Can anyone tell me if these PID’s at the very end of this page
copter.ardupilot.com/wiki/dji-f330-flamewheel/
are also good for 3.2 for a stock flamewheel 450?
those gains are a good baseline for the f330. your 450 will be much heavier so you will need to tune your gains for your aircraft and flight style.
you gain use those gains as a starting point and manually tune (fly, change tune, land, repeat) or you could give autotune a shot.
