For a new AC to show up in free flight, the name of the aircraft on the AC folder and in the first line of the 'aircraft' file must match EXACTLY.
Tralfaz. This is not correct. The folder name & Aircraft.cfg title= name can be completely different & usually are. Aircraft.cfg does not need editing for the aircraft to display on the menu.
The main thing here is to make sure that the "aircraft container" folder is correctly installed. A very common problem is when it's hidden inside another folder. Please follow the instructions in this tute carefully.
