My MP2 controller had finally puked out. The micro USB female port o the side took one too many upsidedown attempted connections from the male micro USB plug. Of course, there's only one repair, and that is to replace the entire board that is integrated into the female USB. I bought the Mavik "Pro" part but when I looked inside my controller, I realized that it's not gonna work. I'm looking, but I can't seem to find the appropriate MP2 controller part. I've also talked with DJI support but now their site says they can't accept MP2 repairs, for lack of parts. Does anyone know where I can buy the part?
