Product Description

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 surpasses the quality of many leading motor manufacturers 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.

Another poor design from H King

Jan 04, 2022

Bought a couple of these for a project and then discover that the output shafts have the "flat spot" (for grub screw) hard against the face of the motor...WHY????? Makes no sense. Cant even be bothered elaborating more - just sick of having to deal with HK junk.

Turns a 17x8 prop on 6S

Oct 23, 2021

Strong and efficient. Lots of power and barely gets warm turning a 17x8 on 6S on a Grand Tundra. Great choice for any 60-70" aerobatic plane.

Good value motor

Jan 15, 2021

Only 5 flights, but no problems yet. Connected to a 6s pack via a Castle Creations 100A ESC and with APC "E" props recorded the following:- 11x8 20A 490W 12x8 27A 655W 13x8 33A 790W 13x10 44A 1030W 14x10 50A 1177W
Hope this is useful. I personally wouldn't run a motor of this size at over 50A.

Turnigy SK3 series motor

Aug 14, 2019

These are the top of the line motors, if you can find better, buy it. I have several of the SK3 series motors and have yet to have one even hiccup. They run beautifully, are well balanced, perfect draw on the ESC'S and LiPo's. Best product for the best price.
