The completely redesigned Emax RS2205-S has received major upgrades with features racing multirotors absolutely need. The new S type motor is lighter, yields faster bell rotational response, higher thrust, uses premium materials and backed with EMAX's legendary production quality and great reputation already established.
Lighter and Lower Profile:
2 grams lighter than the first version of the RS2205, the RS2205-S has been overhauled for the weight conscious racer where literally every gram saved is a bonus. The bell has been redesigned to have a lower profile without sacrificing the structural integrity of the motor. This eliminates unnecessary mass and allows quicker rotational response of the bell. The shorter motor height allows a lower center of gravity closer to the mounting point.
Emax RS2205-S cooling fins have been reworked to keep the motor height and weight low while maintaining functionality and still keeping a cool running motor even under intense race conditions.
N52SH Curved Magnets:
By utilizing N52SH curved magnets, the pulling force between the stator and magnet is greatly increased. The design of the motor extracts every bit of force from these magnets and keeps it constant throughout the phases.
Genuine Japanese NMB bearings ensure smooth, long-lasting performance.
Compared to the RS2205, the new RS225-S cranks out another +100g of thrust. Paired with a KingKong 6x4 propeller, expect over 1,400 grams of thrust (Check out the full motor results: http://www.miniquadtestbench.com/emax-rs2205s-2300kv.html).
Hollowed Steel Prop shaft and main shaft:
The upgraded shafts maximize durability. No worry of damaging threads during crashes.
Bell Retaining Screw:
No more E-Clips. With a retaining screw, RS2205-S has no chance of having bells pop out during a race. It is also easy to service the motor without needing a special tool.
EMAX Legendary Production Quality:
Engineered and produced In-House with state-of-the-art production techniques and machines, every motor that comes out of our factory is guaranteed to have the tightest build tolerances. It is with this ability, that we can achieve 0.10mm magnet to stator air-gap and crash-durability racers come to love, The Emax Red Bottom Motors have yet again proven why they are so popular amoung the Drone Racing Pilots all over the world .

The previous version of the RS2205 were a really good quality and reliable motor but I'm loving the new S type they seem really powerful and yet smaller and more powerful than the earlier version. Fast delivery and great service too .
