I have the latest versions of Aero Fly 5.7.7.1 on my iMac and Realflight 6.5 on my PC. To be honest, I liked my old AeroFly Deluxe Pro Deluxe much better. I thought the giant scale planes flew much better. I really liked the big Giles. The giant scale 3D planes in the newest version have a tendency to snap or drop a wing very easily. My actual SD models 33% doesn't do that. One of the moderators gave me some hints on modifying the lift curves for Airfoil Tip and Root as well as Attached Range and Stall Range to help reduce that tendency. You also need to reduce C10 to make the hump in the green lift curve smaller. That stuff all works, but I think the airplanes should fly like real giant scale 3D machines in the first place. My post was quickly deleted, but I was simply stating my experience with the program and my opinion.

The newest Realflight is pretty good, the giant scale Yak flies pretty well. There are not a lot of good jets in the program or the add-ons.

Simulators are good for getting started and for learning slow rolls, point rolls, harrier rolls, and hovering. At some point you will realize that the simulators do not fly exactly like the real models. In some cases they fly worse, sometimes a lot worse, and sometimes they fly better.

Simulators are useful tools, but don't expect too much out of them. At some point you need to get out and practice with the real thing.
