Trev,
That wing is real nice, I appreciate the attention to all the detail of the rigging. I will second the vote for doing the reinforcement webbing in the wing!
I've bascially used the same scale airfoil that Art has on his big 1/3 E.I (a proven flyer)
To adapt it more to the E.III one I made the LE slightly thinner
Are you implying that then that there is a difference between E.I and E.III airfoil used? I don't doubt that there is a difference, as Fokker and other designers were surely experimenting with the shapes on a continuous basis in those times. I found only one reference about [link=http://people.bath.ac.uk/en3hea/page2.htm]early airfoil designs[/link] but I have not been able to find anything on the German aircraft.
