My point is just that if he had let go of the sticks, that model would have crashed. It was only "flyable" because he significantly altered the trim to adjust for the new CG. Even then, it required constant attention. I trust he got it down immediately... I don't think he flew it around that way for fun.

We are coming from different angles... I want a model to be neutrally stable, if not slightly positive, while you are happy with divergent behavior. CG position, along with the associated trim, is largely what determines which condition you have so, in my mind, CG is important.
