Empennage

Empennage Fairings (2 hrs )

Cut fiberglass patch that cured overnight, and trimmed to fit into Vert Stab Tip Fairing.  I prefer to inset about 2mm vs flush, so I have better clearance to swinging Rudder, but from sides appears only 3mm clearance.  Kind of matches appearance of Vert Stab meeting Rudder, Or Horiz Stab meeting Elevators at hinge lines, too.  Plus I was able to force Tip into more accurate profile matching Rudder Fairing.    I inserted patch, then "tacked" into place using cyanoacrylate glue.   This allows me to immediately follow up with reinforcing with fiberglass strips and resin on inside.
After fiberglass strips on inside cure, I'll add "chamfer" of epoxy filler on outside
Since I had extra epoxy resin, I added 410 Microlight to peanut butter consistency so I could apply another layer to LH Elevator at transition from Tip to Alum.  This was after sanding first application...and this will likely be final.
Second application of epoxy filler...after sanding first layer.
