yes, all the files in there are freeware except the A-10 which comes from Alpha Sim for $8.
it's the only decent frame rate A-10 that works in FS9. Kirk Olssen's is to detailed and many have issues with no landing gear.
Here is a list of the main AC files needed. I know most of them are found here but the author who did the skin work used AVSIM more than here for some reason??
