Racing! A completely new design that increases cooling and efficiency, these motors provide the ultimate power for your FPV Racing Quads. 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 CP-2205 motors come without bullet connectors ,and feature extended pre-tinned motor leads that are 2-1/4 inches (55mm) long. These motors also have 3mm threaded holes in a 16x19mm pattern on the back plate for easy installation on your model.

The CP-2205 series motors feature an integrated 5mm threaded motor shaft which eliminates the chance of having a prop adapter spin off in flight. The included nylon insert prop nut, which has an integrated prop washer, provides a solid attachment for your propellers that will not loosen up and slip during use.

Also included with every Cobra CP-2205 Series Motor is a complete accessory pack, which includes everything you need to securely mount the motor to your quad frame, and to mount the prop to the motor.

The hardware kit contains the following items:

● Four M3x6mm Socket Head Motor Mount Screws
● Four M3 Flat Washers
● One Machined Aluminum Prop Washer
● One Locking Prop Nut with Nylon Insert

Performance Graph Instructions

This downloadable PDF file shows the step by step process to use for interpreting the data shown in the Motor Performance Graphs. By following this procedure, you can determine how to select a proper motor for a Multirotor aircraft, as well as calculate required power levels, determine overall prop efficiency and calculate expected flight times based on the battery size that is used. This document can be printed out and saved as a valuable reference tool to keep in your workshop for future use as well.

Motor Performance Graph Instructions

*Please observe the motor specifications properly. This will determine the correct size ESC required for proper operation*
*Motors do not come with replacement parts!*
*Motors that have failed\burned running on an incorrect ESC size will void warranty*

Product Questions

Sort by ASC
Read through the question about the screw length but have a little more to add in the form of my own question. How much room is there between the backplate and the windings? I have a set of motors that are still flying great but each one has at least 1 or 2 stripped out mounting holes. And further more I switched to a 4mm frame. Its only a couple threads in each hole stripped, so I can get away with a little bit longer screw as long as there's enough room between the back plate and windings.
Would you recommend these motors with 4S 1300 75c batteries using 5040X3 Dal Indestructible V2 props? I am using the TBS Powercube for FC and ESC's. Thanks!
Hi,can this motors handle 5s lipos with 5045x3 props??.
Is the motor good balanced inside ?
What aluminum alloy are these motors manufactured with?
Are the mounting screws that are included with the motors sized (length) for 3mm or 4mm thick multirotor arms?
