Same here. The HS-7955TG in my E-revo chatters (more like whines, standard servos tend to chatter) and the HS-7965MG in my evader makes the same noise.

Its just the same noise that a brushed motor makes at low speeds with an ESC. The servo control board is turning the electric motor on and off many times a second to hold the servo either at center or wherever its being demaded to hold at.
