Great Planes Super Sportster 40 MkII Kit - GPMA0205 - Manual (Page 11)

D D 1. Pin a wing panel back on the building board with the
landing gear rail pointing upward. Sight down the TE to
check for straightness-shim the ribs as necessary.
D D 2. Lightly sand the TE to remove any bumps. Use medium
CA to glue a 3/32" x 7/8" x 25-1/4" balsa TE sheet to the
TE. (Refer to the cross-section on the plans.) Hold a
straightedge across the sheeting while the CA cures to
keep the TE flat and straight.
D D 3. Use a razor saw or hobby knife to cut a 1/8" x 3/8"
slot through the W-1 rib between the spar and aft dowel
support as shown in the photo. Do not cut more than 3/8"
down. After the wing is sheeted, we will finish cutting out
the opening for the ply wing joiners.
D D 5. Test fit the LE sheet in position. When satisfied with
the fit, press the forward edge of the sheet tightly against
the LE and the ribs, then wick thin CA along the forward
seam. Wipe off any excess CA before it cures. Roll the
sheet into contact with the spar. Working from the center
toward the tip, wick thin CA between the sheet and the
spar.
D D 6. Wick CA around the seam between the sheeting
and the landing gear rail.
D D 7. Lift the wing off the building board. Then, while
holding it flat on your work surface, wick thin CA between
the ribs and the sheet from the inside of the wing. Add a
fillet of medium or thick CA along the inside of the LE.
D 8. Repeat steps 1-7 to sheet the bottom of the other
wing panel.
D D 4. Butt a 3/32" x 2-1/2" x 25-1/4" balsa sheet tightly
against the lip of the LE. Press down on the sheet with your
fingers in the vicinity of the landing gear rail to make an
impression of the landing gear rail on the inside of the
sheet. Turn the LE sheet over, then cut the access hole for
the landing gear rail using the impression mark as a guide.
D D 1. Pin the wing to the building board with the sheeted
side facing down. Trim and sand the jig tabs from the top of
the ribs (the sheeted side.) Sight down the TE to make sure
it's straight. Shim any low ribs.
D D 2. Glue a 3/32" x 7/8" x 25-1/4" balsa sheet to the TE
and ribs as you did with the bottom of the wing panel.
D D 3. Cut a 1/8" x 3/8" slot in W-1 between the spar and
the dowel support as you did in step #3 of the previous
section.
