I am in the process of building a Pilot Christen Eagle scaled up to 68-inch wing span. The CE uses a fully symmetrical wing. The wing cord will end up at 11 inches and should only be about 1.5 inches thick.

What if I make the wing thickness bigger, perhaps 1.7/8 inches thick, did I improve anything in terms of slow flight speed or did I just add useless drag?
