Hi Wing_nut;
no problem, glad to help.
- yes, the exact width is somewhere around four feet and change, I would imagine different producers shipped slightly different widths [as are the exact colors from different suppliers hotly contested] **watch the edges of the decals closely, some people have seen black borders on the outer edge - that should be trimmed off, it's leftover from the decal printing process, trapping is not quite right]
- yup -, exactly right, if it lines up with a rib or not.
- you can do chord wise [wing tip to wing root] - that was done, but rare, just check your reference - personally I wouldn't want to try and work with a decal that large unless I had to. Your copy/past mockup is far more common [make sure the decals but up like between panel 2 and 3 or you will see the seam under the rib taping... these wingnut decals are pretty impressive]
if you take a close look at the wnw instructions they do show roughly where the decal edges should meet, see below the dotted lines, on the right image - the dotted line above the radiator matches my roland below [which I incorrectly covered with rib tape!] the dotted line below also shows a joint between 2 spars, but mine actually would up on the rib.
You can see all the build pics here: http://www.onetofortyeight.com/Assets/Galleries/RolandDVIa/ - they might give an idea of how I laid them out [the Albatros will be similar]
Also - there's an LVG a directory up: http://www.onetofortyeight.com/Assets/Galleries/
Be stingy with those decals, cut templates, there is next to none to spare!
-best regards
