Great Post Andy (cereal poster)
There sure is some great designs there from around the world.
My design(s) are still just on paper ...I think I'm scared of success to be honest.
I remember when I was at the Crown Casino and making around $1,000 a day - it kinda freaked me out making so much money (especially when living in an old Dodge in a carpark on the Yarra), eventually I couldn't take the adrenalin and endorthine loading anymore and crashed out at the $10,000 mark after just two weeks.
I can say that my design is 'totally different' to those designs ...its almost as if the conventional fin design has always been structured by people who have been culturally grown by Aircraft/flight/etc and I know that the USA/UK has had its cultural strengths in these areas.
...anyway, I'm all just talk/theory at the moment.
