The next thing after my tailwheel endorcement, I went looking for some aerobatic training. I found a guy with a decathlon that was more than glad to take me out and let me scare the crap out of myself. I loved it, and he sure taught me a lot. I will forever cherish it.
I'm really not sure spin training should be a part of the PPL for reasons mentioned. I do think all private, or at least commercial students should have some limited aerobatic training. Sure would be nice if flight schools would offer maybe a citabria for tailwheel transition and unusual attitude training. I owned a maule a few years afterwards, and one day I got myself into a situation where without that training, I would have busted my butt. So money well spent I say.
I LOVE TAIL DRAGGERS...MORE THAN THAT...I LOVE CROP DUSTERS...YAHOO!!!!
