Really cool link - but I don't consider any piro figures (piro circle and piro loop) "basic aerobatics"..

Maybe they are for some people, not for me though :) - basics I would say is loop, roll and flip (without the piros.)

That said, the link (and the followup one-tank-tips by nick maxwell) are really great and fun to watch, even if you're not yet at that level of flying (like me).
