RE: 1/5 Sig Cub Build Pictures
That would be a great scheme. I always like having something different. There are several military schemes on the net but I have not seen one at my field. That is why I chose the scheme I did. Only issue I have would be cutting the top stringers. I would go with the look of the drawing more than the photo on Airliners.net. You could make a panel line to make the rear look removable without loosing the strengh of the tail.
Masking: I would use fineline tape. Flat masking materials are hard to lay down on the fuse and wings and maintain a good seal.
I forgot to mention. Prior to spraying each color for the roundels I went around the tape line with the base color. Example, when I sprayed the blue I had gone around the tapeline with olive drab to seal the tape for leaks. When I painted the white over the blue I went around the tape line with blue prior to spraying. I really soaked the tapeline with paint using a q-tip to apply the paint. The intent is to allow any gaps on the tape to be filled with the base paint color. This paint was immediately wiped off the airframe with care not to pull the tape line up. Then the overlying paint was sprayed. This techinique will result in razor sharp tape lines.
