I need to learn more about the differences in the simulators. I have been flying off and on for about 10 years, but have not tried a whole lot of aerobatics, but would like to try first on a good simulator. I am not into helicopters, and I don't need to learn how to fly trainers. I need to get the one that will help me learn rolling circles, spins, some 3 D. Can you tell me where to go to learn more. Which one is the most realistic. I had a Dave Brown but it was too basic. Thanks.

Try aerofly.de - best 3D sim in the market. You can get it from Hobby Lobby

Also give this one a try, you can also download a "Demo Version" to see if it will suit what you are looking for !!!
