Ouch.This DJI representative's response to our non-issue is rather interesting:

"I just turned my P3P upside down. I fly this thing all the time and I am not gentle with it. I have the braking set at factory defaults and it is tame compared to my Inspire. I have no cracks at all. I have to smile when I see users that have never flown their P3's and say they have cracks. I looked at their photographs and enlarge them. I will be honest, I don't see any cracks. I have seen some casting imperfections. DJI has stated that they will replace the shells if there are cracks in them. I am not denying that there have been some units with cracks around the screws. We don't know the exact cause and are still investigating. Understand, I can point to many more users that have stated no cracks vs those that are having the issue. I know of no other craft that users take out magnifying glasses to examine them."
Ken (blade strike) and Ed (Tahoe Ed) are great guys. Ken helped me get a new unit. But they both denied this is as big of an issue as you, everyone on the forums, and myself think it is. Denial I guess.
Ed is going to be touring DJI's new LA support facility in a few weeks. I told him to specifically ask to see my unit I sent back and tell me what he thinks. It's clearly a mold or some kind of manufacturing error.
Here is the first video I uploaded to YouTube last week. Read the comments. A lot of people have the same issue.
Here is a video of my new unit. No stress cracks, but definitely some kind of marks in the mold.
The problem is, is lot of people are not looking at the bottom of their units or don't know how to look for stress cracks. Share my video with fellow P3 pilots so they too can inspect their P3's. The more people that become educated on this issue, the more pilots re finding stress cracks.
