Hey Pete, as it looks like you are not getting any help, I talked to a colleague about your problem. He is a flight simulation engineer and is also working with X-Plane. He was the one who recommended X-Plane for my flight training preparation. I told him about the problem you have and he said you can contact him any time with respect to questions. He knows that it is tough going from classic simulation to planemaker, airfoilmaker and finally X-Plane, without knowing the details of X-Plane internals. Send me your e-mail address and I will get you in contact with him. Cheers, Steph
