All of the programs for balsa stiffness that I am aware of depend on a deflection measurement. The deflection is measured by standing the balsa sample on a scale and pressing down until you get the maximum reading on the scale with the balsa bending. This is the number that goes into the formula. You can download the program from Tim's website.

  There is a method to calculate balsa stiffness, by John Taylor (INAV
  108, p11) for which you have to cut several strips from a balsa sheet.
  Also Bernard Hunt did a study for balsa sheets. Both require (among
  other tings), the deflection of the sample. Lately, I was advised that
  in Tim Goldstein's Indoor Duration site there is a program that saves
  you the calculations, but it does not ask for defection. Anybody there
  could help me to understand how could this be calculated without that
  figure?
