79.
It’s now time for covering. Spray the entire
underside of the glider with spray adhesive
and let dry for 5 minutes (or until
aggressively tacky).
80.
Bend over the ailerons and elevator and
cover the hinge gap area using 48mm or
50mm (2”) wide coloured polypropylene
covering tape. Then proceed with the rest
of the wing’s bottom surface starting with
the elevator. Let the tape overhang at the
trailing edge of the elevator, fixed trailing
edge pieces and ailerons (it will be
trimmed later) and tape right over the gaps
between the ailerons/elevator and fixed
trailing edge pieces (these will be cut free
later) but wrap around 25mm to 50mm (1”
to 2”) overhangs at the wing tips. Working
your way forward, lay down each strip of
tape spanwise (tip to tip) 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).
81.
Turn the wing over and spray the entire top
surface of the wing with spray adhesive
and let dry for 5 minutes (or until
aggressively tacky). Cover as per bottom surface.
82.
Using a straight edge (ruler) and sharp knife, trim off the tape that is overhanging the
trailing edge of the wing, elevator and ailerons. Leave about 3mm (1/8”) back from the
trailing edges so that the tape is sealed to each other (sticky side to sticky side).
83.
Lay strips of the coloured covering tape along the leading edge of each wing panel so that
half of the width is on the top surface and half on the bottom surface. Split and overlap the
tape at the panel joins and split and wrap around at the noses and wing tips.
84.
Cut free the elevator and ailerons and then wrap a piece of covering tape around each
exposed end of the ailerons, elevator and fixed trailing edges so that there is no balsa
exposed.
85.
Apply trims, stripes and/or decorations if desired.
LINKAGE HOOK-UP
86.
Draw a line on the ailerons and elevator straight back from each servo arm. Measure 7mm
(9/32”) back along this line from the elevator and aileron’s leading edges (hinge line) and
mark with a pen. This will be the position of the front of the base of the Dubro control
horns.
87.
Locate the two packs of Dubro control horns included in the kit. Separate the control horns
and their mounting back plates (you will have one spare). Hold the elevator’s control horn in
place and mark the position for the two mounting holes. Drill the holes and install the
control horn by screwing it onto its plastic back-plate, sandwiching the balsa elevator in-
between. Repeat for both ailerons’ control horns.
