Introducing the Emax Race Spec family of high performance brushless motors for multirotor FPV racing. Redesigned 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.

The 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. Cooling fins significantly reduce heat soak by at least 30%. This “cool” feature allows the RS2205 to not only have a longer lasting motor, but also harness the power of N52 magnets.

N52 Magnets:
Uses the highest grade magnets. Better acceleration, stopping power, and sustained RPMs during high kv.

Genuine Japanese NMB Bearings provide long lasting, smooth performance.

  1. you get what you pay for review by Robert on 6/27/2017

    2 out of 5 had noisy bearings right out of box

  2. Powerful, good looking and cheap review by Bob on 12/13/2016

    After being having a frustrating experience with my cobra motors I have been rocking for a year (whent through 3 of them because the shafts bend like nothing), the magnets finally started giving away, making it a good reason to upgrade. These motors are packages very well, very good quality for the money. The red bottoms look great with my red exopro, props, pdb and hardware of my RR5. These also are noticeably cooler at the end of each flight with a standard 5x4x3 HQ prop. Very happy! Oh and they seem to be pretty durable too.

  3. great Value review by Matthew on 12/5/2016

    I've been flying these for over 6 months now... Super durable I've yet to break one of these... very smooth flying and good thrust.

  4. Great power review by John on 11/26/2016

    Amazing thrust on my 210 with only a 3s. Very impressed

  5. 10/10 review by Aaron on 11/25/2016

    this is the lowest i have seen these motors! the fact that they can have over 1k of thrust each is crazy. all my builds now will have these motors.

  6. Great motors review by Steven on 11/23/2016

    These motors are great. They are vvvveveeeeerrrry efficient. They handled quad blades without any problems. The only con is the paint scratches easily.

  7. Red power. SWEET review by Fred on 10/9/2016

    luv these things. So durable. Where my cobra motors would swell and melt wires these things just power out and go, go, go! Run cool too!

  8. Dope beyond dope review by Matt on 5/30/2016

    These motors are awesome, highly recommend them. Just added them to my Vortex 250 Pro, which was already fast, and they took it to the next level, well that and some new quad-blade DAL props. Power baby, power!!

  9. Great little motor review by Christopher on 4/20/2016

    Great motor. Silk smooth, and nice gauge wire on the coils.
    They gives you 3 lock nuts with each motor too.
