Naturally, I'm making a Boeing 247.  ;) Oh, does the scale have to be in millimeters, or can you put it in inches? (Normally I like the metric system, but bigger units are easier  ;))

It is better to use the metric system. So millimeters is best. :)

Make sure you are starting gmax using the FSX_Gmax shortcut. It can be found in <Gmax>\gamepacks\FSX_GmaxGamePack folder. It loads all the necessary scripts used to create FSX models.
Another thing you need to do is: ALT > FSTools > LODNameTool > Click Create new GUID for this f.... > Friendly Name: (just use the name of the aircraft, boeing247, in this case). If you don't do that, you can't export to the FSX mdl (it won't work in FSX).
