WOW. This phantom prop issue has morphed from a single video with no flight data to unsupported speculation to a class action suit against DJI. Lots 'o drama.
That drone replacement doesn't indicate a widespread problem or a lawsuit in the...
What other quality issues are part of that overall decline?
Has the incident described by the OP been positively attributed to an in-flight prop failure?
All the symptoms of uninformed people making guesses regarding the cause of the incident.
I emailed the video guy a week ago asking if he could share the flight data to help find the cause of the incident but he hasn't bothered to reply.
