Buttline,
Having in my past had the pleasure (if that's the correct word) of practising and performing limited aerobatics in the lynx heli I would advise you not to even think about it!! The accident always starts with "I wonder if" unless you are with a test pilot in a competent machine!!!!
Nick,
Do you know of, or remember a certain F. Zimmerman (think thats the correct name) who used to throw a BO105 around a few years ago - always thought that he was a guy with a death wish!
