Okay, I finished the plane I have been building these past three days.
Far from perfect.
I don't know if the plane is a Spitfire Mk V or Mk IX. I have seen this same model with both names.

here with link to template. I had many problems building it because of my inexperience and because the instructions are not so complete as they should. And I haven't found pics of the model built by other people, only the 2 low resolution pictures that appears in the download link.
