    HELLO EVERYONE. Its been a long time since the last time i wrote a post.
    I have a problem. I bought all the parts for my cs8 and 3 axis gimbal. Its been 2 years and this thing has not flown yet. I have a very time consuming full time job.... but here it is... I the copter to stop the paning "twitch" , but then it starts to shake like a washing machine. I lowered the gain from 100 to 50 and still get that . The other radians "work" fairly, I mean They move "accordingly" not perfect but OK.
    Here is a video, help me please ! I also tighten the belt more.

    here is the link:
    the pass is : see

    The pan gain looks like it is still way too high, Ivan. Can you experiment with reducing it even more and see if that oscillation goes away?

    The other things to check are that the pan servo belt is tight (2mm of deflection when you press with your finger in the mid-point of the belt), and that the pulleys on the servo is tight. Any looseness in the system can make the oscillation worse.

    Andy.
