D 3. Before using the L.E. and T.E. pieces, you must
determine which pieces are to be used for the right
wing panel. Here's how:
A- We have drawn red lines on the top of each
piece.
B - Notice that the pieces are notched on one
end, but not on the other. The notched end goes toward
the wing tip, and the end without a notch goes toward
the center of the wing.
C- Take one of the L.E. pieces and lay it on the
right wing panel plan with the red line up. If the
notched end is on the right side (at the tip) you have
the correct L E.
D- Do the same thing to determine which T.E.
piece to use.
D 4 Tape one of the 3/8" x 1/2" basswood spars to
the plan, with the right end of the spar lined up with
the tip. The excess spar length must extend past the
wing centerline.Apply tape in 3 places, between the
ribs, near the ends and in the middle.
D 5. Remove the 3/32" balsa wing ribs from the die
cut sheets and slide 12 ribs into place on the bottom
spar, using the plan to get them close to their proper
position DO NOT PUT A RIB AT THE CENTER-
LINE.
D 6. Insert the fronts of the ribs into the notches
in the balsa leading edge (L.E.).
D 7. Insert the backs of the ribs into the notches
in the balsa trailing edge (T.E.).
D 8. Adjust the position of the leading edge and
trailing edge left or right so they match the plan at
the right tip. Tape or pin them to the plan so they
don't move.
D 9. The tip rib should now match the plan exactly.
However, due to shrinkage or expansion of the paper,
the other ribs may not line up perfectly. That is OK,
because the notches in the L.E. and TE. are cut in
the right places. Before proceeding, make sure none
of the ribs are bowed (curved). If they are, straighten
them by sliding the center part right or left on the
spar.
D 10. Insert the top 3/8" x 1/2" spar into the top
notches in the ribs, so the right end is even with the
tip rib.
D 11. Insert two of the 3/16" x 3/16" basswood spars
into the small notches in the top of the ribs, so the
right ends are even with the tip rib.
D 12. Make sure that the ribs are all down onto the
plan and fully inserted into the notches in the L.E.
and T.E.
