Product Description

Turnigy SK3 brushless motors are yet another step forward in motor evolution.

Once again we instructed our engineers to develop a motor that would not only rival but surpass the quality of the leading motors on the market today using the best quality magnets, bearings, and materials available.

The result is an outstanding series of motors that are efficient, strong, and robust enough for the most discerning modeler.

All of the SK3 series use quality double-shielded bearings, sintered neodymium magnets (the strongest type of permanent magnet commercially available), and a string wound stator to ensure accurate and consistent winding each and every time.

The Turnigy SK3 motors are suited to modelers who are seeking a top-quality brushless motor without compromise.

Features:
• Double shielded bearings
• Sintered neodymium magnets
• String wound stator
• High-quality finish
• Super-smooth operation

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

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.

Eccellente motore . con 6 celle e un'elica APC 14x10 eroga oltre 1200 watt.
Lo uso su un TIGER della Phoenix ala bassa com un peso in ordine di volo di 3,5 kg.

Very good engine used with 80A ESC, 15x8 propeller and 3000 Mah 6s lipo. Over 1100w of power.
On my extra 60in it drags in unlimited vertical.
I recommend buying, quality workmanship and good looks.
