FMS will do the job. If you're just looking to learn orientation etc, it's great. Beware, though, if you have VISTA. You will need to insert a .dll file into your windows directory, and you will have to turn the texture off, which more or less makes the program look like complete crap. The planes look fine, but the background is basically green and blocky. If you are working from XP, everything should work well. You wont find a better FREE sim.
