Because the aileron has a constant cord for its full length and the wing has a double taper plus sweep back there is a very slight angle change in the top and bottom of airfoil at the wing tip where the aileron connects to the tailing edge of the wing. I’ve checked and re-checked the plans and wing template and everything is the size shown on the plan and the kit wing tip tracing. The trailing edge of the wing tip template would need to be about 1/32” thicker on the top and bottom to make the airfoil not have an angle change. I can’t tell from the Blue Angel kit pictures for sure but from the change of angle of the red wing stripes it looks like it might have the angle change at the tip. It is equal on both sides of the airfoil and wings so it is not a problem.
