Hello everyone.  
I have a backup of my parameters in the px4 version 1.10.1 where the multicopter flies fantastic. Now I have updated the firmware to 1.11.2 and loaded these parameters, but the multicopter completely loses stability and control, only in takeoff it already crashes. Is there a way to make these parameters compatible? I wasted many days fine-tuning the entire setup and would not want to start over.  
Thanks
