Advice on unwrapping in Blender

Nothing super complex here, but I need some help/guidance with the UV Texture unwrapping in Blender. I'm using version 2.71, but that's neither here nor there. I'm using the smart UV unwrapping tool and playing with the settings, but its hard to nail the "best" curvature to make flattening this part. If its a matter of hunting until successful, okay, fine. But if there's a best-recommended-for-such-and-such, I thought it worth asking.

So, as you'll see in the attached image, the bow (and the rear, but lets focus on the bow) is roughly rectangular with a bevel that narrows relatively uniformly. This model is designed in 1:1 scale, so when I scale it down that bevel will probably blow out and may have to be represented with shading. So, I should be left folding this out to four tapering petals, in my mind. But for the life of me its not slicing as clean as that at all. Perhaps I'm missing a step? Maybe I need to set seams?

Anyhow, thanks in advance all. Hopefully you've a hint that gets me going in the right direction again.

Hello sreinmann.
Now I am solving the same problem. The problem is unwrapping a narrow double curved element. Some solvings of this problem already appear now but my research is not completed yet. If I reach success in this task I will let you know.

Hello Dane,

So a couple of youtube videos reminded me of how this works. First in edit mode, select the edges that identify the seam that you believe would be best. On an aircraft, you might choose a belly seam. For my model, after I removed the bevel which as guessed was lost when scaled down anyway, I selected the four "corners" of the cone-like nose. With that edge(s) selected, choose menu option Mesh>Edges>MarkSeam.

We now proceed with the "Smart UV Project" menu option after selecting all your parts that you're ready to unwrap and [U] in your edit mode window. What worked best for me was to set the angle limit to 66 and the island margin to .06. I don't know why, it just worked best that way.

Your mileage might vary of course, and depending on your version and experience, your menu options might be different too. Now, after I got this all figured out, I have to go back to the drawing board as lots of details need to be "painted" in and not modeled/unwrapped for the kit. Does have me using the layers though, just in case there's a future friend with a 3D printer interested in a fun distraction.
