Turnigy Aerodrive SK3 - 2826-1240kv 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 this Motor with an 8x4 APC prop, it works very well and with an 12a turnigy Plush i can go 4 minutes Full throttel without went hot!
One of my favourite Motors for Combat Wings!
I Hope i helped you *)
According to the castle creations site flight calculator ( ive found it to be really pretty accurate). The best combination would be something like
ESC plush 12A with 2 A liear BEC
Motor Aero drive SK3-28-26 1240
Prop APC 9X4 electric
thrust to wieght about 1.3
Aprox 40-45 mph max
about 10 A max
If you over prop it th current goes thruogh the roof.
The motor comes with two prop adapters. A collet adaptor and a bolt-on adaptor. The collet adaptor will clamp onto the shaft the comes out of one end of the motor. The bolt-on adaptor bolts onto the other end of the motor. I guess you can choose which type you want to use, although I prefer the bolt-on adaptor for multicopter use.
I bought 4 of these motors for a Talon v.1 quadcopter frame. The 3.0mm shaft sticks out the bottom and prevents mounting on the frame. I want to either (1) push the shafts through or alternately (2)cut the shafts flush with the base of the motor. Can anyone advise how to achieve (1)
why cutting the shaft? I checked the mounting plate of the Talon on a picture and I see a hole for the shaft on it. even if yours does not have a hole i guess it would be easier to open a hole on the frame than modifying a motor.
if you loosen the grub screw found in the top of outrunner bell, you can press the shaft through the motor. remove the bell from motor to make it easier. then carve a groove in the end of the shaft for a c-clip to stop the motor pulling apart.
the cross-shaped bit of metal can be used for mounting the motor onto a firewall, fix it to the base of the motor with 4 screws provided. the two other objects are prop adaptors, one will slide onto the shaft and tighten up when you tighten the nut, the other adaptor bolts on (with 3 bolts provided) to the outrunner bell if you want the prop on the other end of the motor.
Hy Gentleman. I'm looking for a motor with mid power in a 28 size. It jumps from "SK3 - 2830" -> 187W of Power to "SK3 - 2836" -> 405W of Power. Is out There nothing in between, specialists ? Thank you, Leo
We want pictures of these SK Series motors disassembled. So we kann see, how "well made" they are. The old 3542-1000KV SK Series for example had no 0.2mm laminations but 0.3. The Turnigy 2836-1200KV has them. So the descriptions aren't right alltime. What are the quality materials in these motors? What kind of magnets, what kind of laminations and what kind of bearings? The old ones where trash.
The old bearings you mean? I just bought 5 motors and I thought I'd have a nice quad in the air but the vibrations are so bad I cannot fly it with confidence. I know the motors are overpowered for a 330mm F330 frame, but the vibrations are just insane. Two of the motors seem to have either bad bearings (they click when you spin them around, always in the same place, you can hear this when they're idling) or they're rubbing against the stator. Also, the material used is very soft, I stripped a screw when I installed the prop adapter, wasn't too happy about that.
