Carbon Falcon: Servo Humming Sound?

[PeteCress]

Sometimes I can hear a high-pitched humming sound from one or both servos (not sure whick).

I can make the sound stop by pushing a bit on one of the servo control arms.

Is this noemal, or might the plane be trying to tell me something?

Think this is normal servo chatter. We have a constant load on the servos, and they are a high torque but small servo. No worries.
