Why don't you buy an RC airplane? A big one, that is. I have one but have flown it like 4 times. Its much better than what you are thinking about. Mine is like 4-4.5 feet long and is almost same in wing length. Google it on the internet and then you see that flying a big, light and fast remote control airplane is much better than making a computer simulation. I am an RC airplane enthusiast, have 3 planes myself. Every Sunday, at Bahira Town Phase 8 Rawalpindi, RC airplane enthusiasts gather and fly their planes. They are much elder than me but I am trying to learn how to fly RC planes like they do. They are complicated though but lots of fun when you get the hang of it! If you want the exact location of that RC planes flying place, here it is...
Enter in Bahira Phase 8. Ask people for "Eagle Chowk" and ask where are the people who fly those RC airplanes. Construction workers and guards would tell you. There would be some cars parked near the footpath, most likely what you are looking for. OR go to Saddar Rawalpindi. Go to that Chinese restaurant,"Chung Pa". It is opposite "Fantasies", the gift shop. Right next to the restaurant is an aero-modeling shop, "Fly and Spy". Guys there would be able to help you. Again, you should buy a RC plane which is much better than a simulation, my guarantee. Watch some videos regarding RC planes on the internet then you would come to know how much better a RC plane is than a computer simulation.
If you need any help, I may be able to help you.
