I had a couple of months and maybe 30+ twenty-minute or less fun-filled flights with my P2 Plus with the Zenmuse H43D, a gift from my wonderful girlfriend, packed with iOSD, FPV, GoPro 3+ Black and a few other goodies to max out the capabilities of this wonderful surprise. So, about two months ago my fully "loaded with goodies" P2 with Zenmuse H43D and GoPro 3+ Black take off vertically at full power and uncontrollably after my doing the normal "Phantom Dance". At about 100' with no control, even when switching to Home, then NAZA mode, I decided to just kill the bird with full down and side deflections of the transmitter controls CSC? (new style 2 controller in case you were wondering). The bird came crashing down onto the roof of my steel building complex, which I am thankful for rather than hitting someone, someone's property, or a ski resort somewhere in the Rockies! So this became a work in progress, not aided to any significant degree with help from DJI or any kind of handy numerical reference as to what parts I was looking for. Damage to the shell was obvious, though I suppose I could have repaired the original that had metal screw fasteners pulled from inside their original mounts. So, I went ahead and ordered a new shell from BH Photo that came with new screws, but oddly enough, not the little rubber plug for the USB port. This was an original DJI packaged part. I took everything loose from the old shell and transplanted to the new, but now found that not only could I not power up from my controller, but Phantom Assistant informed me that I was not using the original DJI battery, which I most certainly was! I tried another of my three batteries to get the same response. I re-checked mounting of the battery connector to ensure that it was correct. I also noticed that one of the two receiver antenna shells was missing, so I tried removing the antennas from the receiver board only to find that they were bonded with an adhesive that proved impossible to remove. Bottom line, I broke one of the connectors off the receiver board. I ordered what I thought were replacement antennas, but they were for the P3 series, and I had broken off the surface-mount mating connector from my original receiver when trying to get the old antenna connectors off. So now I go and buy a new P2 receiver board that has the antennas attached. I was still getting the Assistant software message that I was not using original DJI batteries, but was hoping that at least I could get the motors to spool up. NO, no luck there. Then I found that one of my motors was damaged and binding to a stop as I tried to rotate it. I didn't notice this before, so I ordered a new pair of motors, one each of left and right rotation so that I would have a spare. I set the project aside for a couple of weeks, but was still thinking about the problems. I decided a week ago to do a Google search that defined my symptoms, and I found a YouTube video of a P2 main board replacement that pertained to EXACTLY my symptoms, especially the battery reporting one. I should add that Phantom Assistant showed me that the flight module and compass information was correct, and I am running the latest software. I went on eBay, bought a new main board WITH the flight controller and battery connectors intact, supposedly taken off a new and tested P2 (maybe someone else's crash?). Should arrive by the first of next week. Maybe my bird will fly again after all. I may not be terribly bright (No, I don't want to buy a P3!), but I'm awesomely persistent! May this little tale lead others into a bit of knowledge and enlightenment.
