Horizontal and Vertical Stabilizer
1. From the 1/16” soft balsa sheet remove the vertical stabilizer components and glue
together as illustrated (first photo). The top of the horizontal stabilizer has two etch lines
scribed down the center of the piece. Sand* the leading edge round for both the
horizontal and vertical stabilizers. Next, key the vertical stabilizer to the top of the
horizontal as illustrated (second photo). Verify that the vertical stabilizer has been
installed perpendicular to the horizontal then glue.
(*you are more than welcome to aggressively sand, taper, and otherwise airfoil the
stabilizer assembly. Any compromise in thickness will compromise strength if this is
your first HLG you may wish to leave the stabilizer thickness at the stock 1/16”. For
those more experienced we have chosen the 1/16” stock to allow you adequate material
to airfoil these parts.)
2. Protect completed stabilizer assembly with wood finish spray in the same manner as
completed in Step 5 of Wing Assembly.
Final Assembly
1. Install the stabilizer assembly. Lightly sand the last two inches of the carbon fiber pop-up
tail where it will interface with stabilizer assembly. With the fuselage sides held
perpendicular to your work surface and the stabilizer assembly flat upon the same
surface. Slide the stabilizer under carbon boom using the etch marks in the top of the
stabilizer assembly to align boom on appropriate side of stabilizer. The boom should
contact both the horizontal and vertical components of the stabilizer assembly and stops
flush at the trailing edge of the horizontal stabilizer. Important! Place a scrap piece of
1/8” balsa under the left tip of the horizontal stabilizer to provide initial stabilizer tilt.
Secure stabilizer to boom using thin CA glue.
Lefties! place scrap 1/8” balsa under right
tip of stabilizer.
