Hi. Today I had the first very bad crash of my Phantom Vision resulting with a bend and fractured arm. The battery and the camera were recovered near the phantom, and everything were reassembled. It power up normally, all the motors functioning like new, it takes 7+ satellites but... The only problem is that the leds under the bended arm stay off. What could this mean? A bad ESC? I ordered a new shell. Please give me any advice or diagnostic in relation to this. Thanks.
