Thanks!
I will post some more photos later, it may take some more weeks to find the time to get the remaining finishing work done.
Underside is white with wing and stab showing red stripes running from leading to trailing edge, gives a clear contrast to top side.

By the way, there is a set of Aurora stickers, but only one in a smaller letter size (for the fuselage...) and one in lager letters (for the wing, I´d say).
Anyhow, I would like to see both fuselage sides wearing the Aurora name. I may have to ask a print shop if they could duplicate it for me.
