    Hopefully someone can help shed new light on my pan shaking problem. During initial testing of the pan rotation with the gimbal suspended, I can see a big jerking movement of the pan at certain times. I've taken it up in the air, and saw that it does the same thing as shown in the video. I noticed that it happens when the CS8 is in motion and not at a hover. I have set my gain at 50, have gone down to 30, all with no luck. The shaking is towards the end of the video. All suggestions are welcomed.

    Hey Kristian,
    It's been awhile since I played with the pan radian. I've been flying solo with the 3-axis and have the pan radian unplugged, but I had the same problems as you when flying dually. I looked back at my notes and it looks like the following settings seemed to help, although still not perfect. Also I assume your camera is balanced on the pan axis?

    Pan Radian
    Gain 30
    Slew 20

    Ryan...your suggestion has proven legit during suspended testing!!! I've made my slew at 35, and gain at 30. Going to fly it in a little bit to see how it holds up. Thank you thank you!

    Pavlos, crazy that the gain has to be so low. Looks like a winner though so far! Thanks for the advice!

    It will be ok with low gain.. the only but think will be the stops..! you must not do Hard rudder stops :) you have to stop smoothly..!

    By hard rudder stops, you mean as the pilot? or for the operator?
