I think Reflex XTR rocks the house.... I thought it had much better physics than AFP Pro (though I haven't flown Deluxe yet) and it simply blows away G3.... not even a comparison.
I just added yet another video to my little "fan site" an indoor flight that looks like a real video... not only does it fly real, it looks so real tht it is almost as rewarding as flying the real thing. I don't get bored with it like I did with RFG2, G3 and AFP...
It's just like being there flying a real plane... I just can't put it anymore succinctly than that.
