Exactly which blue foam product are you using?  I've been using the Dow High Load 60 in some of my composites work for a few years and it's strong stuff.

I work on it every day in between "Build Nights".  We began construction with the long work benches in January and have built all 6 tail spars.  We are currently framing up the fin and rudder.  We did some engineering tests and determined using 1/2" blue foam ribs capped with 3/23" spruce cap strips would make ribs that are lighter and stronger than those made out of spruce sticks and ply--and speed up construction immensely.  I hope you decide to build one.  The build is a bit tedious, much like a large model aircraft, but fun overall.
