My Spektrum s6240 is chirping when it turns.. Ive never had this sound come from a servo. I took it apart, blew it out and greased the gears to no avail. Anyone have an idea?

Its normal for digital servo's. It comes from the motor getting high frequency control voltages, as you always can hear brushed 540 motors beeping when getting power.

Hhmmm, normal? Ive never heard that sound before. Its really loud. You can hear it on the track and its disruptive. Im going to have to get a different servo. Cant say new one cuz this one is new.

Sounds like it might have a chip on a few teeth. SPMSP1046 is the whole set of replacement gears. SPM9063 is a Metal top plate replacement, good upgrade option. PM me is you have any more questions.
