Hi, I crashed my P2 from approximately 60 foot. The battery died towards the end of a flight. It hit so hard it knocked several components off the main board. I started by replacing the main board. However once powered up it just beeps Motor 1 and Motor 2 flash red lights Motor 3 and Motor 4 flash green then yellow then no flashing the beeping gets faster and more erratic. I then proceeded to the flight controller, removed it from the board and shore enough there where components rattling around inside of it. So today I got a new flight controller installed thinking this would get me up and running. Despite all of this, upon power up the beeping and light flashing still persists. I'm at a loss. Is there anything I may be missing???
