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 test this motor by using Turnigy watt meter with the results 636 watt and 48 amp with 12x6 Prop. And 4s Battery. I install this motor to t28 Trojan (3.46 lbs) and Here is this video https://youtu.be/1czGmAb8qdk

This motor is incredible. I put this in a Great Planes Proud Bird because the previous Eflite 1250kV motor on 4S 3000 with a 10x9 APC sport prop smoked. I can't say I was surprised given the large prop and the motor came down hot as heck..

This motor I put in the same plane, and since it's much lower kV, I run it on 5S 3000 to try and make up for some of the difference. Running 2:00 flat out full throttle, this motor draws 70-80 amps average, 1400-1600 watts, and this is continuous.. No breaks in throttle until the battery gets down to 3.8V. I fly my plane without a spinner (did this with the Eflite motor also) to allow good airflow through the cowl into the motor inlets. The most shocking thing about this motor is that after a continuous 75 amps draw and 1500 watts, the motor is almost ambient temp. It barely has any warmth at all. So not only does my plane fly faster now (16,000 RPM vs 13000 RPM), generates much more power, this motor flies MUCH cooler than the EFlite, costs $40 less, and will allow me to prop up even more. I think a 10x10 maybe be next. To say I'm shocked by this motor is an understatement. I'll be getting SK3 motors over EFlite or Rimfire every time if there's a size that fits the plane I want.

I was looking for a suitable motor for my Lanyu ASK 28 with a 2600 span. This motor with a 11x7 folding prop in combination with a 60 A YEP ESC and 2200 25 C Zippy compact Lipo is a winner. Just in the beginning I use full throttle ( 28,2 A at 11,4 V is 322 W static measurement) and than around 30% throttle gives me about 10 minutes fly time and still enough power for an extra landing circuit. Motor and ESC working flawless and the price is unbeatable. Good value for your money. Fast delivery, thanks HK

Excellent motor! Used this in my 48" Extra 330sc and it performs very well. Tested using 12x6, 13x6.5 and 14x7 wooden props and they all give strong thrust & power to perform 3D acrobatics, though 14x7 gives strongest power.

Also the motor is surprisingly quiet and doesn't make alot of noise which is very nice.

Overall a great motor, highly recommended.

Mounted on a plane HobbyKing MXS EPP / Light 3D Plywood 14x7E prop, the ESC must be 70 amps; flying at a height of 2,300 meters above sea level using a battery of 2,200ma 4s 40c.It provides six minutes of flight combined 3D and pattern.
Incredible engine power and barely heats, coprare more! Youtub: PT_kTyeoHNU

4 flights so far on my PA XR52. Using a Vox 13x5 prop with a 4S battery the power is great. The previous hyperi*n motor couldnt handle all the knife edge spins and was getting a bit rough, so will need to see how this one holds up. Nice and smooth motor, and seems pretty solid so hopefully it is up to some hard 3D flying!.

One of the front bearings has gone from slightly rumbly when purchased, to rather noisy after only 2 flights. Other than that, its been a good motor so far with great power and a nice finish. Good value for money but the bearing issue stops it being a 5 crown product for me.

Bell was nicely balanced, the prop adaptor is well centered and everything fits great.
Drawing 40A peak with a 12x7 master airscrew prop on 4s.

Mounted with a 12x6 folding prop an 4s configuration is great power for a go discover or a similar class airplane. Ps: I mounted in a Go discover, but I had to modify the inner space of the plane.
