Introducing the Emax Race Spec series of high performance brushless motors built for multirotor FPV racing!
From the drawing board through to the production line, these motors have been designed and engineered to provide premium performance in their class. Every motor is precision crafted within tight tolerances and paired with high performance props from any leading manufacturer they will deliver awesome thrust and speed to burn.
Emax have produced an excellent motor and gone the whole nine yards by incorporating some real quality features.
The unique cooling fins draw up air from the motor base that then passes through the coils as the motor spools up. The faster it spins, the more air it moves. This “cool” feature reduces operating temperatures by up to 30% providing you with a longer lasting motor.
This series of motors uses the highest grade N52 magnets allowing motor operation that provides outstanding acceleration, stopping power and sustained high RPMs and this is assisted by genuine Japanese NMB bearings that ensure the smoothest operation.
Emax Race Spec motors will deliver reliable and outstanding performance for your racing quad and you know that's exactly what you need if you want to take that chequered flag.

bought 4 of these motors and 3 of them rattle like crazy after one 4 minute flight. Still waiting for initial review of my claim, but beware and watch out! There might be a bad batch out there.
I have them running with Kiss FC and 24A Kiss ESCs, Diatone Tyrant 215 frame and 1300 Graphene batteryThis motor definitely continues the insane trend started by the 2300kv RS2205. I've never seen performance like this out of a motor in this class. It has set the standard for high KV motors that will be hard to catch. The combination of stator size, strong magnets and tight tolerances create an RPM efficiency that surpasses motors with significantly higher KV.
