Default Polydihedral question?

I just finished building a Dynaflite butterfly and the wingtips are about 1/4" difference in height up from my work surface when each panel is laid side by side, trailing edge to-to trailing edge. The total wingspan is 99." Is this insignificant? Does anyone know if this will be noticeable with the flight characteristics? I have not checked the distance with the wing seated on the aircraft yet. The dihedral could possibly offset this but I was just curious at this point. I might be able to knock some of this down when I cover it. Any input or opinions are appreciated -thanks!

You won't notice it at all.

WHat soarrich said. The only one that knows is you. And those that see this thread. It will not be of any problems.

If anybody suggests that one of your wing panels "is a little off", ask them which one?
Be more concerned about sufficent, and similar washout for your test flight. Enjoy your Butterfly, thousands have -good choice-

Do a lateral balance on the plane. One wing that is heavier than the other will likely have more impact than the slight difference in dihedral. Add weight to the wing tip of the light wing.
