    What happened here? Drone never crashed is healthy.
    Only thing new i did today was a sun lense cap and new gimbal guard attached. Nothing else. It flew fine in overall but did this.

    you might need to balance the camera with some weights, or scrap the sun hood as it might cause too much stress on your gimbal motors as is.

    I have a sun shade and never fitted it. Looked to me that it would put to much stress on thing for not much gain. Got a set of ND filters instead.

    You could try balancing it like the people with rainbowers filter kit do

    Personaly i didn't like it cause it BARELY fits the camera. It very stressfull to put it on.
    So i prefer to work without it.

    So you guys think the thing in the video is lens cap fault??

    Fly without it and if the problem doesn't occur you have your answer.

    Its only 2 grams. Do you think that really could be the reason?

    Yes and nothing happened. It just surprises me how can barely 2 gram thing cause such thing?

    I've a friend had a similar problem, looked like the lens cover was catching or rubbing on the gimbal guard.

    It depends how far a weight is positioned from the fulcrum (the center of the axis motor.) 2g can be multiplied by distance. 2g positioned 2.5cm away would need to be counter balanced by 4g positioned 1.25 cm away on the opposite side. (Back of camera axis) I don't know the exact lengths here,,,just trying to go by memory, but powered off, the thing is well balanced. Add weigh opposite the camera lens until the camera can be placed at any angle (powered off) and doesn't move when you let go. Double sided tape,,,penny, nickel, quarter?

    I wonder if prop wash or some other gust of wind could put more stress than just the 2g.

    Btw: this should not be called a "cap". A cap completely covers a lens. This is best called a lens hood, regardless of what the mfg calls it.

    At any rate, it almost looks to me as if the lens hood hit the newly-mounted gimbal guard.

    Edit: added "not".

    I bet you are exactly right
