If they (reflex) are depending upon the controller for realism I would forget reflex.
There is a new version due to be out soon for Reflex, it has totally realistic sceenery and aircraft images. Its flight charicteristics remain a question! Most people I no who have flow Aerofly would not part with the program. It appears to be that good in realistic flying qualities. This applies to 3d flying. . . I have realflight2 and it does not fly 3d right out of the box. It can be difficult to get to do 3d and have never seen a flat spin occur in realflight.
