Shape the stabilator leading and trailing edges with fine sandpaper (220
grit), sanding a round contour on the leading edge and a tapered contour
on the trailing edge. Then glue the left stabilator onto the carbon rod with
5 minute epoxy, making sure the carbon tube is centered in the fuselage
first.
After the glue cures, glue on the right stabilator, making sure it is aligned
with the left stabilator and that both stabilators are flush with the fuselage
sides. Once the glue is cured, check the stabilator pivoting and make sure
it turns freely. Touch up sand the fuselage sides and/or stabilator ends as
required so that they don’t rub.

Now install the elevator servo. The servo should fit very tightly, and 3M
Satin tape (or glue) can be used to hold it in place.
Make a pushrod from 1/32” music wire and install it (Z-bends are
recommended at both ends).
After the pushrod is installed, get everything aligned:
•
Center the servo arm vertically
•
Center the stabilator control horn vertically
•
Make sure the stabilators are flush with the fuselage sides and at
neutral (0 degrees deflection)
•
Make sure the end stop and control horn are flush against the
aluminum tube bearings (so that there’s no side-to-side motion)
After all of these are aligned, glue the control horn and end stop to the
carbon rod with CA glue and accelerator.
