WING DOWEL INSTALLATION
❏
1. Locate the two 5/16" x 2" [8 x 51mm] wing dowels. Test
fi t each dowel in the LE of the pre-drilled holes of the lower
wing. To help installation in the fuselage later, you may round
the tip of each dowel using sandpaper.
❏
2. Glue the dowels in the wing with epoxy. Install them so
that the top of the dowels are 5/16" [8mm] from the LE of the
wing. Note: If the dowels are longer than this, they will not
allow the lower wing to seat properly.

2. Trim the covering from the horizontal stabilizer slots in
the fuselage.

3. Slide the stab into the fuselage. Center the TE of the stab
so that the distance A=A. Make a mark at the top center of the
fi rewall and measure the distance from each stab tip. The stab
is correctly aligned when the distance A=A and B=B.
❏
4. Use a fi ne felt-tip pen to draw lines on the stab where
the stab meets the fuselage. Don’t forget to draw lines on
both the top and bottom of the stab.
❏
5. Lay a straightedge just a bit inboard of each line you
drew. Trim the covering along the edge of the straightedge.
Be very careful not to cut into the wood fi bers – a fresh hobby
knife blade should allow you to cut the covering when light
pressure is applied.

6. Slide the stab back into the fuselage and center it as
you did earlier. Level the stab so that it is parallel with the
wings. You may lightly sand the slots in the fuselage to adjust
the stab, but be careful not to make the slot too loose.
