So today I had my first crash.  Flew for maybe 5 minutes and lost RC connection.  RTH kicked in and it came back but was landing maybe 10 feet from where it took off and was by a tree so I canceled RTH.  It was hovering maybe 12 feet off the ground and I could not get RC connection still. My RC was completely dead no matter what I did.  Even tried to reboot the RC.  The only thing I could do was wait till the battery died.  When it did it hit some leaves in the tree and came crashing down.  I caught it with my hands but it slipped out and crashed.  One of the rear feet came off but I was able to snap it back in.  The only visible permanent damage was a few scratches on the bottom skids by the bottom sensors. I did a test flight and seems to work ok although I did not do a thorough flight. My question is what should I do in a case like this.  How do you regain RC connection.  Was totally locked up.  Even the camera has no signal.
