Next I mounted the stab, or really attached it as it is already aligned and mounted. The stab is held in by 2, 2.5mm cap screws which thread in from the bottom of the left stab into the carbon fiber rods. The rods have a bit of wood in their ends to accept the threads. I drilled and threaded the holes, then hardened the threads with ca, and ran the tap through one more time. The plane comes with a roll of self stick foam to use as a vibration barrier between the fuse and wing and stab. I cut it into strips and applied it to each stab. The foam was too firm and could not be compressed enough to get the screws started however. So I went back to my standard method of using a thin bead of silicone rubber which molds to the fusalage shape.
First step is to apply a piece of polyethylene plastic (from a bag) to the fuse so the silicone does not stick to it. A thin bead of silicone is applied to the edge of the stab and it is pushed in place. After 10 minutes or so, just enough time for the silicone to start to set, the edges are tooled with a rounded piece of wood. A toothpick or a small popsicle stick shape works. The edge is sharpened but kept rounded and run along the edge of the stab keeping the "point" as close to the stab as possible. Excess silicone is forced up and away from the stab and stays on the polyethylene sheet. After a few hours the stab can be removed and the plastic sheet peeled away to allow the silicone to fully cure. This worked well and the final fit of the stab is tight with no play.
