PID parameters change after motor+prop change

Thank You!
I have checked vibration levels: they are pretty low, but I can’t recall numbers…
With default PID values the drone was oscillating, I had to lower those values by 50%, as per documentation.
So if Quicktune sets values around those valurs (or higher) then I need to re-perform Quicktune flight, because there was not enough wind for proper Quicktune.

Do I understand correctly?

I had chance to perform the Quicktune. It worked! I was able to save the results, thank you @amilcarlucas
After quicktune did a little bit of test flying for MAGfit. I haven’t used madfit LUA script yet, maybe next time I’ll try out.

The quadcopter wobbles a little bit while hovering. I haven’t done autotune yet.
As far as I understand, AutoTune tunes the copter to almost it’s maximum capabilities.
It should improve this behaviour, shouldn’t it?

No need to multiple post this as a new issue. Continue it here.

I did all the mandatory steps in Ardupilot Merhodic Configurator, until Autotune (including Autotune), then executed step 53, the final step.

The copter flies, I haven’t seen in the logs and during flight any oscillation.
However there is a little bit of shaking/wobbling during hover in a windfree testflight.

Can I somehow fix it with more gyro filtering or with better FC insulation?
Or is this the maximum that a drone like this can do? I can accept it, I just don’t know yet what are the capabilities
Will this behaviour change if I mount the payload, that is about 800gramms?

Copter details:

  • FC: Micoair H743
  • Battery: 4s2p 4000mAh
  • Motors: 2306 2450kv
  • Prop: 5.1x4.5 inch
  • GPS mounted on a huge standoff to avoid interference with magnetic fields.
