high frequence jerkiness on YAW (and pitch)
  • Have Beholder EC1 and DS2-A.
    Perfectly tuned it (PID+filters+magnetic link.) but still have some kind of jerkiness of motors, most visible with long zooms...
    You can see how it looks here:

    Here is 800mm, shot handheld and you can see some low freq shake (hands) with high freq motors shake - that looks like rapid left-right pan in a fraction of time.
    How to avoid that jerkiness?
