Using Aveo Engineering wing ZipTips that have recognition lights on the rear of the tips, I don't need to install a rear position light on the rudder. I cut out the light mount and glassed in the opening. I had considered, and attempted, to put some backing inside the cut fairing as I had seen others post online, but then determined it would make for a nicer form to put backing on the outside and lay glass inside, which I did.
The next step will be to fill in the holes and make it flush with flox, followed by finishing it out with some micro.
