Has anybody built the Balsa USA Bristol? Thos e of that have know how great their instruction handout is (Not). I'm currently working on the first wing half and have one question. There is no mention of rib #1 in the instructions or on the bill of material list. I have found what looks like 4-1/2 ribs that should be the choice to use as rib#1. I would like to have somebody else give me a head nod to confirm that I'm on the right track. The 1a rib piece also doesn't look quite right (seems a little small). There is really nothing else to put there.
