<< Thanks Joe....It's time for the dumb question. Why are there more layers
on the top rather than the bottom of the canard and wing. It seems most
airplanes are built with the lower spar cap being the beefyest. Can

Carbon fiber is strongest in tension , the upper spar is in compression and
needs more fiber as the compression allowable strength is less than tension
allowables.
