If foam testing turns you on, check this link; http://groups.yahoo.com/group/Allegro-Lite/files/Skin_Stress/ This is in the files section of the Allegro-Lite group. Check, in particular, the the foam modulus and foam stiffness files. This will tell you the Young's modulus and how to measure it for common foams. This far more useful than the unreliable and less meaningful manufacturer's specs. Phil RCSE-List facilities provided by Model Airplane News.
