Any explanation for a sudden flip in stable mode!? I was only hovering to test PID

I've crashed upside down :(((

The quad was 2 meters high and few meters away from me

Here's my configuration

DIYdrones arducopter kit,

latest ardupirates code,

X setup -apm pointing foward between F and R arm-

Turnigy 8ch radio

it seems so absurd!! Please help me, it's my second crash

Yeah, those bullet connectors have got to go!

I think the first and most import thing to look at are the power cables running to your motors. Look for and eliminate bullet connectors, loose wires, weak solder points and so on. In my experience, the two things that have caused sudden flips are bad power connections to motors or props breaking in mid-air (weakened due to a previous crash).

Are you still using the stock bullet connectors between the motors and ESC's? I had the same flipping crashes due to those crappy bullets. I've since removed them and soldered the wires directly together and have not had any problems since.
