Loose the caps! The correct spelling is monocoque. The dimensions may be slightly too small to get four large motors in there. You have stated what powers the shell, but what powers the bar? Does the shell have any teeth? You only stated ones for the bar. How much kJ can the bar give out? Does it run in the same or opposite direction as the shell? State the turning circle even though it is self-explanatory. What is the bar made of? What shape is the bar:

----- or /----- ? (If that makes any sense)

I am also concerned about the weight. Try getting a 4mm Hardox shell (you say 16kgs), 2x LEM130 (6kgs), batteries for the drive (~10kgs), four wheels (4kgs), a spinning bar (you say 20kgs), 2x Hardox teeth (you say 2kgs), foam, weapon batteries (~15kgs?) and 2x B42-500 (~20kgs) into the weight limit. This is bearing in mind I probably underestimated the batteries, and I€™m pretty sure you underestimated the weight of the shell.

But I€™m hopeless at weighing vapourbots, and as you can see my rough tally works out as in the weight limit. So wait for someone else to come along to ensure that it is not overweight.
