I dont know if its a legit site but you can download RF demo looks and flys like the real thing. I think its an Italian web site I did download and run it prior to purchasing RF it ran perfectly Phoenix also provides a demo. To run RF. you will need an older copy of Windows direct x if you research the fix you should be able to run RF demo. When i ran the demo it asked for the older copy of dx i asked RF on the phone about the demo they looked at the web site they werent aware of the demo but said it looked Italian. I virus checked it and it came up ok. Since then i have a full version of RF 7.5 running on my win 7 computer also have 4 gigs ram. And deleated the demos. RF stated that if i couldnt get it to run it would be ok to sell it just unregester the copy from my computer first.
