i'm just in the process of uploading to http://www.flightsim.com
an updated zip file of the above with a different solution to the aircraft.cfg especially with regards to SSTSim's version.
As you probably know,if you modify the aircraft.cfg and load FS 2004 and then load FDC,you had to reload SSTSim and start FDC again to get it to work as you got the usual flaps message,well after some testing i've found a way to tell aircraft.cfg not to rebuild itself as i couldn't modify the cab file...basically wouldn't allow me to.
I'll be uploading examples of my aircraft.cfg's showing what to modify and what it should look like.
Edit: Now uploaded to www.flightsim.com,just copy all files from relevant folders in zip to the same in FDC and overwrite,please see the readme for updated info.
