FYI, I owned my P3P for 1.5 months before I noticed very slight shell cracks in the typical screw holes. I contacted DJI by phone and created a ticket. Yes I was on hold for quite a while to get through. DJI sent me a shipping label for free and I shipped it. Received 2-3 days later and I received an email stating it was received and warranty repairs approved. 7-8 day later, another email saying it's done and being shipped back. Received 2-3 days after. I give DJI 2 thumbs up for turn around time. Upon opening the box I found the repair on my P3P consisted of simply replacing the lower half of the shell. All else remained the same. A little surprised, I thought perhaps motors might be replaced with new design but not a big deal. I then took a light to the motor mounts to look for the new X-bracing and found none. Looks like the same shell again to me. What are the different versions of shell? Should I not have received the newer design X-brace shell? What is going to prevent shell cracks from occurring again?
