I will eventually be installing the Aerosport overhead panel along with the overhead vents, and to get air up to the vents I need to have a couple of NACA vents and ducts installed in the tail cone. As there are no NACA vent holes in the tail cone side skins, I needed to cut those out myself. To avoid reinventing the wheel, I did some research and decided to place them in the most common builder location starting approximately 5 rivets back from where the fuse skin overlaps the tail cone skin, centered in the area between the tail cone longeron and the uppermost J-channel. After marking out a centerline (making it parallel to the cabin mid deck since the tail cone angles slightly upwards along its length), I used a 3D printed template of the NACA vent opening to trace it on to the skin at the chosen location.
