Thanks Mark, I appreciate the help. I think I can duke out the bill of materials, however, I still have a question on building the wings... that part should not matter between the 40 and 60 size CD. The part I am not sure of is whether or not the wing panels are built flat on the plans rightside up with no jigging required. In other words built with the bottom spar on the plans with the flat portion of wing ribs between the spar and TE contacting the building board.

Any help would be greatly appreciated.
