Forget about weight, you better have have a LOT of resources available to design and build it. After seeing the 118 machine up close, this isn't something you think up overnight. The weight also is greatly affected by the types of wheels, motors, chain etc that you choose to use. Try to look at the pictures from 111,118, 71 and others to pick up the tricks from each for weight savings and efficient design. Just be ready for the complexity and hope that the playing field is flat if you choose to develop it in the off season!
