Hey Art,
I will see if I can get a copy for you from Kreth. The wing is built different then what the plans show. The ribs are the same, just the spar is different.
It is a real tough wing built the way the picture shows. Kreth made a real slick jig for it. Just slip in the ribs and the spar in along with the LE and TE then tack it. Pull the wing out of the jig in 5 mins.
I think you could almost drive a 16 Penny nail with it.
