I have a custom built F450 frame with a Pixhawk to which I have attached the famous great cheap Goodluckbuy gimbal (the 70$ one with Storm32 controller) and a Gopro Hero 4 Silver. I have done some PID tuning for the gimbal (well actually mostly took PIDs from others with the same gimbal and much more experience on some forums), but the video is still shaky and I guess it is from the PIDs, not anything that this gimbal cannot do from what I know.
Here is an example video I just took: https://www.youtube.com/watch?v=jDF1Jb-zMCY
I have also attached the PIDs that I am using for the gimbal.
Can you please give me any ideas on what to still work on? I don't have experience so I cannot tell if the shaking (mostly the vertical one) comes from a too low P maybe, or is overshoot from a too high P? Or shall I work on I and D some more?
