Kind of what I was thinking CP. I was able to scrounge up some 1/8 X 1/16 spars and cut the ribs with less than 1/16 between the spars. (Yes I cut extra as I knew I would break a few) So with 1/32 caps it puts the wing at right under 1/4". Nice and slippery. The prop is another issue. A 5X3 cox is too chunky to whittle down. I'm thinging starting with an APC with a 3" pitch and dealing with the moster hole issues in the middle.
