This addon provides scripts to control the BF 109G-6 provided by FlyingIfron Simulations (payware). You need the Software Axis And Ohs (payware) to execute them.
This is no typical Addon to be installed into the Community folder. You need the software Axis And Ohs to import theses scripts and to map them to whatever hardware you are using. Unpack the archive file and use Axis And Ohs "Scripting | Import Scripts" to import these files. Your scripts will have a new group Bf109G6 containing all scripts.
If some levers or buttons are missing, just leave a comment. The screenshots will give hints on which element is controlled using which scripts.
