Servo noise
 

hoping someone can help me - I am getting a loud noise from the 7965MG once Iturn the transmitter on.
I have it hooked up to the following
Spektrum DX3r pro
SR3100 receiver
IP 3800 35C lipo
Hobbywing Xtreme ESC and Tekin RS Pro
Basically it doesn't matter whether I turn the ESC or Transmitter first the noise is there
Pm with help please

Don't know if this means anything but if I untighten the screw from the servo saver the the buzzing decreases to only when it's under load. So wondering if something too tight in servo? Because I'm not sure it's wise to drive with the servo saver screw untightened.
