The "progression" that I recommend is:
1. gmax default tutorials - to learn the basics of using the program (especially if one does not have 3D modelling background)
2. Aircraft Modelling Tutorials - such as the 3DWorld Magazine Gmax Tutorial at
http://www.aerodynamika.com/gmaxtut/gmax000.htm, and especially the "Stupid Idiot's Guide to Making a Plane with Gmax" (
http://www.simviation.com/gryphon/tutorials/gMax_00.htm)
3. "Specific" tutorials, such as any of Firestriker's tutorials (to which I've linked from the FFDS Tutorials Section) to deal with specifics - scaling and setting up views, boolean operations, making a wingtip, etc. etc.
For these and more, check:

http://bhoth.pair.com/freeflt/tips.htmAlso VERY important is reading the design forums here in Simviation and the Freeflight Design Shop (
http://www.aerodynamika.com/forum.html)
Once you get the "hang" of the program, the pointers and tips the come up in the forums are invaluable.
