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.

I buy this one and the new version to make a fast comperisation if you like to have a detailed test like this entry thank you :) ###

Old Version: ###

New_Version: ###

Quality: the new Version is a little bit better, less spherical bearing clearance, and better black mounting plate.###

Weight: the new one is 2.2 gram Havier because it different propeller mounting everything else is same.###

Performance: New one as 20 gram less Trust, and 0.5 gram/watt /less Efficiency and run Hotter!###

my opinion: What I dont like on the new one: its shaft holding its very big 7 mm this made it difficult to make a hole on a 10 mm Carbon squared tube###

Conclusion: for me win the old one!
These motors are a lemon! Bought 4 of them, and all 4 were bad right out of the box. The magnets were glued poorly so they touched the inner part, making unpleasant noise and not letting it spin freely. I had to re-glue some magnets, that solved the problem for some time. After about 15 flights one of the motor started to behave weird: it has start to overheat much more than the rest, starting to spin with half-a-second latency (tried diff. ESC to make sure) and making noise again. It finally leaded to a crash - motor stopped in the air, then restore again but it was too late to stabilize. For the money spent I had not expected poor quality like that.
Very good engine, not a power beast, but very good balanced and silent.
nice motor, gives out 160w on my 2200 3s pulling only 15.7 amps on a 8x4 prop.

caution for those intending to use it on plane, you will have to reverse the shaft as I think it comes more suitable for multi rotors, but the reversing process is very simple

Just a a small prop test for the 2826-1240kv Turnigy Aerodrive .

I didn't use a prop bigger than a 9 inch because of the maximum Amps on the Motor (16 amps) even then the 9x7.5 was to much

hope this helps

Purchased two of these and both brand new out of the box were bad. I place one into a P-38 and almost lost the plane after the second flight. The motor burnt up in air. I was able to land and save the plane for the next time. When I arrived at home, I started to test the next one out of the box and instantly it fried as well. I can not say that I have had a good experience with this motor.
Compared to the Turnigy Aerodrive, the SK3 motors are quieter and smoother.

I used 4 of these with 9x4.5 props, QBrain 25amp ESC, and F330 Quad frame. It flew like a dream, smooth and super fast.

I was fooling around and dumped it in the pool, fried the esc, Lipo OK, ESC fried, and 1 motor fried. The other 3 motors were dried out and work fine.
I purchased two of these to install into a Kenitic, within moments the first one burned out. I then replaced it with the other that I had purchased and it too was bad. I would not recommend this motor, at this time.
Motor bueno y liviano, espero ponerlo en un Pipe j3 hecho de kit, espero sea suficiente
Have four of these on my Hobbyking H4 Quadcopter Frame, plenty of power with 10*4.5 props, Quad weight 1,211g and only need half power to hover, plenty left to load the quad with other gadgets. Will buy more.
