I Looked into the logs, but there is not really much that points to a problem. The flight log just stops at the moment of impact which is probably 7:25:50. At the same time the ESC delivers a overcurrent which is probably the motor being stopped by impact.
Before this event, nothing special is being logged. Radio log is super clean, not issues here, RX voltage looks good, no surges etc.
So my guess is, that the rotor lost drive, but the motor still spins. So maybe a failure somwhere in between like gear, freewheel hub, jesus bolt etc.
so long ... Uli
