Yes this is one of my models (along with TB2 & 3) that I have also posted on 3D Warehouse - rendered in 3DS Max with a simple environment map for reflection, a sky light and a direct light to give shadows.
It looks awesome, I wondered how it was textured but if you did that in 3DS Max it explains a lot Could I do some renders with your Thunderbirds models in the future, if the right credit is given of course?
Certainly - have fun rendering. It would be cool to see them with nice particle effects (engine jets/rockets, etc.) or in more realistic environments. I've tried matching them into photo backgrounds but I don't have many good images to use for this yet. Animated fly-pasts would look good too - if you had the right sound effects.
