    Hey guys,

    Wondering if someone could help me with this.

    I am getting what looks to be like a wobble in my picture - its noticeable in the corners of the video, not so much in the center.

    My setup is the Cinestar X8 with 450mm booms carrying the Movi M5 with the MR kit.

    What I am thinking is the rubber dampeners are bottoming out from the weight, or could it be gains or something? Anyone else had this issue?

    Thanks again,

    George

    Could you put up a sample video on Vimeo or YouTube and then post a link, please?

    Thanks
    Andy.

    Hi Andy,

    First of all thanks for getting back to me so quickly, sorry I have taken so long to get some footage up, just havent had the time to fly.

    Excuse the camera operation, was a friend of mine first time on the controls. And I know the Movi Gains could be increased, this was the auto calibration, any tricks to get this better?

    As i originally stated, it does look like the vibration isolator things in the bottom of the CS frame that are bouncing too much and hitting into themselves.

    Here is the link: http://youtu.be/ZLaAQ6DjrIQ

    Thank you for helping out!

    George

    George, do the auto calibration while in the operating mode, not in the stand. If two hand carry try doing it with the carrier holding the MoVI as still as possible. Might get you some higher gains.

    In addition to Gary's advice (and he's correct), try just hand holding the copter on the ground and simulating "flight" -- especially, yawing left/right and or rolling left/right -- just to see if you can observe/feel whether the vibration isolators are indeed limiting out and banging against the carbon fiber?

    I suspect, from watching the video, that the issue is just the MōVI gains....but that's pure speculation on my part.

    Andy.

    Thanks guys, so am I right in saying I should have the chopper suspended in the air on a stand or between chairs and then calibrate?

    Thanks,

    George

    That's correct, George -- you need to create the situation in which you're going to be using the MōVI.

    So it seems when I shake the chopper left and right that the carbon plates do bang. I will try and get higher gains on the Cinestar to reduce this for one.

    But does everyone run the standard cinestar 8 dampeners on their movi's?

    Thanks again

    Did you find any solution to this? I have similar problems.

    I am running the A7s now and problem seems to have disappeared, may have been the dampers
