Hype 3D and the Frenzy can do it. I call it a Toilet Bowl. I have never seen anyone do it before, or ever for that matter. My son, Airplane Zane (8) thought of it.

How's it done? It has more to do with the airplane instead of the pilot. Most planes will stall out and drop a wing or just go into some wild snapping motion.

I don't have vid I can upload, however on the Joe Nall edition of Inside R/C, they show me doing the toilet bowl with the Frenzy.
