Strange BehaviourNoticed on X7 pro

Hi,

yesterday when I was trying to do autotune after dynamic Notch filtering which resulted in a crash on MFE Fighter VTOL. I have noticed Some strange behaviour from X7 pro. While it was falling from the sky data was not logged also the memory card showed a corrupted file and only the last log which was renamed as 0001. Although I have other previous logs on the card which have vanished.

kindly help me out with this.

Attaching the last log as I don’t have previous ones Also someone helps me identify the reason for the crash. Is it purely due to z-axis vibrations or maybe motor input was low while it was tuning in the roll axis

Logs corruption Screenshot.

You Vcc (5 volts DC to the flight controller) is a bit noisy but doesn’t seem to be a major issue yet.
Apart from that, the problem seems to be that all power is lost, at least to the flight controller, and logging just ends abruptly.

Yes, that is obvious but what was the reason for the Power loss as the battery was intact and connected even after crashing. Seems strange.
