Epic flight ending with ESC catching fire

Had an epic flight today but it ended with an ESC catching fire and crashed high up in a tree. Lucky I managed to get it free with a long dead branche that was lying around. Probably a crash earlier that day caused some damage that my ESC went on fire during fast forward flight.
