28. With the gear in the rail, use a ballpoint pen to
mark the leading edge of the wing at both ends of the gear.
These marks will note the ends of a groove that will be cut
in the sheeting for the gear.
❏ ❏
29. Sheet the remaining open section of the bottom of
the wing panel with leftover 3/32" [2.4mm] balsa sheeting.
❏ ❏
30. Cut off the remaining portion of the spars, leading
edge and trailing edge so they are even, or nearly even with
R1. Do not cut off the leading edge at the tip. Sand the spars
and sheeting even with end ribs. Also sand the trailing edge
to match the shape of the ribs.
❏ ❏
31. Using the partially cut guide lines on R1, cut the
rest of the way through and remove the section of balsa
between the spars.
❏ ❏
32. Test fit, then glue together all the die-cut 3/32"
[2.4mm] balsa parts of the wing tip. Be certain to make a
right or a left tip depending on which wing panel is currently
under construction.
❏ ❏
33. Glue the completed wing tip assembly to the end
of the wing. Round the leading edge as shown in the photo
and on the plan. Add the tip bracing from leftover 1/4"
[6.4mm] balsa.
