Thanks. I made a Free Body Diagram if you will of a plane with dihedral, and one without. The angular momentum balance made so much sense I thought I'd figured it out. What I failed to see (most due from my never have flown a model airplane before!) is that as the plane changes positions, air is not coming at both wings equally, and that the AOA (angle of attack) is constantly changing with respect to the position of the plane.

It still is a rather simple, yet effective tool for trainer aircraft. It's funny how things can make so much sense after shown to you, and you think 'why didn't I think of that before', like the wheel!
