Create your lua file

• Create your *.lua file in folder Scripts\DCS-BIOS\lib\modules\aircraft_modules\.
• Open up an existing lua and use it as an example.

Header

We will use P-51D as an example :

• P-51D is the DCS-BIOS Module Name, also the file name.
• The 0x5000 is the base address for this module, this must not collide with other modules
• "P-51D", "TF-51D", "P-51D-30-NA" These are Digital Combat Simulator's identifiers for the airplanes. In this case they are variants of the P-51D. By keeping them all in the P-51D.lua the DCS-BIOS module is easier to maintain. Usually there is only the one entry.
• P_51D is the local lua object name.

Footer

The file must return the local lua object in the end of the file as such :

return P_51D

Anything in Header and Footer

That is where you add your controls, digging into DCS files, using ModelViewer2.exe and test, test, test. It takes times and no two DCS modules are the same.
