Silverstoned, why do you think I never sent mine in. Mind you, I have the highest respect for your patience to send it in. A patience I don't have. DJI, I honestly feel, has been in denial of this issue. An issue helped by a few factors. First is bad pilots who crash a lot and subsequently relegate any cracks to the post crash damage department. Then there are owners completely ignorant of the fact that their phantoms, be they two or three, are cracking without them knowing it. They crack period. And they crack fast. Overtightened screws aren't the issue as much as shells which are way too thin at too stressed a part. When it is this sensitive to over tightened screws, why aren't any over the inner screw holes cracking when they are screwed by the same assembler at the factory??? Because the phantom has thicker plastic inner screw holes that's why. There is NO solution other than either finally a proper redesign addressing thickness of material at arm ends, or super gluing the shell. There is nothing else. I love everything about phantoms, including the form factor which I love. But the quality of the shells and resistance to stress is more than lacking and people need to A, inspect their craft. B, speak up.
