To start off, the past few months I haven't flown it. The camera would act weird with glitches and sometimes I couldn't have control over the drone (Not in the sky). It got to the point where I couldn't even fly anymore, it was in a system error. So I just left it alone. Now to day I decided I would charge it up and everything worked....perfectly. Then, I was in a hover and the drone went straight back at a 90 degree angle and crashed into the dirt. Now the drone is in a system error, I can do a compass calibration and that's it, I can get the rotors running at all. Is this a firmware issue that caused the crash? A hardware issue? Any other people experiencing this problem? Can you link me to something that can help? Thank you for the help -Bowman
