Hi all. Whilst flying in light mist that very quickly became pretty thick fog I managed to crash into a tree. When I walked over I could hear a beeping that I assumed was because the compass wire had pulled out of the plug on the leg. After opening up the shell I've found that one of the 2 grey antennas has become detached from the circuit board, I can't see any other damage, I've been told that it's possible to fly with only one? Now, when I turn on the tx and connect the battery the nav lights flash but then all I get is the same beeping noise as initially after the crash. I've tried googling but all I'm finding is regarding beeping from the tx. Any suggestions please guys?
