I worked on the fit and finish of the left and right landing lights to the point where I am satisfied that they will not contact the wingtip fiberglass during operation (as specified in the instructions). I am also seeing 3 degrees of difference between being perpendicular and the light at the midway point of adjustment. That's about as good as I can do because the adjustment screw doesn't even go out 3/4" like the instructions say - so I am calling it complete. Next I would be gluing the third mount into the wingtip, but since the wires are short I will wait and glue the mounts after I have the wiring installed in the harnesses.
I also started figuring the position light install geometry... again, reading the instructions, it says to draw a line from the wingtip apex to the midway point aft – which would have the position light angled down. I feel like it should be mounted straight and not angled – and my buddy Rob was in agreement as that’s how he mounted his.
