11. Push a pin into the stab in front of the fin. Use a tape
measure or string to measure from the pin to one wing tip,
then check the distance from the pin to the other wing tip.
Adjust the wing as needed until both distances are equal.
❏
12. While holding the wing to the fuselage in this position
view the model from the front. Make sure that the wing is
aligned parallel with the stab. If it is not, lightly sand the high
side of the fuselage until the wing and stab are parallel.
❏
13. Glue the wing to the fuselage with 6-minute epoxy.
Hold the wing firmly in place until the epoxy has hardened.
❏
14. Use tape to assemble the die-cut cardboard jigs
supplied with the model. These jigs are used to establish the
correct dihedral and washout angles for the wing. There is a
small square marking the wing leading edge of each jig that
is not visible in the photo.
❏
15. Place the model upside down in the jigs. Make sure
that the leading edges of the jigs are at the leading edge of
the wing.
❏
16. Cut the wing struts from the 1/8” balsa wing strut
material. Make sure the model is firmly resting on the jigs as
you measure and cut each strut. Cut slots in the fuselage for
the rear struts at the molded marks. Use 6-minute epoxy to
glue the struts in place.
