Hello everyone,
I have recently crashed my drone and I'm trying to get to the bottom of it.
What could cause damege and breakage on tje back of a propeller, the trailing edge as seen on the photo?
Thank you all

Hard to say. Maybe a slow vertical descent over a tree or other obstacle and slight collision, before ascending again to avoid a worse impact?
