RE: Getting in to IMAC
There is no doubt that bigger flies better. However, if you are just starting in IMAC, I would be real careful about buying a big, expensive airplane. What you need - more than anything else - is something dependable that you can put LOTS of flights on. You will find yourself in uncomfortable situations time and again, and when the big $$ are staring you in the face, things can be REALLY uncomfortable. I flew my first year in Sportsman with a 50cc Edge. While it wasn't the best plane at the field (I routinely competed against 35 and 40% airplanes), it was a fantastic plane to learn the skills of flying precisely. The year before - right before my first contest in Basic - I trashed my Goldberg Ultimate. Got disoriented flying BASIC. Laugh if you will, but this stuff is hard when you are getting started.
I am now flying a 40% plane in Unlimited and have for the past 3 years. It is a great flying airplane. But honestly it isn't needed to learn the basics. If I could have afforded it, I would have owned one sooner. But I probably would have been scared out of my mind flying my first unknown with it.
Whatever you choose, get out there and give it a try. I can almost guarantee you will enjoy yourself and find your skills improving every day.
