D 25. After positioning the top wing in its proper location,
place alignment marks on the front bolt plates, ribs R-8, the
wing joiner and the LE. Remove the wing and use 30-minute
epoxy to glue ribs R-8 and the front bolt plates to the LE,
wing joiner and ribs R-7. Reinstall the top wing on the model
and check it for proper alignment before the epoxy cures.
Allow the epoxy to cure before removing the wing. Do not
Glue ribs R-9 and the aft bolt plates in at this time.
D 7. Drill a 5/32" hole through the top LE sheeting using
the hole through ribs R-8 as a guide.
D 1. Remove the wing and pin or weight it flat on your
building board. Make sure all the forward and aft jig tabs
are in contact with the building board.
D 8. Use a sharp hobby knife to enlarge the hole to 1/2" in
the LE sheeting only.
D 2. Test fit the 2" wide balsa LE wing sheet, cut during
assembly of the bottom wing, on the wing. Sand a slight
bevel on the front of the sheet. The aft edge of the sheet
should cover the forward half of the main spar. The root
end should cover to the center of rib R-10.
D 1. Mount the top wing on the fuse along with the struts.
D 3. Position the front of the LE sheet against the LE and
glue it in position with thin CA.
D 4. Carefully lift the sheet away from the ribs and apply a
bead of medium or thick CA to the top of the ribs. Working
quickly, pull the sheet back toward the main spar as you
press it down against the ribs and the main spar.
D 2. Secure the top wing to the cabane with two #6
washers and 6-32 lock nuts. Make sure the outer wing
struts are seated against the bottom wing. Measure the
distance from the fin to both wing tips. Adjust the bolt plates
and rib R-9 until the distance is equal.
D 5. Use thin CA to glue the sheet to the main spar.
D 6. Fit and glue the second LE sheet to the other wing
panel, following the same procedure.
D 3. After positioning the top wing in its proper location,
place alignment marks on the aft bolt plates, ribs R-9,
the wing joiner and the TE. Remove the wing and use
30-minute epoxy to glue ribs R-9 and the aft bolt plates to
the TE, wing joiner and ribs R-7. Reinstall the top wing on
the model and check it for proper alignment before the epoxy
cures. Allow the epoxy to cure before removing the wing.
