I was hovering my quad at a fairly high altitude when it suddenly tumbled out of the sky into a 50' tree. I assembled a huge stick and got it down. I was flying while it was snowing... possibly a bad idea...I was about 2 minutes into the flight. I think the left front ESC failed. Bench testing now yields normal behavior from the other 3 motors and the left front goes "beep beep {pause} beep beep". I think this is a low-voltage warning. My pack is appropriately charged, I even tried 3s and 4s packs. Watch the video and turn on the sound, it makes kind of a grinding noise as it goes down.
Any ideas? Is this things fixable?
