Hi Larry,
First of all, you'd better clarify what kind of aircraft you intend to model. I presume instead of a "DR VII" you mean a Fokker D.VII, which was a biplane fighter introduced about May 1918. The Dr.I was a triplane (Dr=Dreidecker, three wings; D generally stood for Doppeldecker, a biplane). Udet flew both; I know of at least three different Triplanes he flew (one in Jasta 11, two in Jasta 4) and several different D.VIIs (all as CO of Jasta 4).
I would imagine that you would prefer to do the D.VII everyone thinks of as "Udet's D.VII", which is usually depicted with a red fuselage and tailplane, red (?) and white diagonal stripes on the top wing, with "LO !" on the fuselage in white. There is only one photo of this aircraft that I'm aware of, and it shows Udet standing in front of the tailplane. Unfortunately, he blocks most of the aircraft from view. However, you can see that the tailplane had a white chevron on it, and the words "Du doch nicht !!" on the elevators.The latter message has been the subject of considerable discussion on this site; the short translation is something like "Certainly not you !!", and it was intended as a taunt to any Allied pilot who might get on Udet's tail. The ironic thing is, Udet did not fly this a/c for long, and was shot down in it on 29 June 1918, by an alert gunner in a French Breguet 14. Udet barely escaped with his life in a hazardous parachute jump.
In my opinion, this aircraft still presents questions concerning its actual appearance. Some have suggested that the stripes on the top wing were actually black and white, not red. There is a very good discussion and profile rendering of this plane by Dave Roberts in "Fokker D.VII Anthology 2", from Albatros Productions (however, Dave leaves the final conclusion about colors to the reader).I imagine you can locate some of the more typical color views of this aircraft by doing a search on the web; you might try Gaston Graf's excellent
Jasta Boelcke website at
www.jastaboelcke.com/de, I think. Try the links on this website. You might also contact Dan-San Abbott for more info.
I don't like to blow my own horn, but if you're interested in Udet's other D.VII's, you might try my booklet on "von Richthofen's Flying Circus", also from Albatros Productions,1995.
I hope that was of some interest.
