RE: Scratch-built Fokker Dr.I 1/6 scale
I don't know what Leaman's sources were. He is the author of this book, which would probably tell: http://www.amazon.com/Fokker-Dr-I-Tr...1345287&sr=1-1
My source is an earlier article of Leaman's that I got from MAP, a Scale Models Warplane Special, R L Rimell, ed.; can't find any date on it...probably 15-20 years old.
The stab in the Nieto drawings has the leading edges at 45 degrees to the center line, forming a 90 degree angle with each other. The Leaman drawing shows a more acute angle; it looks right to me when looking at old photos. The rudder shapes are a little different.
The upper longerons are straight on the Leaman drawing vs curved downward in Nieto, but the tail posts are the same. Of course, that means the bottom longerons must differ too, which they do, and that in turn affects the angle at which the plane sits on the ground. The difference is 21 degrees (Leaman) vs 18 degrees (Nieto). If you carry the center line back, it intersects the tail post about 2/3 down on the Nieto drawings. On the Leaman, it intersects below the rudder but above the skid.
The sub wing over the LG appears to be a little negative compared to wing incidences on Nieto, but appears the same on Leaman, which unfortunately means the trailing edge on a model is even more likely to drag on the grass.
I think the axle is very slightly more forward in the Leaman drawing. I can't really tell. My VK kit, which is supposed to be faithful to Nieto, has the axle slightly back.
Unfortunately my Nieto drawings are from the MAN book, and work out to 50th scale, whereas my Leaman drawing is 48th scale, so direct comparisons are a little difficult.
Do you want a scan of the Leaman?

Chris, if I were you, I think I'd just stick with the DF drawings.

RE: Scratch-built Fokker Dr.I 1/6 scale
No trouble at all...PM sent. I really appreciate your threads on WWI builds and especially this wonderful scale structure build. It was this thread that alerted me to the longeron discrepancy. When I started building my VK triplane I thought I might as well fix that. But once I started measuring I couldn't stop. It has slowed me down some and definitely caused me to veer from the "no frills" approach I started with, but it has been absorbing and fun to make some corrections to the kit. The level of detail and finesse you show us in your builds is way beyond me, but my objective is really to make a "scale model for everyday flying", as Gordon Whitehead says. The VK kit provides a good basis for one, I think, though the structure is a little heavy in places, and it is based entirely on the Nieto drawings.
