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.

Recommendable

Great engine without problems with a very good efficiency, not only for the skateboard. I use it with 12S on an 8 kg tow model and got it a long time ago at a special price of around 57 euros - thanks HK!

Good quality, i am using it for over four years in underwater scooter equipment with over 50 units in the field. no problems until now. The integrated cooling fan does a good job.

Very decent motors!

Jul 17, 2018

Hi all. I think 1 video is better than 100 words: https://youtu.be/b0w6h26HBBw
More to add, sk3 (starting from 64mm length) motors are unique by having extra bearing, which helps a lot to handle radial load. Sure, there are applications, where it doesn't bring much benefit. But it's definitely nice to have in esk8.
Regards.

Suprising torque

Mar 26, 2018

*This review contains no scientific data, only anecdotal and personal feelings.
So I bought this as an upgrade to my electric longboard. The original motor was some generic 5054 that worked alright but could not move me up even the slightest of incline (I weight in at around 285-290lbs) even thought the board was rated for 290lbs. This motor was so strong that it broke the original motor mount after the first use so I had to fabricate a new one. Even though the new mount was 1/8" thick steel the motor was able to bend the plate when using the engine braking. I have since reinforced the steel plate with 1/8" aluminum angle stock, and also ordered a better pre-made mount. The shear amount of torque this motor generates is very impressive, it has no problem moving me from a dead stop and actually gains speed while traveling up slight inclines. Basically, I'm super impressed with the power of this motor, just wish I could fit two of them on my board.

Good buy

Great product for lightweight electric vehicles. I'm currently using this motor with 8s lipo to power a fixed gear bicycle (friction drive). Motor is spec'd for 14s and 70amps, but gets me (160lbs) up to 18mph at 8s with about 20amps.

Rock solid construction, and the windings arent done too bad at all either. Actually purchased a 2nd just to avoid shipping if i need another one. If this is in stock and its in your budget buy it now, sometimes take a little while to restock.
