Streamlining the Horizontal Stabilizer Tips

Shaping the stabilizer tips is straight forward. I opted to use the foam that was included in the kit. After sanding it (taking care not to scratch the weldment), I applied a thin layer of Hysol. The end result is surprisingly strong! Let’s see if it can withstand the heat when attaching the fabric.

Horizontal stabilizer and elevator with ribs installed

Finished the elevator by adding rib stiffeners to all free-standing ribs. The local hardware store indeed sold a nice 2.5mm ply labeled ‘For aircraft use’! Two layers of PolyFiber Epoxy varnish added for the trips to the Caribbean.

Adding some rib stiffeners

Adding rib stiffeners to the horizontal stabilizer.

Since the ribs don’t have cap strips, the long ribs show quite a bit of flex. Adding rib-stiffeners to those ribs will prevent them from bowing. The stiffeners are glued to the side of the ribs with a bit of Hysol. (Note the re-purposed laundry clips to hold them in place for ~24 hours. I guess I have to use the dryer from now on…)
