I have no idea how to go about this and my other scratch built jet pack has a flat back, but for those of you who built your own. I have 1 question, how in the world did you do the back? Its thicker at the bottom than at the top, and the back is curved. Not to mention the upper part is about an inch wide, Do you just glue the material to it like an L shape and sand it down?
Maybe this picture will help explain
I need some info on how to get the side view effect.
