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
Hello i am wondering if i can cut the bullet connectors off of this motor and solder the wire to my esc's wires. Will doing so affect the motor in any negative fashion? I know some motors wires are the extended windings of the motor. Is this true for this motor??
You are OK shortening the motor wires, just not too short. Do not get too close to the motor can as you can cause damage to the way the motor runs. If you're just cutting the ends so that you can put on new connectors, then you are OK to do so with this motor (SK3-2822-1090)
The Motor is only rated for up to 3S so you probably would burn the Motor out.
If you wanna calculate how much power you can get with a quad or a plane use ecalc .ch They have a really nice setup to see what works and what doesn't.
I tested it once, so guessing you have 8x4.5 props and 3S lipo and it only weighs about the 600gr you can life more than an extra 500gr and flighttime depends on the mah. With 2000 is about 6min
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.

Trust 340g on APC SF 8x3,8 at 12V and 5,2A . Good quality but one of four motors have crashed bearings .

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
