i have a question about PSC_ACCZ_I and PSC_ACCZ_P
is setting these parameters are necessary ?

what will happen if i don’t set them ?

and nother question is that my MOT_THST_HOVER is 0.26 and when i want to set PSC_ACCZ_P to 0.26 mission planner show a warning about out of range value
i checked docs it seems that minimum value is 0.5 should i ignore this warning ?

Hello Srs

Thanks a lot by your talk, also other people we can learn a bit.

Please, can you anyone to say me what say exactly this window? I asume that is not well wrote, can someone to explain ?

I have set already the size of my props in 9, but when I try to change this value to 12 because my props are 12, I save writing this in MP.

Then appear a little window

Saying :

Initial parameters successfully updated
Check parameters before flight.

After test fligth:
Set
ATC_THR_MIX_MAN to 0,5
Set
PSC_ACCZ_P to MOT_THST_HOVER
Set
PSC_ACCZ_I to 2*MOT_THST_HOVER

I misunderstand, because in the same window say that has been updated the parameters successfully ( I suppose the parameters shown after I change the prop value from 9 up to 12 )

But also say:
after test fly Set this 3 parameters to….
But only in the first one say to 0,5, but in the other 2 or 4 I’m not pretty sure… say nothing about a value….
