Top railgun
Group 10 is the smallest one in the Sulaco paper model with no doubt, but the hardest to build too. There are lots of small parts, rounded corners, lot´s of correction on the edges and scouring the overlaps in this group. That´s why I´ve decided to give it full row of 5 stars. (Level of difficulty 5/5) Group 10 - the Top rail gun has 32 parts on one sheet.
