I have been flying my p3 professional for over 100 times. Took a lot of beautiful pictures and videos. Last Saturday took off with everything in optimal conditions, and about 3 minutes later a "No signal" message appears in my screen and my bird just fell from the sky. Camera broken (came apart). Very sad about it since I'm sure I did nothing wrong. P3 still turns on but of course I get a constant beep and I get a battery error message with all my 4 batteries. Any ideas about what happened? will DJI help me? Thanks
