The 
Blue Bird M15V is the new kid in town, say goodby to KST?? Perfect for sail planes, dlg gliders, 3d airplanes and more of your RC high end toys, these M15V servos are precise, very fast and offer an unbelievable torque of 7.5 kg-cm / 104.2 oz-in on a 2s battery. These blue bird servos come in an all metal case and a magnetic sensor instead of the traditional potentiometer where the pot over time wears out.
These Blue bird BMS-M15V servos are very quite unlike the competitive digital servos where the buzzing sound can get quite annoying.
