I used gmax back in the day when I was playing CFS3 to model old airplanes, it's really similar. This program is easy to pick up but difficult to master. There's just so much advanced stuff you can do. I actually got pretty close to having a good model of an F5U "Flying Pancake."
yea, isn't kage like the master of this? or am I thinking of some one else... oh, the roller coaster looks nice, but Its hard to tell what it is at the moment.
