I agree with NovaBill. I have RealFlight Deluxe and have no desire to upgrade to G2. Yuo can pick up a 2nd hand copy of RF Deluxe for much less than you'll pay for G2.
The flight characteristics are very convincing and I have no doubt that a person could become ready to fly solo by practicing on the sim. However, I still highly recommend having an experienced and capable pilot take your first plane up and bring it down for you. Most people who buy a plane and try to fly it without help crash their plane often enough that they get frustrated and quit the hobby. Anybody can get it off the ground, its getting it back down it one piece that's the hard part. Join your local club and have someone teach you.
