Wing Assembly
NOTE: There are pictures of different planes in this manual, however, this plane’s
wings is assembled the same way.
1. It is much easier to install the twin control horns before installing the wing.
Locate the fiberglass aileron control horns, ball links, and associated bolts and
nylon-insert lock nuts. Use some fine sandpaper to roughen up the center areas of
the two control horns so that the glue adheres better. Using a sharp hobby knife cut
the covering away from the slots in the rudder and trial fit the control horns.
2. Mix up some 30 minute epoxy and coat the inside of the slots and the center of
the control horns. Hint: a scrap piece of 1/16” ply, tooth pick, or old hobby blade
can be used to coat the inside of the aileron slots. Slide the control horns in place
and make sure they are centered perfectly by using a ruler to measure between the
pivot holes and the hinge line. Wipe any excess glue off with isopropyl alcohol and
paper towels. Install the ball links, bolts and nuts into the holes to help assure
alignment of both control horns while the glue cures. Set aside until cured.
