William, I just took some measurements off the MAN plan. If you look at the area where the dive brake is on the wing plan view, you will see a dotted line that is the TE of the foam core. I you extend that dotted line to the center line of the wing and measure from that intersection to the back edge of the LE it comes to around 11 3/8" My guess is that this is close to correct and that the fuselage elevation view is too large. Hope that helps. Still, I find that these magazine plans tend to have errors. I'd be curious to know how many Curares Prettner built and how each one differed. No telling what the various kits were based on. There's another kit being sold in Germany, too.
