I got an RX LOSS and crashed into a swampy area of the field. I believe the aux 5v regulator shutdown (used for the Rx and the auxiliary items such as LEDS) The microcontroller has its own regulator. Upon closer examination I found the 5v lead for one of the LED strips had broken from the board and believe it may have shorted the gnd/5v pads for the LED strip, and caused the Rx to lose power as well. About half of the FC and ESC ended up getting wet, and things went from bad to worse.
