The next step is to glue the sleeves
into the outer wings. Therefore sand
the inner surface of the outer wings
and the top and bottom edge of the
sleeves with rough sand paper. Trial
fit the wing and grind inside the wing
if you need to adjust the height for
perfect alignment between outer and
center wing. You can grind away
some of the carbon, up to 1 mm is
acceptable. The amount of carbon in
the outer wing is way overbuilt and
represents a huge safety margin. As
soon as the wing can be slid on
without force, wrap 3 layers of carbon
rovings on a length of 2-3 cm around
the sleeve. Then apply laminating
resin to the rovings. Use a little bit
milled fiber to thicken the resin which
is then applied on the joint surfaces.
Slide the wings right on, adjust them
perfectly to the surface of the center
wing and hold them in place with a
full width masking tape. Support the
wing tip, if necessary, or use a long
piece of masking tape to support it
towards the center wing. Let the resin
set over night.
Next you should create the permanent
fixture of the outer wing on the wing
fold spar. We recommend to use 2 M4
bolts per wing panel, this gives you
redundancy in regards to engine
vibrations, which can losen a bolt
eventually and you'll be glad to have
a second one...
While the outer wing panel is securely
taped in the down position to the
center wing, drill with dia. 3.3mm
through wing, sleeve and aluminum
wing fold. Be very careful not to
damage the cylinder rod of the wing
fold cylinder. You should use a depth
gauge (any brass tube over the drill bit
will do) or a very short drill bit to
prevent drilling too deep.
