I just bought the AK2000 and am actually quite satisfied so far. There is only one thing I could not find on the net: In the settings you should actually be able to enter the weight of the camera under "Payload Setting" or define the range of the weight. In all manuals and tutorials you can find the weight, here only "Auto-adapt", "Level 1-5" and "Custom 1-3", which are a mystery to me anyway. The result is that the gimbal (camera weight 1638g incl. lens) now starts to vibrate in certain positions. I have updated the firmware, but the display remains the same. Any ideas?
