Okay so recently and I think always, My quad would just flip out and go down.
It seems totally random and not predictable, I can be hauling butt or just putting around and out of no where it will do a fast and hard flip to the back left.
I think it might be a desync but i'm not sure, I have some little bee 20A with BLheli coming.
SOLUTION:
The Serial connection was on a servo connector that had become loose and was dropping the connection which cause the fail safe to trigger... My fail safe was not setup up correctly.
