RotorStar Series brushless motors offer the absolute best quality, performance and value for your high performance helicopter model. Each and every RotorStar motor is thoroughly inspected and tested to ensure the high efficiency and top performance required for meeting the demands of 3D helicopter pilots.
RotorStar Series motors are top quality brushless outrunners designed specifically for use in todays high performance helicopter models.
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 surpass 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 RotorStar motors are suited to modelers who are seeking a top quality brushless helicopter motor without compromise.
