I picked up a Lego SSD a while ago and my son and I just finished building it. To me, the included Star Destroyer looks a little undersized. I thought the ratio was 5:1 (SSD 5 km long and ISD 1 km long). It looks like I was mistaken and an SSD is actually 11 km long. So that would make the Midi Star Destroyer too large. I'm looking for something in the 6" range. The included Star Destroyer is about 4" long. Does anyone have a good plan for building a 6" Star Destroyer or can point me in the right direction?
