where do you live?
I am an acro instructor in MA flying a super decathlon and an extra 300 and we have an aerobatics course that runs around 10 hours and the decathlon is 154/hr. After the course you have your tailwheel endorsement and are ready to compete in local contest in the primary category.
If after that you want more we do advanced all the way up to the unlimited category
for the basic course you will learn unusual attitude recovery
spins
loops
immelmans
hammerheads
half cubans
slow rolls
and a few other maneuvers thrown in there.
any questions let me know, there are great aerobatic schools everywhere and I would reccomend starting in something cheaper, maybe even a citabria because it will make you a better aerobatic pilot and save you money in the long run
