From what I've found, the planes on RealFlight fly just like the "real thing". I've found that you can adjust the CG, wing chord, etc on the plane to make it handle differently. Move the CG too much..... and whoops! The plane is uncontrollable, just like in real life.
The nice thing is.... if you crash, just hit the space bar. The plane is good as new, sittting on the runway, ready to go!
( Wish it was that way in real life too! )
Hope this helped you.
Best regards,
Mike
