This is certainly helpful. Last night we fired up the .40 for the first time. its brand new. Ran fine. We are now waiting on the 1/16 ply as the supplier is backlogged, sadly. i ordered fiberglass cloth too, 3/4 oz. One thing i am wondering: what if I would cut out some of the interior bracing, bulkheads/stringers to make the ship lighter? I have seen some people do this cutting out ovals or circles. Any thoughts?
