I have bought a new IFlight Nazgul Evoque F5D V2 HD 6S Deadcat.
I faced a common problem with Dji o3 vibrations after the footage stabilization.
The drone flew damn good.
The footage before stabilization process looked stable.
I had a discussion with Iflight support, and in the end they told me that the o3 camera has defect (I sent them BlackBox logs, footage).
They sent me back money for a second new dji o3 camera.
I replaced the camera but the problem still existed!
I tried everything to solve the issue:
- I have changed the ESC PWM frequency to 48Khz
- I tried to use a ton of other soft mounts designed & printed out by me (the result was better and better but still not perfect)
- I opened the camera and glued the lens (no improvement here)

Finally I did my own filters and PIDs tuning and I was surprised that the problem was solved at all!
So keep in mind that the tuning out of the box is not good, even if the drone flies good.
Your quad has to be PERFECT tuned if you would like to use Dji o3 camera. Soft mount is not the best solution at all.

At the end I'm using original soft mount from Iflight.
And yes, you have to set your ESC PWM frequency to 48Khz (fixed) - it is very important!!!
ESC PWM frequency set to 24kHz & by RPM is not good for Dji o3.
