Question
Buzzing noise with slight vibration in my Hitec HS-81 servos.

Not sure why, but when I hook my Hitec HS-81 servos to my Freedom 9s receiver, the servos work great, however, they have a buzzing noise and a slight vibration. If I make them turn with the radio, at times the buzzing noise and vibration will go away and then return if I move the radio arm again. The problem doesn't interfere with functionality, however, the buzzing noise and vibration are annoying. Any insight or resolution into solving this would be highly appreciated.


Thank you.
