Although 3DSMAX does look great, so does GMAXand FSDSv2. Go to any FS2002 Screenshot forum and just have a look.
I wish SF:P1 supported GMAX and FSDSv2 aircraft, I have a group of friends who would love to design some aircraft for this game....and they are VERY good modelers (I can't model a box! LOL). But they can't afford MAX....like most people I'd imagine.
It's a shame that a sim as great as this and as open ended as this is limited by the simple fact that the model design tool is just flat out to expensive for most of us. :(
