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. Trim the aft edge of the sheet to overlap the center
spar halfway.
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. Gently lift
the aft edge of the sheet and quickly apply a bead of
medium (or thick) 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, the
center spar and the landing gear rail. Hold the sheet edge
down while the CA cures. Repeat on the other half of the
center section.
D 8. Use medium CA to glue the 3/32" x 1/4" balsa cap
strips to the top of the R-4 ribs. Glue 3/32" x 1/2" balsa cap
strips to the top of the R-5 ribs. The edge of the cap strips
on the R-5 ribs must be flush with the side of the ribs.
D 9. Sand the LE and TE sheeting flush with the R-5 ribs.
D 6. From the 2-3/8" wide center skins (cut in step 11, page
12) trim the skins to fit between the LE sheeting and the
sub TE from ribs R-2 to R-3. Glue them in place with
medium CA.
D 7. Use medium CA to glue previously cut 3/32" x 7/8" x 4"
balsa TE sheet to the TE. Refer to the cross-section shown
on the plans.
D 1. Sand the TE sheeting flush with the sub TE.
D 2. Cut a 4-1/2" long TE from one of the 1-1/8" x 24"
tapered ailerons (W17). From each of the two 1-1/8" x 6-7/8"
TE (W18), cut a 5-3/4" piece. The leftover 1-1/8" TE will be
used on the outer wing panels. Fit the 4-1/2" long TE on the
aft edge of the wing center section. Glue the TE to the aft
edge with 6-minute epoxy. Use masking tape to hold it in
position until the epoxy cures. Wipe off any epoxy that may
squeeze out with a paper towel. Bevel the ends of the TE to
match the angle at the center section. Trim the 5-3/4" TE to
fit the outboard sub TE and glue them in position with
medium CA.
