Option 1: Be an adult - get in touch with DJI, be responsible and decent, tell them the truth and get ready to maybe spend some money and wait a while to get your aircraft back in good shape. It may take some time, may give some hassle, whatever... End of story, everyone wins and you're back to flying and filming again at some point soon.
Option 2: Be a warrior - you feel cheated and decide to cheat too, get pissed and join the unhappy crowd and it all spirals down. Fight for your rights. Just be warned: You'll come across other drones with their own issues and customer services too. The grass is always greener on the other side. Only it's not.
Option 3: Be a hobbyist - buy a new shell ($60, that's nothing in hobby terms...), get some tools, epoxy or whatever you feel works best. Hit Youtube, RC blogs & communities, take your time to learn a few stress-releasing skills (glueing, drilling, filing, coating, repairing, reinforcing, rebuilding, etc.) and be free, in total command of your P3 and the owner of your hobby - forever. Kinda like taking the Zen And The Art of Flying Phantoms approach.
There are other options too, of course. However you take it, you''l be much happier (and satisfied) if you accept this is not a vacuum cleaner, a TV set or just another "appliance". It's a highly advanced RC aircraft, lots going on with it. Lots can go wrong too. Fortunately it is also built in a way we can replace/repair pretty much anything for relatively little $$$ even the electronics which are usually a pain in many devices. And it works beautifully most of the time.
It is my belief we need to be patient with everything when dealing with drones in general, because it may look simple but flying these things demands a lot more than just cashing out, unboxing and charging batteries. From learning to fly and film decently and safely, to dealing with the makers and sellers, some dedication and time are required. Just like we also need to be patient with anti-drone crusaders, the haters and the admirers, the curious, the regulations, everything.
DJI is selling buckets of these because P3s are the best, they're also doing the best they can to please and support customers. But it can never be 100% smooth, there are a few issues for sure, and it's essentially impossible to please everyone so we will keep getting negative feedback regardless.
It is a FACT that no one knows for sure how many or what % of P3s cracking. Some are, maybe many are, it sucks to take the short straw and remain forcibly on the ground for a while, etc. But that's life. Take control.
