I am trying to remember exactly where I saw this but I did download the picture. One too many Fosters, I suspect or simply a "senior moment", however, one KR builder built a vacuum horn into the wing fairing. This made for a very clean and neat installation. I was going to do the same thing until I found a very reasonably priced (and NIB) electric turn and bank indicator for my KR making a vacuum source unnecessary. Anyway, unless you plan on flying through weather and doing your best to ice up the bird anyway, icing is not a problem. Nesting bees and bird might be, but icing should not be a concern. Now where did I put my Geritol?
