I applaud your experimental rib building but I wonder how much the
work achieves.

I weighed two of my truss ribs.
one in alaskan yellow cedar and one in queensland hoop pine.
naca23012 aerofoil in 4ft chord with all the gussets but not all the
strengtheners in place. unvarnished.
they are for the druine turbulent, the plans I sent you.

in QHP the rib weighs 134 grams. in AYC the rib weighs 143 grams.
143 grams is 5.044 avoirdupois ounces.

for all your experimental work on ribs you've never mentioned the
resulting weights?
ok what are they? I'm curious.
