Perfect Motor for the Changesun 90mm 12Blade Fan on 6s or 8S!
Turnigy SK3 Motors are the next leap forward in motor quality and design. We instructed the engineers to source the best quality magnets, bearings and materials available to them and develop a motor that would not only rival, but surpass the quality of many leading motor manufactures on the market today.
The result is an efficient, high caliber motor using quality double shielded bearings, sintered Neodymium magnets and a string wound stator ensuring an accurate and consistent winding each and every time.
The Turnigy SK3 motors are suited to modelers who are seeking a quality brushless motor without compromise.

This motor really zooms through the air in my FLYFLY Bae Hawk. Does anyone think you could put 9S or maybe 10S with major throttle control? Or would it cook the motor?I have Had a loss on the Fly Fly T45 the esc caught on fire?Lucky for me i had an external bec connected and managed to land the plane and put the fire out.I recovered the motor and re used it in a hobbyking bae Hawk. the esc that i had in the T45 was from hobby king it was a turnigy delux 120A,it must of had an issue as i could not get full throttle with this motor and obviously there must of been a problem with the esc.So i purchased a Castle creations Talon 120 HV esc for this motor and now the Bae Hawk from hobby king screems at full throttle.
See youtube clip of this motor with change sung 12 blade edf unit just copy and past the link.
https://www.youtube.com/watch?v=iG6YHyokXtkLove this motor in the Changesun 90mm 12 blade EDF. Gives 3000watts of power on 8S with a great sound as mounted in a Freewing F-15. So good I bought 3 more for future use.https://www.youtube.com/watch?v=xP6ZXGBbNcQ ADD THIS LINK TO YOUR BROWSER JUST COPY AND PAST IT IN TO YOUR BROWSERI ended up installing this motor with a 90mm changesung 12 blade fan and installed it in to my fly fly T45.I must say the motor runs smooth with out any issues and has plenty of thrust.I am very pleased with its performance.here is a video.
https://www.youtube.com/watch?v=xP6ZXGBbNcQI used this motor in the "High Performance 90mm 12 blade fan" (Change Sun), powered by 8S 5000mAh Turnigy 40C Lipos. Starting power is 3000W, settling to ~2700W mid flight. Note that I limit the throttle output initially as 1500Kv is a bit high on 8S, so this avoids blowing the 120A ESC. After the Lipos have lost some of their initial charge I flick a switch on the Tx to enable full power. The motor is smooth and tough. It replaced a different motor that was recommended for that fan, but it blew on climb-out. No problems with this motor!received this edf motor in its own turnigy box was well packed will post a review in the future once i install it in to my MB339 jetTop quality motor for EDF. Fits Changesun 90mm 12 blade (with 8mm adapter).
Perfect for 7S and 8S.
8S peak 3100watts/107amps settles to 2950watts/104amps
7S settles to 2400watts/94amps
The CS fan must be of the stronger version or the risk of fan failure is high. The fan must be secured to the adapter with a sandpaper washer in between to prevent slippage at high power (which will throw off any dynamic balancing you may have performed. Do not run fan at high power unless it has bee properly dynamically balanced or fan failure is likely. If you don't know how, get some help from and experienced EDF builder.I use this motor on a 12 Blade CS with 8 cells 2X 35C 4c 4500, The numbers I got are battery @ 33.38v 2773.7Wp 100.29Ap 18.8Wh......This motor fits perfectly in the CS 90mm duct fan.
