 negative angle of incidence?
i'm building an arf biplane and need to set the angle of the upper wing to 1 1/2 degrees negative incidence, but the wings don't fit the struts at a angle of 1 1/2 degrees, it's built for an angle close to 0. i'm not sure what the negative angle is for so i don't know how to proceed. put the wing where it fits, or set it at 1 1/2?
