I was doing some inverted, waiting for my dad to take a picture of my BL while inverted... then the worst thing happened: The transmitter started telling me that the battery was low!!!! I figured, "well I got a minute while dad takes a pic"
Well, his phone was out of memory so he had to delete something... when he did though, it still said it was out of memory... so he sat there, trying to fix it, all the while the transmitter was sitting there beeping like a truck driver!
Finally he got enough space, and he was just about to take the picture, literally his finger was right over the button waiting for the right moment, then the TX gave up, letting go of the helicopter, letting it smash into the ground, inverted... *facepalm*
Luckily no damage suffered... other than my pride.
