[My F550 crashed! My F550 crashed a while ago. I still haven't figured out what exactly happened... I'm guessing a ESC failed. The hexacopter became pretty much uncontrollable about 20sec after take-off.
It fell from the sky from about 40 meters. This is whats left of my F550 now.
To be honest, i don't even feel to bad about it :) its gone, time for a new multicopter.
I think I will fix this one, and put it up for sale when its done...]
