My Moonlight kit died after a crash on its first flight. Was a pretty depressing. I eventually de-cased it out of boredom one night, to test for a short. I set it up again without the case, reseating the connectors, and it came good. Put it back together with some new thermal paste and it's been flawless ever since.
I deserved it.
