  • do not activate joystick before the gimbal is working. You need to read the users manual, perform balancing and basic setup and then PIS tuning correctly.
  • I get the same problem only when it's hooked up to the PWM pitch line from the UAV...
    without this line and using the GUI I don't get any jerking...
    and it's only on the pitch axis...
  • Sounds then you have a problem on the PWM channel. RC LPF filtering can help, but look for what is the original problem.
  • I did just that and it's working now... thanks...
    right now the pitch is slow moving but bearable...
    a bit more tweaking to do...
