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.

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

Seems OK.Waiting on ESC to fire it up

Nov 04, 2022

Looks like I snagged the last of this motor size from the closing Oz warehouse. It is for an old 0.46 size trainer I am resurrecting so would have preferred 600kV but fell sure this motor will still do the job. Plan to match with a 13x8" prop.
Motor from Oz warehouse arrived quickly and looks good. Very frustrated that after 3 months on order the accompanying 70A ESC from HongKong warehouse still hasn't arrived so haven't fired up the motor yet. Seems no way to change that order to another in-stock product......VERY frustrating!!

Motor performs well but more technical info is needed.

Jan 28, 2021

A technical specs sheet is needed. Performance data on 3s, 4s and 5s, props used, max amps, Wattage, Thrust, Efficiency. Note: Leopard, BadAss and most other motors have spec sheets.

I use this as a replacement motor for my 2-meter Parkzone Radian and it fits perfectly! And, works great! I just had to purchase another ESC though. But WELL WORTH IT!

SK3 4240-530KV

Nov 06, 2020

Waarom wort er niet meer aangegeven gelijk vroeger de celen en daarop de prop ?
Vroeger werd er ook een vergelijking gemaakt met de waarde van de elektro motor tot de methanol en eventuweel de trek kracht van al die dingen is er niets meer te vinden dit is niet klant vriendelijk.

Just received the motor, very disappointed in the quality of the supplied hardware. Why are these motors not supplied with socket head bolts for both mounting the prop adapter and motor mounts, further the prop adapter is too light for a motor of this rated power driving a 14X7 prop on a 5S system. further the bullet connectors are too small to fit my 3.5mm connectors on the ESC. A lot of fiddling about to get it right, I will report once the motor is in service. My recent purchase of a SK3 motor was also disappointing in the same area, though it performs brilliantly in the air.
