Hi everybody,

The amount of dihedral that I build into a wing, for me, depends on the type of model and wing the kit has. If I was building a plane with a constant chord wing, then I would build the plane with the suggested amount of dihedral (such as a four star 40, for instance). If I am building a double tapered wing, then I will build the wing upside down, with the root ribs glued at 90°. This causes the top of the whole wing to be flat, but the dihedral is built into the wing from the bottom. This happens because each rib from the root to the tip, gets smaller in both dimensions. A good example of this is the Ultra Sport wing. I build my Ultra Sport wings this way and it comes out with just a little less than the recommended dihedral. Why do it this way? It makes it alot easier to join the wings halves together. Just my 2 cents.

Happy flying and soft landings!
