I just set up my AFP and have been practicing on it and i have to say that it is a good sim compared to FMS and the model i was flying was fairly close to how my UCD flies which is what i was looking for...there's nothing wrong with FMS considering it's free and it did help me understand how the plane is going to react when it was coming towards me..it's not good for 3D but it is good to learn on if 3D isn't what you're looking for.
