I have a RED Weapon balanced really good and when I perform auto tune, my pan motor stiffness always sets between 150-176, so as a result I hear a low buzz on the pan motor. Nothing load or crazy but definitely audible. I found it a little abnormal. I was told by a Freefly tech that I shouldn't be hearing anything from the motor it should be quiet. He stated the sound I'm hearing is from over tuning. But why is my Movi over tuning? Ive tried everything, Ive checked every screw, made sure nothing is loose and made sure the toad in the hole was secure and tight. I can here the low buzz even sitting a few feet away from my Movi. If i lower the stiffness down to 50 then the noise goes away, but I feel that setting is too low for my camera set up. Can someone offer input.
