There is such a huge difference in the reynolds number between our planes and the full scale planes along with wing loading that it is impossible for our planes to pitch like the full scale planes do before a snap and still come out on anywhere close to a straight line. With that being said, ours can still most definately break the nose and autorotate, just not to the same extreme.

If you get a chance watch some full scale videos and see how far the plane pitches before a snap and then try the same thing with one of our 35 - 40% planes. The plane won't stall with a pitch of the nose, it will just start climbing.

I'll try and find some links and post them on here later.
