Not sure qute what you mean about uploading. The default Corsair should work fine in FS9 with no modification. If you have either CFS2 or FS2002 simply paste a copy of the F4U1A_CORSAIR folder into FS9\Aircraft.
Willfly nobody will send you the Corsair as that is illegal, however there is a far superior alternative just for FS9 at http://www.simviation.com/fs2004vintage18.htm Oh and I've removed your avatar as it was a linked image and they're banned here (as stated in the sign up page)
There are two types of aeroplane, Spitfires and everything else that wishes it was a Spitfire!
also possibly there are effects ang gauges and all of those bells and whisles in the main FS2002 folder that need to be collected and copied to FS2004.
