Turnigy Aerodrive SK3 - 3542-1000kv 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.

Probably not. That motor and prop combo will try to draw 600-700 watts. With a 3c 11.1v battery that would be around 60 amps which exceeds the 45 amp max current listed. You should try a 4c battery which will keep your amperage at right around 45 amps.
Nathing is right, it pulls 60 amps with that set up, (actually 62A peak). But it's not been a problem so far. If you only use full throttle in short bursts then the motor seems to cope fine.
I'm not sure what's meant by 'try a 4c battery'. the lowest c rating available these days is about 20c and anyway, using a low c number wont 'cap' the amps. If you want to reduce amps you would have to prop down.
If you mean a 4s battery then amps would be through the roof with a 13x6.5 prop, way over 100A I'd guess, right before the smoke came out.
It depends on what battery and blade dimmensions you use.
I run this motor with 3S Lipo 3300mah 35/50C.
My experience: dimmension / thrust / minutes (mixed flight)
10x6 / 1700g / 15:30*
11x5 / 1900g / 13:00*
11x7 / 2323g / 10:30*
12x6 / 2444g / 09:00*
I am a newbee and i am buildind a DJI F450 quadcopter. Will these motors fit the Quad - will it make it fly missile fast using 4 cell battery and Gaupner E 8.4 props.Also ESC's should they be 30A amps or 40's. Thank you.Appreciate the info.
hello, what size prop do you recommend for this engine?
I came up with Gee Bee R3 1400 HK Turnigy AE-45A Brushless ESC 4s 3600 mah
but I'm afraid of being light on the controller.
I thought putting a 13x8 :)
I run this motor with 3S Lipo 3300mah. Plenty of power for FUNCUB :). I have these blades: apce, Turnigy wood "D" and "Cherrywood". My experience:
dimmension / thrust / minutes (mixed flight)
10x6 / 1700g / 15:30
11x5 / 1900g / 13:06
11x7 / 2323g / 10:30
12x6 / 2444g / 09:00
ESC: if you plan to use 6-7 servos (flaps and tow), I recommend the minimum 50A ESC with 5,5A BEC. Optimum 60A ESC or higher.
I encourage you to try different blades and see for yourself. E.g. I want to do more aerobatics or tow a glider = I put 12x6. I want an easy flight with max time = I put 10x6 or 11x5 on my FUNCUB.
Hi, I need an advice. I bought this motor and I don´*t know if will bee 50A ESC strong enough? I use 3S 25/50C (nanotech) baterries. The motor is for the Funcub and i will have propeller 11x5 or 13x5. So.. can i use 50A ESC? Thanks .)
if you plan to use 6-7 servos (flaps and tow), I recommend as the minimum 50A ESC *with 5,5A BEC*. Optimum 60A ESC or higher.
13x5 blade is wastefuly too big. I use 11x7 for aerobatics and 10x6 for longer flight times.
Hi Does anyone know how many poles this motor has as I have a turnigy superbrain esc with an onboard recorder from which you can download performance data. One of the questions the software asks so that RPM and other factors can be calculated correctly is how many poles does this motor have and hence the question
Thanks for the answers but my confusion reflects the answers exaclty ie are poles equal to the number of magnets or not. Many of the articles say that this is not necessarily the case. So do you guys have any further info that will help clarify
im using for a 3D 3600mah 3S 30-40c with APC 13x6.5 prop..and for sport same batt with APC 12x7 prop i have a video at that motor page ,with trust 55A ESC barelly warm setup or go to you tube and look for 49inch yak 55m markham park show you amps,watts. etc hope it help
I dont see any circlips on the shaft. Is it possible to slide the shaft through to the opposite side from the photo, and then use the collet adapter? I dont think the 3 bolt arrangement is the way forward. Should have stayed with the 4 bolt. This is going to cause problems. . .
The shaft can be pushed through to the other side. Loosen the set screws, remove the cirplip. I use a drill press with the jaws all the way shut as a mechanical press to push the shaft through as it does take a lot more force than one would expect.
Hi Colt1873 - when I push my shaft thru the other side there is no place to re clip the shaft. Thus there is a tremendous amount of play in the shaft and motor cover. Does yours do this? Can you even operate the motor in this state?
Try a 12 x 6 prop if you have a 60A ESC & the motor is cooled sufficiently. On 4 cells, you should see approx. 53A & 860Watts static. 177 Watts per pound in this case should be sufficient. If 12" is too much diameter, go down in 1 inch steps, but add an inch to the pitch. I'm getting similar results with a 10 x 8.
On a 3S pack I would try an 11 x 8e if you're looking for speed. An 11 x 5.5e for better verticals. Those are just starting points* be sure to check your current draw with an amp. meter. You might be able to go to a 12 x 6, but it will probably be close to the max. amp. rating, if not over.
Thanks, MtDmitriy, for the additional input. I suppose I'm overly cautious about loading a motor, so it's good that someone else has added some information. The important thing, of course, is to use a meter and check the load produced by each propeller/lipo combination. I'm always surprised by how much these motors can withstand.
I use this motor on a Multiplex Funcup, this motor realy rocks, starts on 1 meter and goes vertical accelerating. I normaly use 3 cell 3600 batt, and it tows easy gliders up to 2,6 meter, and I also have towed a 3,2 meter and 2,7 kg F3b glider. I use a 4 blade 6x10 prop from hobbyking P 51. or 13 x 4 prop. Readings. 13x4 prop 3 cell 30 Amp 349 watt 4 cell 48 amp 766 watt (And the nose on funcup go into wild flutter)
12x6 4 cell 53 Amp 864 watt
12x6 4 blade (P51 prop) 64 Amp 989 Watt (And no flutter in fuselage) But the motor wont last long with full power. On this video i use 3 cell www.link

moter not only looks nice but performs well...have it ina large cesna foomie on 4 cells 13-4 prop and it goes great... will experiment differant props and batts...electric is great
