PPL152, mind that *any* aircraft has certain limitations and *any* aircraft can fly manouvres that can be consided aerobatics within these limitations. A wingover, as an example, is generally considered an aerobatics manouvre, but it should be flyable in any aircraft from a C-150 to a B-747 because the g forces involved are very low. Although I admit you would not stand a chance, not even in the "Beginners" class if you try to fly aerobatics as a competition sport in a C-172 or a B-747. But my point is, if you look around, there should be a few aircraft in your area in which you can fly a few basic aerobatic manouvres. The line between a non-aerobatic aircraft and an aerobatic aircraft is very fuzzy and some aerobatics-capable machines are surprisingly good tourers or trainers as well, so you might not recognise them readily as aerobatics machines.
I, for one, was very surprised to see that the kit-build Europa was able to do most standard aerobatic manouvres, including rolls, loops, stall turns and such.
Also, I have not seen it yet in this thread, but did you buy David Robson's "Aerobatics Principles and Practice" book? Great introduction to aerobatics.
