    I hope my description is accurate.
    Where the top of the Yaw Arm connects, there's a set screw that tightens on a flat sided shaft, which I believe is the Yaw motor shaft.
    Anyway, there is some play or wiggle at that point.
    I noticed my gimbal shaking last week (a day or so prior to a crash) while hovering at eye level, which I thought seemed odd.
    Now I'm replacing the gimbal ribbon cable, and notice what looks to me like an abnormal amount of play. Wondering if this looks abnormal to anyone else.

    Does it wiggle like that once the cover is back on?

    Think once the set screw is in, there should not be any wiggle :)

    Yes, I actually noticed the wiggle before disassembly

    Let's say the set screw is at 12 o'clock, the wobble is from 9 to 3.
    I can agree that tightening the set screw may reduce the wobble, I would think that from the factory, the Yaw Arm would slide on the shaft with very little play....less that what my video shows.
    The set screw wasn't even very tight. I didn't have the correct size allen wrench, and was able to loosen the set screw with an Allen wrench slightly larger than the set screw.
    I may try to shim this a little.

    You may want to get some threadlock and apply it to the screw as well to hold it in place.
