Not decided on top armour yet. If there's weight I might go for hardox, otherwise it'll be aluminium or polycarb. Thickness will probably be 4mm if hardox, 5mm if ali or 6mm if polycarb.
Chassis height is 85mm, wheels are 120mm and the skids at the front are 130mm.

Cad program is Solid Edge, used by our uni as they could sell it to students for £5 a licence. They've now installed Solidworks on all the uni PCs which is more the industry standard. I really need to learn Solidworks, it's not too different from Solid Edge but because I know how to use Solid Edge I keep on opening that up rather than trying to learn SW.

And I only buy a Sub or two a month when I can't be bothered to cook :P

Mart, yeah I'll send you a copy of the old cad. What cad program do you use, or is there any particular file format that would work best for you? Maybe tomorrow before I send it as there are a couple of bits on it that could do with being updated
