These are the RS2205 2300Kv Race Spec Cooling series motors from Emax that give you the highest performance for FPV racing. These motors have been redesigned and engineered to perform better than most other in their class, with every motor precision-crafted. When these motors are paired with performance-driven propellers, you will experience thrust like never before!

If you are looking for the RS2205 motor to use on a smaller quadcopter with 4 inch propellers check out the RS2205 2600Kv

Note: we now sell the new RS2205 S motors from Emax - check them out to see the improvements. 

What’s so Cooling about these motors?

Unique fins have been engineered into the bell to draw up cool air from the motor base and through the coils as the motor spins. The faster the motor spins, the more air is pulled through and so the motor remains cool. This procedure reduces the heat soak by at least 30% and gives the motor a longer lifespan.
