I have been browsing the FSDreamteam forum for the acceleration Hornet and some talented people have done some really cool modifications for the F-18 hornet. One particular addon, the Sludge Hornet was supposed to be released today over at Flightsim but it has not showed up yet. Also there is a custom soundpack for both the Hornet and the T-45 by Dino available if you browse the forum. The soundpacks and mods really breathes new life into the Default Hornet.
Also big credit to the guys who have done this, it is very nice to see that kind of dedication for one of the default airplanes in FSX.
