2 Pcs JDRC SG90 9G Micro Mini Servos SG90 Servo for RC 250 450 Helicoper Airplane Car ship Boat Robot MG90S

Ordered 2 drives. Both work. One is assembled so that between the sections of the case there is a gap of about 0.5mm, it and buzzes at work noticeably louder. It is necessary to pick up the reducer, I hope for improvement in work. And so it looks neat, you can buy a sample.
