    So I'm trying multiple low cost remedies to help get rid of a slight vibration effect in my gimbal. (not jelly, but vibration).

    Can anyone recommend a soft rubber damper? I currently have ARRIS dampers and they are pretty stiff and well made. But I think I need a bit more give in the damper to help absorb the rest of that vibration.

    Moongel muting pads for drums, works better than anything for the price, guaranteed.

    Your vibrations may be caused by wrong PID settings. You might want to dial your settings back. If you tap the camera with a finger and you can induce vibrations that way, it's your PIDs that are off :)

    My walkera gimbal doesnt use software. It's manual adjustments (and I tried adjusting those)

    I'm guessing you have the Walkera G-2D Aluminium Alloy CNC 2 Axis Brushless Camera Gimbal Complete Set for Gopro Hero3 PTZ?
    The CG (center of gravity) on that model is putting uneven stress on the dampeners, as far as I can judge from the pictures alone. Mainly compression on the rear and mainly pull on the front. The rear dampeners act as the rotation point. Try adding additonal dampening to the rear behind the rear dampeners? As a PoC, insert a piece of foam between the rear of the gimbal and the phantom fuselage.

    Well, believe it or not, the gimbal died.
    The vibrations could have been a result of the motors starting to fail or something.

    The gimbal was perfect when I first got it. But I ordered a new one. So we shall see

    Ok, that sucks :-(

    Since it is broken anyway, could you be bothered to take it apart at photograph the parts? I am dying to know what hardware they used, and if maybe the motors or controller board could be recycled :)

    are you looking for anything in particular? There isnt much - if any - labeling on the gimbal. And the controller is encased in plastic.

    I was looking for dimensions of the motors, connectors and possibly labeling along with weight. Also the layout of the controller and hidden access ports for software calibration.

    take a look here (from their website)
    http://www.walkera.com/en/admin/js/kind ... /20140123/

    tbh, the pictures I take wont be any better than these.
    And it looks like they give you dimensions, pictures of the motors and some ports.

    this short video helps too
