I have the realflight, the field that i seem to like seems to me, the elevation is about 5900 feet. I didn't know that this effected (affected?) flight. I agree on the DVD coaster thing, you'll get more help from your sim than anything else... in my opinion.

don't take the simulator as being the same as the real thing, to me, it is very close, but not quite the same as in the front yard or whatever..
