Well, snitch, the wing span is right now 96" and cord length is a constant 14-3/8" for an aspect ratio of 6.7. Not so easy to determine the lift coefficient. That will depend on load factor and angle of attack in flight. Don't know how to tie down an estimate for those. My target is for a dry weight of about 15#, but a fuel load of up to 2.5# (50 oz tank - another mission for this bird is cross country flight with up to 1 hour's range).
