Without a .bin log file no one can help you.

Please post that so that we can help you
And ALWAYS post the firmware version you are using.

Start with the VTOL Quick Tune script, then when everything is working well enough move onto Q_Autotune.

github.com

ArduPilot/ardupilot/blob/master/libraries/AP_Scripting/applets/VTOL-quicktune.md

# VTOL QuickTune

This script implements a fast VTOL tuning system for multicopters and
quadplanes. This script can be used to automate the process of
producing a good "manual tune" for the VTOL rate control parameters.

The script is designed to be used in QLOITER mode for quadplanes or
LOITER mode in multicopters, although it can also be used in other
VTOL modes.

# Parameters

The script adds 7 parameters to control it's behaviour. The parameters
are:

## QUIK_ENABLE

this must be set to 1 to enable the script

## QUIK_RC_FUNC
