Thanks!
X-Plane allows one to create the aerodynamic shapes and wings of just about any shape aircraft, from flying wing to helicopter to wide body jumbo jet. It then will break that shape down into it's components and analyze them as you fly. It isn't perfect, but it's very close to a real time wind-tunnel. Therefore, what the flight simulation does is a close mathematical model of what the same aircraft shapes would do if they were built and flown in the real world.
X-Plane After you've created what I call the flight dynamics model, you can then overlay that with a more pleasing and accurate visual representation of the aircraft. Some flight models are pretty doggone good, but they lack fine detail. I'm a CG artist among my other skills, so I want my plane to look as real as I can get it. I've been evolving the design for quite some time, but anyone can make a simple plane in less than an hour. It's hella fun!!
