Turnigy Aerodrive SK3 - 2822-1090kv Brushless Outrunner Motor
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.
I use an SK450 quadcopter frame, and I am looking for a set of motors to upgrade to. Right now I am using 4 Turnigy Aerodrive SK3 2822 1090KV motors (these).They fly fine with my quad, but I plan on adding some FPV gear and I don't think they can take the weight very well. Does anyone know of a motor more powerful (more lifting weight) than my current motors, but draws less than 15 Amps (for my ESCs, the current motors only draw 7A)? If you do ,could I still use my 8045 size props? If the motors draw more than 15 Amps, that is fine, but for space issues I don't want to have to use ESCs bigger than a 20A size. Thanks! RC2211
I found the perfect motor for what you're asking the 'FC 28-22 1200KV' they're only 6.99 and handle up to 15 amps so you could keep your existing ESC's, all you'll need are new props, 10x4.7 SF are perfect and will fit your frame no prob, keeping your amps low with small props is impossible, you'll need high KV motors which bring your amps up and decreases stability, the bigger props will help keep your camera steady and vibrate a whole lot less, providing you balance them first of course :)
Thanks for researching all of that, but since posting this (on 12/11/13), I have bought and received 4 2822 1275 SK3 motors. They are performing well with all of my current gear so far. Now to buy the FPV... Thanks again for my though! RC2211
Thanks, my 8045 props already make it somewhat warm. My new 1275 motors should lift much more than the FPV gear. Thanks again.
The engine is manufactured in a good quality! All in all a satisfactory product. Price performance is top!
The screw propeller holder is attached with three screws 2M.
The gap between the stator and the bell is small and the detent torque is low - normal for a 14 pole motor with 12 slots.
The cables of the phases are not enamelled copper wire, 20-24 AWG wire instead. Great for soldering.
I run the engine in a 8x4, 5 prop with a 12A blue HK series with a 3S lipo - without any errors.

Very nice little motor.
It is a comparable motor to the KDA 20-50S.
33g with 2mm gold connectors and the prop holder (fixed with 3 screws).
The 3 screws are not the best quality, so don't screw them too strong, or the winding will break.
I have measured this motor (and the KDA 20-50S) with my Eagletree gear and uploaded the data to drivecalc. You can use this program to try different props. and find the right configuration.
(Turnigy SK3 2822-1090 - timing high)
perfect motor for small quadcopters:
measured for example following combination:
Turnigy Plush 10A
Maxx Pro. EPP0845 Prop.
thrust: around 425g
