I see no one has answered your question. Setting the angles on the spars is what creates the correct washout. Once that is done, and you keep it that way through the installation of the foam, sanding, and glass layup, it will be right in the end.
I have not ever had to do this because both of my KRs came to me as projects that already had this done, but that is how I understand it is done. Someone who knows otherwise, please advise.

Heath - Lexington, SC -----Original Message----- if you keep the horizontal line on the airfoil plans.....will the washout be correct when you go to fiberglass or is that something you have to still build in the wing?
