    Hello. I had a small crash yesterday. Everything seems perfect outside. No breaks, scratches etc.
    But there is a shaking video. Here is sample



    Any ideas how to fix this? Or service only?

    Turn it on, lift it up with your hands and study the gimbal too see where it`s potentially lagging or if you can see something else that is wrong. I guess it`s not the electronic, because of the physical crash.

    Maybe out of balance props.

    That would be my guess also. Try a new set of props first, or check your existing props for anything 'unusual' like nicks or even bugs. It doesn't take much to unbalance them. There are quick easy ways to check balance with a wine glass.. Check the threads to see how, or buy a proper balancer

    replace and/or inspect your shocks on your mount. (the white rubber things) You may have ripped one. I had the exact same issue.

    I'm suspecting that your gimbal has malfunctioned. Try doing a recalibration of your gimbal and see if it helps.

    Also tighten and check every single screw in or around the gimbal

    Ok. I think Ive figured out. Probably ist a fault of a yaw arm.
    When I power on and gimbal does start up calibration the yaw arm is not moving at all.
    I can move it manualy by my fingers but I have to put some foce to do that.
    So what next? :)

    Yep, it was that. Ive temporarily removed small plastic hood and it works like new. But what next? The arm doesnt look like bend or something. Is there any screw to loose it up?

    Where are you plastic antidrop clips at? The ones that diagonally sit on the shocks? I dont see one of them. Or are you missing both? You know what I'm talking about? The clear pins that goes through the white shocks?

    I removed them just for camera inspecting. Replaced also all rubber shock absorbers.

    Your arm may be bent. Looks like it took a hit. Someone else will have to chime in on the specs of a non-bent one. It could be as simple as bending it back in place, but I dont advocate that for liability purposes.

    Yes there is a set screw that will allow you to move the arm away from the cover

    Yes, you can loosen the set screw on the shaft that connects to the yaw arm and drop the yaw arm a bit lower to clear the obstruction.
