Have not done any aircraft in 3dmax, but I have in Gmax. I never finished my projects as I never figured out hierarchy. I have used 3dmax for buildings though and the functions between the two are very similar.
This is my C-123k project that I was making to release as pay ware that would be used as a fundraiser for our real C-123. This is in Fsx,


This is the fuselage for C-123 v2 as I was not certain about the first...

Another was this Cessna 404
