    There's an A/V cable that comes in the box with the 5D Mark III. Use the yellow plug. :)

    Oh, he said, faintly, "That one?"
    I thought it was some other special cable! :)

    Hi Pavlos,

    Only the tape I find that a bit risky with all the cables pushing and pulling the Radian's, if one get loose...............

    Vibes? what is that ;)

    Hej Mario.

    For perfection, go get the dual bearing on the right tilt arm.
    I have it on both my 360 gimbals and it makes the tilt even smoother :)
    For heavy cameras it is a must I think!

    what gains do you achieve on the pan axis with the cx760 on it?
    if i go higher than 50% the gimbal starts to oscillate.

    Hi.

    We did some first tests today. But the result looked not that good.
    First part is inside and already here you can notice some vibration.
    It was windy outside and you can clearly see the vibration. It seems like the wind catches the gimbal. Also if i tap on the gimbal it oscillates a bit.
    But not because of the radian gains. the red dampers let the gimbal oscillate. If i remember me correctly we only.have 3 of them installed. It's not me who assembled it. Therefore i am not sure. Have to check that.

    Boss stabilization on the cx730 was set to off.



    at 1:30 it's stabilization only. no gimbal movement.

    Put the radians off and fly again to check it..! it seems that there is some vibe an overcorrection of Radians..!

    And the gain of the Controller seems a little high.>!

    we put off the radians and we still got vibration. i also have to say that it is very cold here. -10 degrees.

    The RVS wiredampers we use have no temp limitations, they work from extreme hot to extreme cold without adjusting ;)
