Every flight you make different modes appear and disappear. Make a simple hover flight in AltHold for 1 minute and use that to set the Notch Filter.
Doing this is pointless unless you are tuning the Pitch Rate:
And if you want to do that use In-flight/Transmitter based tuning. This assumes you would abandon Auto Tune.
And I have to agree with @Michail_Belov on the rigidity of the arm mounting. This kind of looks like an X-class frame so check-out how TBS does it with the Source X Frame.
Thank you. The distance between the bolts sticked with frame is 20mm x 15mm and bolts are near to the arms. As we did drop test and check the rigidity by physical inspection. It is rigid and no resonance created. But even though it is rigid but what making the tuning to give the poor gains.
I did a hovering flight ,analysed and applied filters then followed instructions. Did autotune at roll axis the angle i got is 3.4 where as in pitch axis 7.2. Filter worked well in pitch axis but not in roll. I will try to do one more autotune on roll axis and check whether it gives good value or not.
May I know which edition should i refer in feedback control book?
Newer editions are more up-to-date, but any edition is good
