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.
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.

perfect motor for small quadcopters:
measured for example following combination:
Turnigy Plush 10A
Maxx Pro. EPP0845 Prop.
thrust: around 425g
Bought 2 pcs, but only bench tested them so far: 7.4Amps at 10.4Volt (semi charged 3S LiPo) with 8x4.5" prop. Quality seems fine.

These motors where what I used for a quadcopter build a year ago and lets say they are a great choice. Flight time wise, I'm flying around 10 mins with a 0845 prop, 3s 2200 mah lipo, and 10amp escs. These motors are great for the price, they do get a little bit warm but not close to hot.
As for build quality, there is nothing to complain about except that one of the motors did get bent from a 25ft fall, as the bottom plate (the plate from where the shaft protrudes) seems to be the weakest part of the motor but then again it was 25 feet.
These motors are
Over all, I will buy these motors again as they are cheap, preform well, and look good on my quad.
Note-If you are going to get this motor, get some higher rated esc's because my 10 amp escs do get fairly hot, even at winter time.
