It's a couple of pages back, less of a design and more of a load of stacked together parts. This probably won't be a competition machine just for whiteboards and demos for now as i don't think it would be competitive i just like the design. In terms of having the energy i'm going to try and get the disc around the 4kg mark and get the speed around 5000rpm, the disc in the picture is only 6mm thick whereas the finished one will be 12mm.
