Can anyone help me, I’m using a HolyBro Pixhawk 4 with Mission Planner 1.3.66 and firmware 3.6.9, for the second time I have strange reactions on the flight, the first one seems to have entered Failsafe, 2 meters high and now flying with everything perfect came into CRASH shortly after a more closed turn falling without any explanation, escs and GPS were calibrated
I have tried to solve an EKF problem that turns red and only releases after some time that the GPS connects more than 5 satellites.
Other problem are the engines, I can not stabilize in the log, even using various calibration settings in Mission Planner, I have escs DYS ARIA 40A ESC 3-6S BLHeli_32 Dshot1200
I do not know if these problems may have occured the problem, I ask for help
Thanks
