Hello,
I received my order yesterday and one of the two HS-5645MG servos seems faulty as it wont shut up.
It starts this annoying highpitched hum as soon as its powered up, the other one does not do this. Both operate normally otherwise.

Hi Nick,
Can you show us how you connected and controlled those two servos ? (pictures)
An R/C servo will always try to keep a position so a hum sound is normal.
All the best,
