VERY nice! Good choice of subject too... not something you see very often.
I've been seriously considering doing a "semi-scale" version of this... in a slightly larger scale. (say, about 90% scale)
It is the only strut-braced parasol I can find any decent info on from the Central Powers side of WWI.
I'm curious about your choice of colors though... I understood the camo scheme on this aircraft to be grey tones, but I might be wrong. What lead you to that choice of colors? (And my curiosity is based on my desire to build one, I'm not sniping at you here! I want to be as accurate as I reasonably can.)
Also, where did you get decent 3-views? From what I've seen of the actual aircraft (one side view photo from the period) your profile looks VERY close if not spot-on, and the wings and tail surfaces look right... you obviously had a good source of information!
