I recently upgraded to the G2 version of RealFlight. It was a good move. Much better for practice of 3D manuvers. A fellow club member has the "light" version and lost interest quickly. Just not a lot there. My suggestion would be for "G2". I really enjoy being able to download other plane set-ups from the RealFlight site and from other sources.
