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.

Motor arrived quickly, looks to be of good quality, but the internal beeps are very quiet. Tried with the HK YEP 80A and with my new Castle Phoenix Edge, same result, quiet beeps.
HK say's the motor has 14 Poles, but that is not true it is a 6 Pole motor. Magn. arranged NN-SS-NN-SS-NN-SS. Results of my own pole test.
Motor runs very cool and quiet with my setup.
A second motor is on its way and hopefully the beeping is of a normal volume than the overall Rating can be 5.What's going on guys I got this motor after my typhoon 1900kv burned up in my trex 500 after 6 of hard flying the fit an finish of the motor is better then the typhoon an it have plenty of power on tap for flying 3d big air the only issue I have is they list this motor as being 14 pole motor when it's only a 6 pole motor besides that I'm starting to like this motor
