The ONLY complaint I have is that for the low profile servos doesnt support HV. They can only support up to 6.6V which Ive gotten away with 7v but thats about it. You risk damaging the servo if you give 7.4v to the servo.

They also sing to you if you power up the servo but doesnt receive a receiver signal.
