Here is a picture of the tail surfaces, fin/rudder
and stab/elevator. These are foam core construction with 1/16 balsa adhered
to the foam using a very thin laminating epoxy. The entire assembly is
then placed in a vacuum bag for 10 to 12 hours while the epoxy cures.
This ensures an excellent bond between the foam and balsa. You can see
some lines on the stab. This is where I intend to scrollsaw out some lightening
cavities. |

Here is a picture of the stabs after they are cut
away from the elevator. The lightening cavities have also been cut away.
This saved several ounces in the tail surfaces. |

Here is a picture of the completed tail surfaces.
Strong, yet very light, and despite what you might think, builds quite
fast. There are also some lightening cavities in the stab and fin. |
