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

Benutze Ihn für einen 4m Segler mit 5 Kg Gewicht und nur 6S. Geht fast senkrecht wenn man will, bzw. in 15 sec. ist man in der Thermik, danach hat der Motor genügend Zeit sich abzukühlen. Toller Motor.

The quality of the motor on top! Just as advertised. The motor is wound with a thicker wire, cable laying flat, spilled paint. The motor has no vibration, bearing all good. I am glad that quality products begin to appear remarks of good money in my favorite store. Indicators could not do that because the engine is very powerful, it will break my stand if I test it. Putting on the model and run it, the fuselage is not possible to hold in their hands. I have tested the battery 6s5000mah25c, Prop 17x10.
