Go back through the manual and double check the wing mounting instructions. You either have the wing not centered, or twisted on the fuselage. Mark the center on the wing and the fuselage and see if this helps. You shouldn't be able to twist the wing but that doesn't mean that it is impossible.

I had to go to Tower sight to see how 122 grams added up, the rest of us in KY use ounces. 4.3 ounces is too much, What engine/prop are you using? Is the wing seated on the fuselage as far forward as it can go?

You should measure the distance to the wingtips from a centerpoint on the tail of the aircraft. Your Hor. stabilizer could also be crooked.
