81.
It’s now time for covering.
82.
Spray the entire underside of the glider
with spray adhesive and let dry for 5 to 10
minutes (or until aggressively tacky).
83.
Bend over the elevons and cover the hinge
gap area using 48mm (2”) wide coloured
covering tape.
84.
Now start laying down strips of the
covering tape on the wing’s bottom surface
starting at the trailing edge. Let the tape
overhang at the trailing edge (it will be
trimmed later) and tape right over the gaps
between the elevons and fixed trailing edge
(these will be cut free later). Working your
way forwards, lay down each strip of tape
from the middle of the wing out to the
wing tips, overlapping the previous one by
5mm to 10mm (3/16” to 3/8”). Don’t
worry about overlapping the leading edge
of the wing, just trim off flush for now (it
will be covered later).
85.
Turn the wing over and spray the entire top
surface of the wing with spray adhesive
and let dry for 5 to 10 minutes (or until
aggressively tacky). Cover as per bottom
surface.
86.
Using a straight edge (ruler) and sharp
knife, trim off the tape that is overhanging
the trailing edge of the wing and elevons.
Leave about 3mm (1/8”) back from the
trailing edges so that the tape is sealed to
each other (sticky side to sticky side).
87.
Cut the elevons free and then wrap a piece
of covering tape around each exposed end
of the elevons and fixed trailing edges so
that there is no balsa exposed.
LINKAGE HOOK-UP
88.
Draw a line on the elevons straight back from each servo arm. The line should be about
25mm (1”) from the end of the elevons. Measure 8mm (5/16”) back (towards TE) along this
line from the elevons’ leading edge (hinge-line) and mark. This will be the position of the
front of the base of the Dubro control horns.
89.
Locate the package of Dubro control horns included in the kit. Separate the control horns
and their mounting back plates. Hold a control horn in place and mark the position for the
two holes. Drill the holes and install the control horns by screwing them onto their plastic
back-plate, sandwiching the balsa elevon in-between. Repeat for the second control horn.
