FSX New FDEs For BAe GR-7 Harrier. Config and .air file for Adam Preece's Harrier GR-7 (APDHARR7.ZIP). Mods to FS2004 files to work in FSX. See EZfly.txt for new and simple way to fly (flys itself). Only .cfg and .air files are needed; nothing else to install. The author only included the model and texture for 'clean', so you'll know not to overwrite your original cfg; back it up please.
