I'm currently doing aerobatics as part of RAF Elementary Flight Training and it easily the best aspect of flying i have come across yet. I find i am much more accurate, co-ordinated and confident after just 5 hours of aerobatics tution
To back up Foxmoth's point i'm quite inexperianced, currently having 32 hours total time on the Tutor but i am cleared to do solo aerobatics.
Before we are cleared solo we are trained in spinning (entry and recovery) incipiant spinning, recovery from unusual positions then finally the aerobatics themselves.
Prior to being cleared solo we must demonstrate the above to a minimum of a safe standard. Then off you go!!!!
I would imagine any intro to aerobatics would cover the same areas so make sure you know how to do the above safely before you do aeros even if you have a PPL. (assuming these aren't covered in the PPL itself)
Enjoy the flying!!!
