Now that the spar box is installed in the correct position, it's time to set the wings angle of incidence (AOI - the angle at which the wing will travel through the air).
Using a digital app on the iPad verified that the wings were both set to the same angle of incidence. Time to drill the AOI holes through the wing root into the forward and rear hard points of each wing end.
The kit now includes the AOI pin and the instalation process is easier than the manual. Just be sure to mark where the hard parts of each wing are so that you can drill through the inside of the fuselage through the center of the hard part.
DON'T DRILL YET. You must measure the AOI with a digital level accurate to within 0.1 degree. All of this is covered in section 11a. That's when you drill.
