It depends on what version you are looking for, I've got Microsoft Flight Simulator X Standard for about £21.50 off Amazon.
You can buy Microsoft Flight Simulator X at; Target, Wal-Mart, GameStop, GameCrazy, EB Games, and Best Buy to name a few, many other stores also sell it.

You only need a mouse and keyboard for Microsoft Flight Simulator, but a joystick makes it much easier.
Microsoft Flight Simulator 2004 retails for approximately $14. One may be able to purchase a used copy for less money than this via the Amazon Marketplace or via the eBay website.
Probably not because the main flight simulator in the world is Microsoft Flight Simulator. And unless Sony and Microsoft get together to make a flight simulator for PSP (which is highly unlikely), there basically isn't much ways for there to be a flight simulator for PSP either. There is a flight simulator for iPad made by some company but I don't think they're going to make one for PSP.
Because lots of power is much wow
The best is Elite Flight simulator, but this is a PRO product with a PRO price. All the software is purchased in modules, then comes the hardware, and a full setup will easily cost as much as US$10 000. For the rest of us, Microsoft's FSX (Flight Simulator 10), is about as realistic as it gets in all aspects except the price.
Yes, you can play Microsoft Flight Simulator without a joystick, you can play with just a mouse or keyboard, but a joystick makes it much easier.
Probably because of the graphics, go into Settings and lower the graphics.
U can download flight simulator from google earth or u can buy it for about $40 or u can get the gold adition for $60 FROM GOOGLE EARTH ITS FREE
Around 15 mill euro....
Microsoft Flight Simulator X says not enough memory because you don't have enough memory available. If you have other programs open, close them. If you don't you need to upgrade to more memory, buy another computer with more memory, or you can't play Microsoft Flight Simulator X.
An RC plane simulator would run you about $40.00 according to this site: http://www.trendtimes.com/rc-helicopter-flight-simulator.html You might want to do a search for yourself to see what you come up with.
