Turnigy Aerodrive SK3 - 2830-920kv 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 need this for a motor-glider 1650mm in 2s and weight around 900g max size diameter to fix motor is 30mm.
Whitch prop i should put to stay in correct power, maybe 11x4 Folding Propeller & Spinner? (it's just to up sky, not for stay whit throttle ON. I mean i dont need using sandow)
My second question is: is this motor come whit some spare accessory like in the picture presenting motor ?
Yes I have these exact motors mounted on a 500x and the stud pattern is spot on. The only annoying thing is that sometimes the wires come out the wrong side of the motor can so they don't line up with the Gaui's tubes so you have to squash them to get them in.
Hi Seanski, do you know how this motor compare to original Gaui 500X motor? I lost my 500x by a failure in the WKM or maybe a incompatibility with Turnigy 9X receiver (WKM fail safe didn't work, it flew straight away!). Now I'm looking for cheaper motors to fit in a DJI 450 frame and make a low cost gear to keep going.
Hey Velociraptor, Im not sure how they compare, but I have been running my 500x with these motors for quite a few total flight hours now and I'm pretty happy with them. I do balance, and re-oil the bearing on the sk3's before I install them (Using scorpion bearing lube).
If it's a warm day (above 30c) they can get a little hot after a 10min flight, but that's the only downside. I am running super brain 25 fentium esc's, a TMF Pro Controller, Full FPV gear and eagle tree osd and elogger so it's not light. About 1.7 KG flight weight in total. Hope that helps mate!
Slight error above, I'm running super brain 40amp esc's on my latest 500x, and 25amp fentium esc's on another. The super brain 40amp units are exactly the same weight as their 20amp esc's so for longevity I thought it would be a better choice on my second build.
1.7kg? Thats good! More than I had in my lost standard 500X with 3S and I was thinking about 4S to better manage the weight with GoPro and FPV! But I noticed that the cables comes from top of this motor, is that right? Did you manage to change that or just used like that? Do you mind charing what propellers size do you use with that?
Yeah np at all, I'm using standard gaui 10 x 4.5's. You are right to consider the 4S path but once I took a couple things into consideration I went 3S and it's going really well. The slight higher KV of these motors gives good thrust with the 10 inch props. If you go to 4S you can't use these motors, so heavier units would be in order. The 4S path seemed in-efficient to me considering the extra battery weight, bigger esc's and motors etc, as you would start to push total weight out towards the 2 kilo mark, fully laden. I'll take a couple photos of mine with lid off so you can see the rig I'm running.
Sorry forgot your question about the motors. Mine are mounted upside down and I've used the bolt on prop shaft that comes with the motor. It bolts to the back of the can with 3 screws. See photo
Wow! It's looking really good! Congrats Seanski! Thanks for sharing! I will be using my DJI 450 frame that came with DJI Wookong and is all that's left from my lost 500X!
Let's keep in touch, I have the same user name in rcforums, you can find me there if you want. And congrats on your Quad once again, well done!
Cheers Velociraptor! I'll look you up on the forum, would be great to see your quad when it's ready. I'm heading out for a long-range fpv test this weekend so hopefully will have some quality video to put up.
iam thinking of installing this motor in my extra 300 944mm , will it be to stong if not what size prop must i use?
for now i have this motor in my slow stick. had to use carbon rods in the wings. with so much power on tap the wings would flutter. i'll use this motor for a bit before using it in the Phoenix 2000. i'm concerned how long this motor will last. i'll report later how it does after a few months. but for now, i like it.

heard the stock motor had heat issues in the pheonix 2000 so i swapped the motor with this sk3 2830-920k. power is about the same as the stock motor but cooler.
i had three flights with the pheonix 2000 and all resulted in the plane floating a long time with a cool motor and esc. the sk3 motor is light efficient.
good motor. no regrets. i'll report more later.

trés bon moteur, monté sur un gaui 500X (faut inversé l'axe de sens) me donne entière satisfaction

Received 2 of these today and wired them both into my twin seaplane. Very nice motors, running cool with 8x7 three-blades and 25A esc. Only complaint is the bearing noise in one of them.
Does anyone have any suggestions / advice on dealing with bearings in these guys? Normally it wouldn't bother me too much but the plane is designed to run quiet and the noise is spoiling the vibe.

I now have about 14 of these motors in service and overall they have been great. Two quads and a y6 multicopter all running these motors means I can keep costs down. One thing I have found is that the one of the 3 screw holes in the motor can for rear mounting the prop shaft fitting are threaded, which makes them doa for my purposes.
I am running 10x4.5's and 8.5x6's with heat mostly around the 55C mark.
