Hello to all
Can someone analyze why my X* crashed i suspect problem in compass and probably problem with internal compass
Hello Antkon
Besides your compass interference are high, I don’t think that was the cause. I would suspect that your PIDs aren’t adequate

By the logfile , in the last few seconds, starting on line 48.5K it looks like the copter has wobbled hard on roll axis then a brownout occurred. Did the batteries got ejected ?
How did you tune your PID parameters?
Also your vibration levels are pretty high. I don’t think that was the cause either, but it could bring you problems.
Could you describe what happened? Did you tape that?
please alla refer here
Looking quickly at the log, there are a lot of instances there the actual pitch is opposite to the Desired pitch.
This would indicate to me either the motor / prop setup is back to front or the AMP is facing the wrong way.
I will have a better look at the logs later…
