Best way to learn is to crash, learn how to crash properly.

That';s not always easy to do, if you have a sudden electrical problem, it';s going to bite the dust, happened to my mini hex  and bent the frame, snapping an arm, everything I tried to limit the damage was fruitless.
So I depends on whether you have control and just dumb thumb it or if it';s something more serious that causes the crash.
