Great Planes ElectriCub Kit - GPMA0156 - Manual (Page 15)

❏ 1. Cover the wing tip portions of the wing plan with wax
paper or Great Planes Plan Protector.
❏ ❏ 2. Assemble the wing tip from the die-cut 1/8" balsa
parts T-1, T-2, T-3 and T-4. There are two of each part (one
for each wing tip). Position the wing tip parts over the plan
and glue them together. Fill any gaps with medium CA, then
sand smooth.
❏ ❏ 3. With one of the wing panels flat on your building
table, glue the die-cut 1/16" balsa wing tip brace W-6 to the
end of the spars and tip rib W-4. The slot in W-6 must be
facing upward.
❏ ❏ 4. Trial fit the wing tip assembly against the end of the
LE and TE. Center the LE of the wing tip on the end of the
wing LE. The TE of the wing tip should rest on the building
table. Sand off the end of W-6 until it just touches the inside
edge of the wing tip.
❏ ❏ 5. With the wing tip centered on the LE and resting on
the table at the TE, glue the wing tip to the LE, TE and W-6.
❏ ❏ 6. Trial fit the die-cut 1/16" balsa rib W-5 in the notch in
W-6. Sand the rib if necessary for a good fit and glue in place.
❏ ❏ 7. Sand the front and rear of W-5 to blend into the
rib contour.
❏ ❏ 8. From a 1/4" x 1/4" x 13" balsa stick, cut and glue
wing tip filler blocks on the top and bottom of the wing tip
LE and on the top of the wing tip TE.
❏ ❏ 9. Use a sanding bar to blend the filler blocks into the
wing tip. Round the edges of the wing tip.
❏ 10. Go back to step 2 and assemble the other wing tip.
