Turnigy Aerodrive SK3 - 2118-3100kv 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.

here is a photo of how I got it to work. big thanks to kenstogie. now I know how to use this. Rad little motor, lots of power, made with precision. Stretch the prop savers to squeeze them between the bolts and uppr motor assembly. if you have to loosen the screws, mine came with loctitealready coating them, just make sure you keep the screws evenly screwed in or out or you will unbalance the motor.
i just got this in the mail to put on a bonsai, but i am having a heck of a time figuring out how to mount a prop on it. i would like to avoid changing the shaft, is the little nut on the reverse used to adjust the length of the shaft or is it assumed that you have to buy a different shaft if you want to mount a propellor to it? Also 10 amp esc sufficient? after i get the shaft ready i assume a 2 mm collette will work.
I don't have this motor but if you look at the screws on the first picture they are for a prop-saver. If I am correct..... just put the prop in between the two screws and put on a prop saver (like a rubber band that straddles the prop) and your good to go.
1. im going to buy this motor for my Bonsai. does it fits with this Prop? PRODUCT ID: H5011A the 5*3 propellers.
2. what is that "O" Ring used for?
3. is there any accecories that i have to get to attach it with that 5*3 propeller?
4.i never attach any prop with this kind of motor (having a tiny shaft length). how i would do that? picture really appreciate it.
thanks all, happy flying..
It is better to have a slightly larger esc for a buffer point if you can afford it. Also, depends how heavy your quad is, mine is about 335 with battery and it is fine. I did however have issue with getting the props to stay on at high speeds.
I have 3 questions: 1)Is this motor better than the: HK1612-3200 for the BONSAI-EPP? 2)what propeller do you recomend for the BONSAI? 3)how do you fix this motor to the bonsai? (does'nt seem to have any fixings like the other motor) Thanks!
Blackjackr, If you do go 3S, don't use a prop over 3.5 diameter. I had a 3S on a small 2900kv motor and burned both the motor and 6A ESC with a 5x3 prop. After bench testing, I found that small stryker props (3.5 inch) worked fine with 3S. Hope this helps and happy flying!
dumb question, but "5x3 sport"... does HK have that? All I could find in 5x3 (or 5030) was the GWS/GWS-like ones.
Also... I have a GWS-style E-5030 and this motor draws 5 amps at barely over 1/2 throttle with only a 2S, 20C, 750 mAh Rhino. I briefly popped it to full throttle and it went up close to 6 or 7 amps. (only did that for a few seconds - NOT suggesting anyone try that given the rated max is 5!).
Going to try a 4x something prop next.
Thanks for the reminder! It got put to the side due to other projects. I just wired it up with a GWS (HK version) 4040 and saw 88 grams peak thrust at 7.5V with 5.2 Amp draw. Obviously this was a 'burst' rate and not sustainable either for long periods.... however, as some would say it may 'unload' in the air. I also just tested at 6.98V, 4.5A, I got a steady 75 grams of static thrust. So.. for a 4040 prop you'll need to plan appropriately for what type of model you want to fly ... eg. for a 3D plane I wouldn't go more than ~ 60 to 70 g AUW. Your mileage may vary though... hope this helps. If you want me to test more props let me know.
I just tried a GWS 5030 again for kicks and at 6.7V under load (static) I got 135 g thrust at 5 Amps draw. So, that said, I suppose one _could_ stick with the 5030 and 'go easy' on the throttle for the first part of the flight. Thanks. J
i just got this motor it is very small it is well made i just thought it was bigger in the pic iam still learning the tech stuff i have no clue to what it used for dose any one know my e mail is francismiller79*gmail**** thankyou
The motor was delivered in a box, including all attachment parts like motor mount in 2versions!! and even screws! Perfect deal for this motor. I use it for my Hacker Sky Fighter and I'm totally satisfied with this powerful engine. With 4x4,5 prop and a 2s 490mAh I can fly more than 10 minutes. If you compare it to the original Hacker motor, it is the same performance. 5 crowns in all categories, thank you Hobbyking for this ingenious motor.

I have bought 4 of them. 1 has loose copper wire inside the bell and stuck between the bell and stator.

Decent tiny little motor, pulling about 6.8A with a 5.3 prop on a 2s nano-tech. Wish the prob saver was a tiny bit longer just to hold on a bit more but works well enuff.
