The completely redesigned RS2205-S is upgraded with features racing multirotors absolutely need. The motor is lighter, yields faster bell rotational response, higher thrust, uses premium materials and backed with EMAX's legendary production quality. 

* Note: This motor has CW threads on the propeller shaft. There is no CCW version of this motor. (CCW really isn't needed). 

• Lighter and Lower Profile
  2 grams lighter than the first version of the RS2205, the RS2205-S is a 2205 motor which has been overhauled for the weight conscious racer. 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. 
  
  
• Cooling
  RS2205-S cooling fins have been reworked to keep the motor height and weight low while maintaining functionality. 
  
  
• 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. 
  
  
• Bearings
  Genuine Japanese NMB bearings ensure smooth, long-lasting performance. 
  
  
• Thrust
  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.
