GMAX is one it came with your FS2002 or FS2004 disks
They are in the extras section of the disks.
But one word of caution GMAx is not what I would call a tool for a begineer. There are some good tutorials out there one comes with the GMAX install. But unless you have had some experience with 3d drawing before it is a little deep. About like the Grand Canyon or the Abyss. ;D But this is the tool that just about all of the designers are using for a lot of games. I made a awesome 3d house using this, But gave up on the airplane I just could not figure it out.
There is a good handbook that you can find at any descent book store that comes with a tutorial CD as well that I have heard is great.
Oh by the way I hope you have pleanty of hair on your head as you might loose a little using this program.
