About 2 weeks ago I got the Sunday morning off from family duties to go flying my P3 Pro for the first time in several months. Absolute treat until I had some sort of brain fade where on returning home I flew my P3 into a tree rather than away from it. This has never happened to me before in 3yrs of flying quads. I have never flown in headless mode, so have always been used to inverse controls on return legs. Damage included two snapped rotors, battery broke free of its compartment and the shell has a broken leg as well as multiple cracks on two arms. The shell will need to be replaced, which is fine. I have a spare for this sort of rainy day. What concerns me is that after powering back on I was able to connect, however the IMU was reporting as in need of calibration. I tried calibrating for a good 1~2hrs, and the process would not complete. Is there anything else I can do here to confirm what damage might have been done to my P3 systems? If worst comes to worst and I need to purchase a new P3 Pro unit. Is there anything I need to do to link the new quad to my existing controller?
