Best PID for big hexacopter drone

We made our first flight with PX4 some weeks ago with default PID.
We had a hard landing:

The drone was stable the first seconds, and then start oscillation.
I believe that the problem are the default PID.

Could someone recommend us a good PID configuration for our frame?

Here is the log:

Thanks!

It’s an iterative process so it would be best if you understood it.
