Turnigy Aerodrive SK3 - 2826-1130kv Brushless Outrunner Motor (USA Warehouse)
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.
Wiring Question: OK, forgive my ignorance - these motors just arrived with the ESCs. The motors have 3 black wires, all unmarked. The ESC has 3 output wires marked A, B, and C. WTF?? Does it not matter which ESC wire connects to which motor wire? Of course, there is not a single instruction with either product, and nothing on this here. Thanks for all help. -G
no it does not matter at all. unless you motor is rotating the wrong way. if that is the case just switch any of 2 of the 3 wires to allow it to rotate the opposite direction. Plus Make sure that the the side of the prop is always facing the direction the airplane is going to travel if not you are going to rob yourself of power and efficacy plus the amperage use goes up.
I have a quadcopter with product ID 11879 motors on it (A28M), and one of the shafts came unpressed. I'd like to upgrade to higher quality motors without decreasing performance. Would these be good replacements? Or is there something better?
Also, do these mount the same as my old ones, where you screw them onto the frame at the bottom, away from the end with the shaft sticking out?
So I just bought one of these little motors and I must say that quality is really good. I am very pleased with it. I mounted this on these "Electric Motor StandOff Mounts 10mm Small base (5pcs/bag)" sold from Hobby King. I had to modify the mount slightly.
GWS EP-8040 Prop, 3 cell Lipo, 7.54 Amps
APC 8x4-E Prop, 3 cell Lipo, 9.49 Amps
The motor comes with a prop adapter that will fit on the bell end of the motor, so you can mount it either way. (Second picture, silver adapter, top left)
I have 8 of these motors on two quads. A couple of them seemed like the bearings were a bit rough at first and they were noisy when running. After a few hours flying time they seem to have smoothed out. Plenty of power using 8x4.7x3 props. I have tried running 10x4.7 two blade and they fly great, but seem a bit warm after an 8 min flight. Quad is more responsive with the 8x4.7 three blade. Hovers at half throttle with both size props. I have some 9x4.7 two blade on the way and will update as to how these work. So far so good. I am running the HK SS Series 18-20 amp ESC and they work fine with this motor. I like the bolt on prop adapter that come with the motors. I have crashed several times with no motor or shaft damage, even though I broke all the blades off the props. I will buy these motors again for my next project. It's going to be real hard to beat these for the price.

These are nice motors. I bought 3 of them a year ago, and have been happy with all of them. My favourite prop for these has been a BlueBird 9x6E, basically equivalent to the APC 9x6E. (Note that this is NOT the SlowFly prop, although the 9x4.7SF is also decent.) With 2200 mAh, 25C, 3S LiPo and 15A to 18A ESC, one of these will haul 25 oz (700 g) around the sky with authority. Search YouTube for "flying over Rouge Beach" for one example.
