You CAN use milkshape to make less complicated models, but it's renders suck ass. Same with lightray except lightray's renders are slightly better if you ask me. 3dsmax is probably going to be the one you want if you really want to model like G does. I myself did a few models of my own, but never got around to doing anything with them. Think I have a p51 and a spitfire somewhere that I made in lightray. since I never got any good renders from them and I really am not that good with mapping skins onto new models I just sat them aside and said fook all.
On a side note, hows yall doin nowadays? I havnt been on here in a while.
