PID to start tuning a 900 multicopter

Hello,

We are trying to develop an airframe with the following config :

  • X frame
  • About 900 mm motor to motor
  • 12S 16Ah
  • Cube Orange
  • GPS Here 3
  • t-motor p60 170kv

And there is no way to find good PID setting to start the tuning.It could be aswell another issue.
Here is my last flight :
