98.
Lay a length of filament tape across the inner panels along the CG line (ballast tube
location) to form an “A” pattern with the previously laid filament tape.
99.
Apply strips of filament tape to the wing in a crisscrossing pattern as per illustration (same
as bottom surface).
100.
Locate the elevons you prepared
earlier and spray their bottom surface with
spray adhesive. Also spray the bottom
surface of the wing’s outer panels along
the foam trailing edge. Let dry for 5
minutes (or until aggressively tacky).
101.
Cut a length of filament tape in half
lengthways and cut into six 65mm (2 1/2”)
long strips.
102.
The balsa elevons are orientated so
that their narrower end is at the wing tip.
Position one of the elevons so that there is
a 2mm (3/32”) gap between its end and the
end of the fixed balsa trailing edge and
rotate it around so that it’s lying upside
down on top of the wing with its leading
edge in line with spruce drag spar. Use the
65mm (2 1/2”) long by 25mm (1”) wide
strips of filament tape to attach the balsa
elevon to the foam wing by wrapping
around pieces at either end and in the
middle of the elevon.
103.
Repeat this process for the second
elevon.
104.
Now rotate the elevons back
around so that they’re in their correct
position, butted up against the foam trailing edge with the 45 degree beveled opening at the
bottom.
105.
Spray the top of both balsa elevons and the rear portion of the adjoining foam sub
trailing edges with spray adhesive. Let dry for 5 minutes.
106.
Lay a strip of cross-weave filament tape down the entire hinge line of one elevon on
the top surface, positioned so that 1/3 of its width is on the elevon and 2/3 on the foam.
107.
Repeat for the second elevon.
108.
Spray the bottom surface of the wing along the wing’s center join line and each wing
tip with spray adhesive. Let dry for 5 minutes (or until aggressively tacky).
109.
Lay a strip of filament tape along the centre chord of the wing, overlapping the panel
join line by about 12mm (1/2”). Lay another strip towards the other side of the join line,
overlapping the first by about 25mm (1”) so the overlap is centered over the panel join line.
Split and wrap around at the leading edge and cut off flush with the trailing edge.
110.
Lay a strip of filament tape chord-wise (LE to TE) at each wing tip. Split and wrap
around at the leading edge and cut off flush at the trailing edge of the elevon.
111.
Spray the top surface of the wing’s center join line and each wing tip with spray
adhesive. Let dry for 5 minutes (or until aggressively tacky).
112.
Lay chord-wise strips of filament tape on the top surface at the wing’s center and
wing tips as per the bottom surface.
