On http://www.simviation.com/fsdesign_aircraft1.htm there is:

- FS Design Studio - now in Version 3: A versatile & easy to learn FS Design Utility By Louis Sinclair - produces FS2004, FS2002, FS2000 & CFS2 aircraft & 3d objects;

- G-Max : 3d CAD style design utility specifically aimed towards MSFS. Initially came with Flight Simulator 2002 Professional Edition & is used for FS2004, FS2002 & CFS3 aircraft;

- AD-2000. Aircraft Designer 2002 v1.2 LT. AD2K2 is a tool dedicated to the designers of aircraft for Flight Simulator 2002™, Combat Flight Simulator 2™ and later version of Flight Simulator. Attention: this completely functional freeware version (password FREE-WARE) is only for private use and gives no possibility of access to a technical support. The only available help is in the tutorial file and ONLY in the tutorial file (included).. Copyright Hervé Devred/A.C.T. publishing/Michel Melchior. Download 4.4MB;

- Aircraft Factory : 'Aircraft Factory 99' was/is a 3d design program available from Abacus Publications & produced FS98 & CFS1 aircraft. Though 'Out of Print', it may be available 2nd hand - if you really want it.

None of these say anything about Flight Simulator X, which program allows you to create aircraft for Flight Simulator X?

That is correct , but if you don't want to get into trouble (It seems to me that FSDS3 its more complex for FSX than gmax ), Yes Gmax its free, and for my short, humble personal experience ,use gmax wich is also in the dvd1 You install you FSX-SDK and there it is (install it Before you apply the FSX-SDK-SP1 or 2 otherwise for reason I don't know it wipes out by applying these two Sps )
