To me it's 3D. I love to watch/make the planes spin, twist and flop. What a rush. I'm not all that good but I improve every flight. I haven't really flown a pattern or other though. I do worry about the safety at the field. It appears to me with all the close in flying/hovering/tumbling moves that the potential for someone getting hurt is worse with 3D. I hope we can figure out a way to overcome the safety issue before it is mandated to us.
Thanks.
