From what I understand there is a potential issue with the lower wings -- they tend to want to point down too much -- see comments in PrzemoL's build (toward the end) for more info.
They indeed seemingly do so. Yet, one can view it differently. As far as I remember, in the instruction book for WNW Pfalz D.IIIa there is a photo showing the trailing edge of the lower wing which is clearly bent up. I suppose it maybe so with Albatros, too. And this is precisely what one gets, after pushing the tips of the lower wings up to close the wing cellule. Anyway, with rigging added it is all stiff and holds together just fine.
All this notwithstanding, I can report another small problem I had with the lower wings. Their fit to the slot in the fuselage/cockpit-underside is very tight. And pressing the wings home may rise one's blood pressure, if one thinks of a possibility to damage the delicate interior elements. I had to taper the edges of the wings location pins to slide them into the slots and then gently press praying not to destroy anything.
BTW, fine progress on your build, Softscience!
