Introducing the Emax Race Spec family of high performance brushless motors for multirotor FPV racing. Designed and engineered to perform better than most in it’s class, every motor is precision crafted within tight tolerances. Paired with performance driven props from any leading manufacturer will result in unreal thrust.

Featuring unique fins machined into the bell draw up cool air from the motor base and through the coils as the motor spools up. The faster it spins, the more air it ventilates. These cooling fins can reduce heat soaking by up to 30% depending on your environment. This “cool” feature allows the RS2205 to not only have a longer lasting motor, but also harness the power of N52 magnets.

N52 Magnets are arguable the highest grade magnets available to date. These magnets provide improved acceleration, stopping power, and sustained RPMs during high kv. Additionally each EMax motors is built with genuine Japanese NMB Bearings provide long lasting, smooth performance.

EMAX RS2205 2300kV Brushless Motor (CCW Rotation/CW Thread)
One of the best motors I have ever used. Super fast smooth and strong. I have several builds with them that have also been flown in garages and still run great. Highly recommended. Also note that CCW rotation only means the markings on the motor show this rotation. The motor can spin in any direction as needed. The CW thread is for a standard threaded M5 nut. Also includes 3x prop nuts that are serrated for extra bite on the prop. I use all the same thread to limit the need to carry different types of spares.
