I'm not sure how nominal airfoil sections affect flying for these
small planes. In any case the section will be accurate at the ribs
only, the covering sags between them. Even then you'd need to use
laser cutting to get anywhere near the proper section.
I suspect that there are three things only that you should worry
about: thickness, camber and the chord-wise point of the max camber.
Thus it might be worth trying a thinner, less cambered foil.
