Great Planes Super Sportster 40 MkII Kit - GPMA0205 - Manual (Page 12)

D D 4. Test fit a 3/32" x 2-1/2" x 25-1/4" balsa sheet along
the LE of the wing panel. Make sure that it fits flush. Wick
thin CA along the LE joint while holding the sheet in
position. Gently lift the aft edge of the sheet and quickly
apply a bead of medium CA to the top of each rib. Press
the sheet into contact with the ribs and hold it there until the
CA cures. Wick thin CA along the joint between the sheet
and the spar. Hold the sheet edge down while the CA cures.
D D 2. Glue the die-cut 3/16" balsa wing tip braces to the
top and bottom of the wing tips at the locations shown on
the plans. Refer to the wing plan, then shape the LE to
blend with the wing tip as shown in the photo.
D D 5. Finish cutting the access slots in W-1 for the wing
joiners as shown in the photo. Notice, there is a partially
die-cut line 1/8" behind the forward edge of the spars.
Finish cutting both ends of this line with a hobby knife. This
space is for the wing joiner doubler.
D D 6. At this stage, all remaining jig tabs should be trimmed
off and the rib edges sanded smooth.
D 7. Repeat steps 1-6 to sheet the top of the other
wing panel.
D D 3. Cut and install cap strips made from six 3/32"
x 1/4" x 24" balsa sticks onto the top and bottom of each
W-4 rib between the LE and TE sheeting. Do not cap the
W-3, W-2, and W-1 ribs as they will be fully sheeted later.
D D 4. Cut one 2" length from each of the two 1-1/8" x 24"
tapered balsa ailerons. Be sure to measure carefully and
make your cuts square. This is where a miter box comes in
handy. Use medium CA to glue both 2" wing tip TE in
position, to the TE'S and wing tips.
D 5. Repeat steps 1 -4 for the other wing panel.
D D 1. Center a die-cut 3/16" balsa wing tip on the
outboard W-4 rib between the spars. The forward edge
must be centered on the LE, and the aft end should align
with the TE. Glue the tip in position at a 90° angle to W-4.
Repeat for the other wing panel.
Note: Before actually using any glue for steps 1 - 4, test fit
the entire assembly to make sure the wing panels fit
properly. Although dihedral angle is not critical, when the
center section is on the building board, both wing tips
should be raised 1".
D 1. Insert 1" of the 1/8" x 2" hardwood alignment dowel
through the hole at the aft end of W-1. Glue it to the inside
of the TE with CA.
