Sounds like they lacked abit of customer service skills.
I guess you didn't get any stick time or get to log the hour? Wouldn't mind a tiger moth entry in my log book.
Maybe they keep the aero's to a minimum to save the airframe, I guess next time go for a joyride in a pitts and really test your gutts out. There is even a guy in sydney that does Extra 300L flights.
Inverted spin anyone?
