I'm still amazed at this combination. It's similar to kite building but instead you get to build a killer robot. With the carbon fiber rods and Kevlar string and the incredible ca glue. This is a fun way to build an awesome robot. don't forget to throw in a carbon fiber sample pack. you can glue the rods to the thin sheets and drill holes in the sheet to sew the thread through it can make some very solid and strong frames.
