While the kit calls for some dihedral I am going to make it like a full size Cub and remove all but a tiny bit of the dihedral. The dihedral would begin where the wing meets the fuselage, like the real Cub. My 1/5 scale flys great with no dihedral and I believe that kit called for a small amount too.

Here are some full size photos showing the dihedral.
