1. Slide the horizontal stabilizer into the slot at the rear of
the fuselage. Check the alignment using the sketch above
as a reference. Be careful not to flex the fuselage as you
make measurements.
❏
2. When you are satisfied with the alignment of the
stabilizer, glue it in place with low-temperature hot-melt glue
or shoe goo type adhesive.
“Welding” EPP with Hot-Melt Glue
When gluing EPP parts together with hot-melt glue, you can
use this technique to create a very strong bond if the parts
form an angle between them.
A. Run a small bead in the corner between the two parts.
B. Use the glue-gun tip to re-melt the glue bead, causing it
to penetrate into the joint and form into a fillet. The gun tip
will also slightly melt the foam, allowing the glue to fuse with
it somewhat, forming a
very strong joint.

3. Slide the wing into the cutout in the fuselage. Pull the
aileron servo lead strings up into the cockpit.
❏
4. Make sure the wing is centered and square in the
fuselage, and parallel with the stabilizer when viewed from
the front. Again, be careful not to flex the fuselage as you
make your measurements.
