❑ ❑ 5. Place the TE Strip with the beveled
and centerline-marked side down on a very flat
table. Glue a TE Jig Strip to the TE Strip. The jig
strip will keep the TE straight until the wing is
complete. Do not use excessive glue because it
will have to be sanded off later.
❑ ❑ 6. Glue the TE assembly to the wing
structure. The aft end of ribs W-2 through W-7
should align with the centerline you drew on the TE
Strip. Do not force the ribs to touch the TE Strip.
This will cause the TE to warp when you remove
the Jig later; just fill any slight gaps with glue.
❑ ❑ 7. Cut the die-cut 3/32” balsa Flap Tip
Rib in half along its centerline. Align half of the rib
over the plans and glue it in as shown in the photo.
❑ ❑ 8. Align the die-cut 3/32” balsa Flap Root
Rib over its location on the plan and glue it in with
CA+.
❑ ❑ 9. Trim off the ends of the TE Strip flush
with the W-1 rib and the Flap Tip Rib.
❑ ❑ 10. Use a razor saw and a single edge
razor blade to trim off the bottom half of ribs W-2
to W-7 (behind the TE at Flap). The bottom side
is the side opposite the jig tabs.
❑ ❑ 11. Use a T-bar sander to even up the ribs
inside the flap bay.
