I still think in an ideal world all rec flying under 6ish seaters could be run with much reduced rules to commercial for the huge benefit of private aviation. I do think it is a bit of a shame that I can't take my kiddies and wife for a 'recreational' flight.
Having said that I don't believe that should be all up to RAA, in an ideal world the regulator would have it sorted.
Anyway I selected the 1500 mainly because I think extra numbers in RAA would be a good thing, the 750kg limit would be enough of a help to me to get me to 700 with my hornet but i don't want to be selfish in my thinking, also I would also like the CTA option.
