The Meljet model that AAce suggested is wonderful. I'll give you a quick tutorial on how to add a texture, it's really not hard. All the hard work has been done.
This is a normal entry in an aircraft.cfg file (a Project Open Sky AA
[fltsim.1]----------------------------------------the number should be the next available number. The first entry should be 0
title=Project Opensky Boeing 757-2Q8 AA
Modern------if you've got multiple repaints, the title needs to be different for each one. You could just add a 1 at the very end, and it'd work. This ensures it'll show up in your Select an Aircraft menu option
sim=B757-200-RR-RB211-535E4------don't worry about this, this refers to the .air file you'll see in the aircraft's folder
model=---------------if you've got multiple model folders, the extension of the correct folder. For example, I have a wingletted 757 in the same folder (my main folder is American 757-223 POSKY), and the folder for that model is "model.w." If I wanted the wingletted model (make sure the repaint is a wingletted repaint), i would put "w" (no quotes) next to the equals sign.
panel=------just as with the model section, if you've got multiple panels, the extension of the panel folder goes here
sound=RR---------same with model and panel folders. In this example, I have a sound.RR folder.
texture=American-------------Ok, when you download a new repaint, unzip, and save the folder with all the .bmp files as a texture.xxx, with 'xxx' being whatever you want it to be IN THE MAIN AIRCRAFT DIRECTORY (the one with model, panel, sound folders, .air file, and the aircraft.cfg file). In my case, I have a texture folder that is texture.American. It's really that simple.
kb_checklists=------IINM, this directs FS9 to the kneeboard checklists file (You know, the one that you press F10 to pull up). I think this will be a .txt file.
kb_reference=------this is the reference file in the kneeboard, format should be the same as the checklist
---------Everything below this line refers to in game things, not folder things
atc_airline=American-----------This is the callsign your aicraft will have from ATC. The list can be found in the section of the Select an Aircraft page where you edit your Registration number (N-number)
atc_flight_number=2167--------------ditto, except flight number
ui_manufacturer=American Airlines------The following three things all relate to two things. 1)The location in which you find the plane on the Select an Aircraft menu, and 2)What is displayed on the scrolling ID tags in game (the red ones). This menu option determines the Manufacturer (the first dropdown menu). I like to organize my planes by airline, not Manufacturer, hence the "American Airlines." Default options for FS9 are Any, Boeing, Cessna, Extra, Learjet, etc... (just you know which dropdown I'm talking about.
ui_type=757-200------This menu option refers to the 2nd drop down menu. As I said before, I have it organized by airline, then aircraft, so this one is 757-200. An example of a default airplane would be like Boeing->747-400.
ui_variation=American modern-----This identifies the paint scheme, and the 3rd dropdown menu.They're all neatly headed according to this file. The first menu is Manufacturer, the 2nd is Type, and the 3rd is Variation. The default 747 for Global Freightways can be found like so: Boeing->747-400->Global Freightways. I have American modern since I also have an Astrojet repaint.
description=Model by Project Opensky (www.projectopensky.com). "1959 Astrojet" color scheme (Textures) by David Gutierrez (Cuauhtli Studios)---------what shows up in the 'Description' text block.
atc_heavy=0---------0 means ATC will not append "Heavy" to the end of the callsign, 1 will.
atc_parking_types=GATE---------If this was an AI aircraft, it would direct it to the correct type of parking space. Parking spaces can be edited using Lee Swordy's AFCAD.
------Parking codes for AI aircraft. AI aircraft can be directed to a certain set of gates by editing the parking code in AFCAD (doesn't always work, though).
Sorry if any of this was just too obvious. I wasn't meaning to insult your intelligence, just wanted to make sure you followed me.
Let me know if you have any other questions.
