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
