I checked, and I couldn't find any available decals. What scale were you planning on using?
I miss the old Microscale Decals... they had a TON of subjects. I'm not sure if they had a "N" model or not. I know they had a set for the UH-1D/H and for the Cobra in 1:72 scale, as well as a sheet for the Loach in 1:32.
