Good day. I am new on this forum. I crashed my P2 V+ (V1) at the end of last year. I am now rebuilding my phantom in several steps. I have come very far but the last step is keeping me awake at nights. It would be fantastic if one of you veterans can give me a golden hint. Let me give you as short as possible the steps I took. Phantom crashed against building with one of the four rotors. It pulled back instead of levelling. No balance. Shell was dented, so one motor was not straight up anymore. So I took of the props. After the shock I started my Phantom carefully. At first there was a compass error and some problems with the led's But after the first attempt: - Full red led error. After opening up I observed the following: - motherboard was missing the compass connector and the tiny DJI battery cable that makes sure you use the DJI brand. They broke of by the crash - some led's broke of from one controller - one cable was torn in two I bought the following parts: - new motherboard - new cable - new controller (V1 version) - new shell After a very careful "operation" with all the new parts and with good soldering I connected the P2 to the PC assistant. No errors!!! I was very glad. I did a advanced calibration just to make sure. I also calibrated the transmitter first with rc assistent and later with assistent 2 in basic tab. All OK. On a wide field outside I did a GPS calibration. All led's fine and I did a test without the props. Everything worked!!! including gimble, cam and FPV. YES!! I did the first test without props. All looked great. Time for the real first fly test. Before ascending the P2 pulled to the backside in a second (the side of the crash) very strange squeeky sound when props came to a stop. Than I thought that there was still something wrong with one of the motors. (One of the motors were it hit the building had a small dent). - So new motor soldered on. But no difference at all. Still pulling to the side of the crash (to the backside) - 4 new props out of the plastic, no difference I do not know what to do anymore. Can someone please give my some new ideas? Thank you very much. I would really love to fly my P2 V+ again. Best regards.
