version 6
As I could find no evidence of what the prop should look like on the actual ship, I just took a stab in the dark and picked one that looked about the right size. I believe the technical term for that is W.A.G.
When you say there are black pixels around the radomes, you aren't referring to the border are you? I thought it was supposed to be black. I did a background check around the radomes and it went solid right up to it. As for the differing shades on each radome, the forward one I have a lighter shade because it just represents the seams, while on the aft one, the real one has those very pronounced panels you can actually see, so I made the color of the grey a bit darker to represent that. look at the pic
lazer_one took of her in port, you can see the difference between the forward and aft radomes, and thats what I was trying to represent.
