You may already know this, but I couldn't find it in a different thread. I've found two small glitches on the f-18 model.
First, when I bring up the default livery, I don't have a HUD displayed. The HUD loads when I change liveries, and when I return to the original livery, the HUD then appears and remains there throughout that session. Restarting the program resets the issue.
I'm having some trouble with the NWS/NWS HI features. When the model first starts, you get NWS HI which is great when you taxi around the airport. Once you achieve a certain speed or take off, NWS becomes the default (great for landing, lousy at tight ground turns), and nothing short of changing the livery will reset it.
I hope this helps.
By the way, I'm totally addicted. I can't go back to 2-D, and as much as I like other simulators, you folks have found the perfect combination of fluid movement, eye-catching graphics, and flight physics that make me want to use the program way too often! If there's anything I can do to help, just let me know.
