This goes without saying, but ok, just for the record, here it is anyway:

All maneuvers outside the 'normal' envelope of flying should be learned from, practised under supervision from, and then checked out for solo flight by an (experienced) aerobatics instructor! Some of these maneuvers look deceptively simple, yet are extremely dangerous without proper preparation and training!

Don't do this at home. Never, ever 'try out' anything !!
