Rick,
I don't have an authorative answer for you but I do have a question. I'm working on an RC Albatros DII. I haven't decided on the whether to use a 2 or 3 color scheme for the upper surfaces but its the lower surfaces that I'm stuck on. Should I be using a light blue or a doped fabric finish. The fuse is stained and varnished wood. From what I've been able to gather from pics of models here and other places on the web and in some printed sources, I'll be doing the front of the upper fuse and around the nose a grey color. If you have any insight on the struts' (landing gear, cabane and inter-plane) color I'd appreciate the help.
BTW, I usually use a soft edge but not a blurred edge to my schemes on the upper surfaces. I don't think they used spray guns to apply paint during this period, so they'd end up with fairly hard edges. I may be wrong but logic points this way.
Thanks,
Dave
