Hey thanks for the kind comments guys!

I will happily step up to normal if people think that is the right thing to do- it's like being promoted!

DrKnow: Yes it's GI_Joe, I was just messing with the settings, changed the lighting to yellowy, reduced it on the slider bar to about 75% (tip from Caligraphics there, grateful) and the intensity down a tad. You can pretty much render any colour you want and I prefer it not as stark as the standard one gives you. It's all polys with the exception of the centre of the wheel and some of the bolts which are subds to get things smooth without too much weight.

Laurie. No secrets! They don't move btw so I can't show you them doing that!. There is an animation script on HighEnd 3d for Maya that creates tracks on an animation path, IIRC but I wanted to make more detailed static ones. So for mine I cut the basic shape out of a cube (with 2 'teeth' on one side and 3 on the other), extruded some faces to make them stick up and look more rounded using soften normals to get a nice edge and duplicated them. For the ones at the ends I joined them together and rotated them round to fit the sprockets. I can post a pic if it would help.

Eagle thanks- the bolts are just poly cylinders with the top face extruded to make the rounded bit, then converted to subds and duplicated and moved into place.

Howard and Adl- thanks!

Quick update, most of the main shapes are in place now including the power wheel (TM LOL) with supports, lookout's tower (with hydraulics) and rear passenger cage. On with the details (and if I have time some mice, which I am much happier making!).
