Guys, I think this is what Snowdog was thinking when he started this thread. Great discussions so far.
To see what happens when you blend IMAC, Pattern and 3D flying I would offer watching a few videos of my friend Cody Wojcik. IMHO I feel he puts his precision background together beautifully with an uncanny 3 D ability and creativity. For Cody 3 D most certainly has lines and he/ we have been kicking around how to do a judged 3 D comp. where maneuvers would be "required" similar to a sequence. From Cody's foamies to 60" planes to giants at Unlimited IMAC and Freestyle you can tell he has a background in precision flying.
Yes, he is my motivation for getting better and more precise. Look him up on you tube. I'll go fetch an EF 60 Laser vid he did recently that shows my point.

I just call Cody's videos "something to shoot for!"
Also shows that a 60" electric is fine for a first go at Basic. Even smaller will work but you want to have enough battery to get through 2 sequences per round, about 3:30 per sequence. My 6s3300 will give about 7:30 - 8:00 flying iMac maneuvers.
