Basin-- Some guys have done alot of research and do have valuable knowledge from reading, listening and watching.

Foxx-- I can comment, I have both AFP and Real flight. They BOTH HAVE some strong points. I do believe that AFP has an edge in the 3-D realm on planes. You can make a plane in RF to come close but not as close to AFP.
Now AFP uses the older technology to connect to your computer(no usb,firewire), so I feel RF has the compatibility with more newer computers via contoller connections.
They both will give your fingers and brain training needed to try manuvers without trashing your flyer. Either works well but again the AFP has the edge in 3-D.
