Agree, mine is flipping very easily in take off in man mode 1, and i always do fast climb to the air. When it's in the air it flies fine. Actually i take off always in gps or atti mode 2 as problem for me is only at mode 1, and my copter is balanced as perfectly it's possible. I think it is a kind of bug and should be listed to bug-list too.
