Ah-yup. Bob's got it- it can't do what those games do, because it's not built in the same way. Even the small degree of it there is (the whole inertia thing) is simulated. If you can substitute one set of table data for another by puching a button, you might have a way, and if you figure out a way to do that, all power to you- that'd be one of the coolest source edits ever. But you can't just sit down, reengineer the whole flight engine, and plunk it out in a week, centered around a new modification. If there was some glaring problem, then I could see someone attempting it, or if everyone wanted a completely different mode of gameplay, but to fix some little thing like this, which can be done in several ways already in the game...
