I was out flying today (39degrees) and my JR8717 makes a chripping on the collective.
So I landing and bench tested and when I move the collective there's a chripping sound coming from one or more servos.

Anyone else experience this? Wonder what the sound could be?

They all work correctly with no glitching but make the chripping perodically.

Are you sure its the servos and not the swashplate on the mainshaft? Put a little oil on mainshaft where swash moves a up and down and see if it goes away. Just a thought.
