This is where placing the wings to the plan is very important. Some kit instructions state that the rigs are to be snugged up to the shear webbing and the slight differences will not matter. That next to the last rib is what I use to set the wing. The tape measure rests solidly in the juncture of the rib and trailing edge. place a straight pin in the center of the end of the fuselage and measure to it shifting the wing until both measurements are the same. Hold the wing in place with masking tape and drill the wing hold down holes using a guide block to set the angle. Notice the slant of the 1/4 20 tap.
