Emax RS2205 2600kv Motor Review

  • Emax RS2205 2600kv Motor
  • Emax RS2205 Motor Packaging

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.

1x Emax RS2205 2600kv Motor (CW or CCW Available)
3x M5 Nylock Prop Nuts
