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.
