First of all, I bought it for the XK K120 helicopter, but I haven't been able to fix it yet because the controller is K110s, the motor controller is 12A 2s, and it still needs a tail rotor controller to fly. However, I can proudly say that I managed to install the tail rotor controller in the K110s helicopter and it received a Happymodel brushless motor. It flies very well 🙂

Először is az XK K120 helikopterhez vettem, de még eddig nem sikerült rendbe tenni, mert a vezérlés K110s, motor vezérlő 12A 2s, még csak egy farok rotor vezérlő kell, hogy repüljön. Amit viszont büszkén mondhatok, sikerült a farok rotor vezérlőt, beszerelni a K110s helikopterbe és kapott egy Happymodel brushless motort. Nagyon jól repül 🙂

I really like this upgrade. Im not doing crazy 3D flying, but practicing wild orientation flying in the living room and it holds the tail very well.. Only in idle up 2 (highest headspeed) doing agressive pitch pumps the tail breaks out a little.. The bearing needed a litte drop of oil and now the motor runs very smooth.. I wish it was a little less expensive and came with other color rotor than that ugly blue.. (but other 4 blade 35mm rotors in different colors are not hard to find).._Happy to have a longer lasting tail motor now and dont have to replace the standard motor everytime due decreasing performance and battery life.
