Emax RS2205 2300kv Motor Review
Emax has typically been known for good value for money in the budget side of miniquads and also for their OEM motors for larger companies such as DJI but most people do not say the Emax name when they are talking about high performance motors…. Well bite your tongue because that has all changed… Like in the Matrix I believe Emax has decided to take the red pill and see how far the rabbit hole will go with their new line of high performance Emax RS2205 2300kv motors.
The Emax RS Series also referred to as the “red bottom motors” rewrote the book in terms of power and performance for miniquad motors and easily bested the king of the hill Cobra 2204 2300kv (its really a 2205 marketed as a 2204) by a fair margin and raising the bar for the rest of the companies developing miniquad motors. Even the MT2205II series 2300kv motors (baby brother to the RS series) are able to easily out perform the Cobra motors by a good margin. Not only are they more powerful, but they also handle the power much better due to the exceptional cooling that is provided by their active cooling design of the bell housing and motor mount that significantly reduces the temperatures of the motor and winding’s thus allowing for higher power output without heat soaking the motor and burning the winding’s. This better cooling allows for smaller wire and and triple wire winding’s with stronger high grade N52 Neodymium magnets to provide more motor force to keep the props spinning at the proper RPM and genuine Japanese NMB Bearings.

Emax has also put a lot of thought into the packaging and what is included with the motors. They come in a very nice plastic box (perfect to store a Mobius or Runcam in) that is lined with foam padding with cutouts for all the goodies.. It also comes with three M5 Nylock nuts instead of the typical one nut that most companies provide and as we all know its going to be the CCW one that you loose and can not run down to Home Depot and buy. It also comes with two sets of motor screws for different thickness arms and last but not least a M3 hex wrench. its this forethought and attention to detail that really caught my eye when I opened up these boxes.

As you can see in the results the Emax RS2205 2300kv Motor has exceptional performance across the board and manages to pull a staggering 1300 grams of thrust with a King Kong 6040 prop on 4S. These are thrust results we have never seen out of a 2204/2205 sized motor and have been only achievable by running the battery hungry 2208 sized motors and aggressively pitched 6045 and larger props. So Emax has truly pulled the white rabbit out of its hat and came up with some new tricks that have the other motor manufactures playing catch up..

Emax has really rewritten the book on miniquad motor performance with the RS2205 series and thus we give it a excellent review based on power, performance, packaging and overall build quality
