That's a good idea. IIRC the kit has a deep trench molded along most of the 
rib, so careful sanding might be enough.

Modern airfoils fly better! Miniature wings just don't behave as the 1:1 
airfoils do, as there are many aerodynamical factors involved. There's also 
the factor that tissue paper don't have the same properties (elasticity, 
shrinkage rates) that real doped fabric had. Mind, modern reproductions 
using modern fabrics make that repros don't fly the same way they used to 
with natural linens.
