Mike P.- no, I'm not looking for a database of spars. I was just inquiring aboutspar thickness. My analysis includes solid and routed, 1" and 3/4", spruceand fir. Besides the built-up I-beam and the UK box designs, I will also NOTbe studying anything deeper than the standard 4-3/4" deep FC-10 spars. Peoplewho use the Riblett or other airfoils may be able to use a deeper spar, whichwill provide increased capacity, but I'm not going there.--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:

Jim B.: is this a test? ;o)I am not studying the J-3 or Champ but after I get done with the Air Camper, Imay be interested enough to take a look at those others.--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:

Jesus, Guys, enough!!If you spent half the time building that you spend worrying over minutia and runningstress analysis on an 80 year old design, we would darken the skies withPietenpols. Pick a max gross comparable to others and go fly the damned thing!!GeneOn Jul 31, 2014, at 11:12 AM, "taildrags" wrote:> > Mike P.- no, I'm not looking for a database of spars.
