I had just installed some freshly balanced carbon fiber props (1 prop was slightly vibrating) and then I flew my Phantom 2 about half a mile away and then decided to bring it back using RTH/Failsafe. The Phantom hovered over a tree instead of my take off area. In a panic, I switched from Fail-safe mode to GPS mode, then it started to descend rapidly with some resistance. After the crash I have a damaged GoPro, Bent Gimble, scratched GoPro, and bent/cracked DJI Phantom arm. Upon opening the unit I noticed one of the ESCs is cracked in half. I attempted to power on the Phantom and the LEDs flash for a second without the audible tone and then the LEDs power off immediately. The battery was at 82% level before it went down and the motors were still powered as I heard n the way down. I'm going to replace the ESC board but does anyone know if I might have other un-seeable damage which might prevent a proper power-on?
