Hehe Aaron has a point here though Paul... 2x LEM200s, 8 wheels, a vacuum system, a crusher, Hardox skirting and 7mm Ti and 8mm Steel (which I presume are in different areas rather than both all over). Its going a little overboard to say the least. If youre going for LEM200s you would have to sacrifice elsewhere as that would be 22kgs in just drive motors. Get rid of the steel and make it 7mm Ti all over. Change the LEM200s to LEM130s to save a load of weight. Cut down on the wheels, 8 are not needed. Dimensions need to be larger. Expand on the crusher description. Up the ground clearence by at least another 3mm. Otherwise, thats fine!
