As of now, I have a 3d aircraft model complete with working textures. I also made a simple -set.xml file and a very simple 3D-model wrapper file by using the mini how-to that comes in the FlightGear documentation. I haven't added any repositioning or animation data yet as also described in the how-to, but the model loaded perfectly and I could select and view it in the aircraft selection list. By the way, you might know the aircraft I'm working on from a popular FPS called Halo. Anyway, I'm not really sure where to go from here. I tried running the sim with the banshee just to see what would happen, and I got the error "Could not open file E:/Program Files/FlightGear/data/Aircraft/Banshee/c172.xml" (not that I expected it to actually work with those 2 simple XML files). However, the mini how-to didn't seem to cover doing much past where I got besides repositioning and animation. Can someone point me in the right direction here? Thanks for any help.

Go to http://flightgear.org/Docs/fgfs-model-howto.html for a great tutorial covering most, if not all of your questions. Also, you can learn quite a bit from just glancing through the configuration files for the existing aircraft :)EDIT: Oops, Sorry, I just realized that I pointed you to the same page that's already in the Flightgear documentation :(. Well if you just want to see the model in FG, try running it with the ufo fdm. But if you actually want it to behave like a normal aircraft, you'll have to write an fdm for it. And I don't know of any tutorials about writing an fdm, but I'm sure they're out there somewhere. And, like I said earlier, it helps a lot just to look at the fdms for the existing aircraft.Does anyone know of any good tutorials for writing an fdm?
