Decided to cut in the landing light fairing into my wing tips. Traced the lens shape onto the wing tip and cut it out. Made a 1/2" shoulder along the fairing itself and cut that out of its mold form. Read the instructions over a couple times where it said to cut the tube in the wing tip to make room for the fairing and looking at that tube inside the wing tip gave me some trepidation about making sure I understood the cutting of the tube. So I did what many Kitfox builders do - called Brandon at the factory. He confirmed cutting the tube so off I went. Started slow removing only a minimum section of the tube and then fitting the fairing. In the end, the fairing fit in nicely but the landing light itself has a heat sink on it that protrudes back behind the rear of the fairing itself. So I wound up measuring 3/4" behind the back of the fairing and removing more of the tube. My ruler said that with the landing light installed, I should have about 1/4" between the back of the light and the cutout tube. Putting it all back in after the cut, my eyeballs said my ruler was correct. So now I am ready to epoxy the fairing which I will do after I finish doing the same install to the left wing tip.
