Perry frigate - Insane Detail question No. 4

Done that job in 1/35, but 700????
I simply found a piece of (I think) missile body in the spares box and then added the 'fin'. I used a piece of thin plastic card and cut a circle from it. I then cut a tiny circle from the centre of the disc and then cut a thin 'slice' - like a triangle from a circular pizza - removed the slice and then carefully stuck the two cut edges from the remaining disc together. I started with a very thin slice and then put the edges together to see how well the cone shape would look. It took a couple of attempts to get the correct shape for the cone. Once satisfied with the shape, I then drilled all the holes in the cone before gluing the cone into shape. However, in 1/700, you probably won't bother with the holes.... I trust this technique may give you some ideas. You would need a very thin piece of plastic card for that job...
Hope this helps.

Well, after several attempts with ever smaller bits of stretched sprue and ever smaller bits of plastic, I gave it up because every attempt looked more like a Harpoon missle than a MAD bird, at least to me. My Seahawk is just going to have to be naked, I guess.
