These templates should be about actual size, if they are not, I included measurements for the sides.  Aft fin (on the left) has the small edge measureing 14.5 mm, it look skinda fuzzy in the pic.  Left: Aft Right: Middle
Simply cut out of paper and stencil onto balsa wood for fin pattern.  As always grain should be going at about hte same angle as the leading edge.   I left out the cool background for this page to make it easyer to print for the templates.
