Just measured mine for you - the fuselage is 10mm square section (11/32" in confusing US units), and, as built, mine has 17cm (6.5") OVERALL dihedral measured to the tip of the trailing edge (i.e. if the wing was mounted in position, the two trailing edge tips would each be 8.5cm (3.25") above the horizontal).

Hope this helps,
Cheers, Phil
