These 10pcs SG90 9G micro servo motors have a completely new redesigned PCB and control system to provide more accuracy. Its internal gearing and motor are also upgraded to improve dead bandwidth and centering. SG90 9G micro servo motor is far more accurate and safe to use in aircraft which require precise servo movements and perfect centering. Strong and beefy with very little signs of flexing.
