Question about modding this.  I downloaded both the -100 and -200 and read the readme file.  There is an "installer" app and the proposed mods to the .cfg file.  When I click on the installer I get an error that it is corrupted.

So, is all I have to do modify the various files by hand?  There's nothing else?  I've never modded an aircraft before, so I'm a little nervous, although it looks to be easy, but tedious work.

Best.
