Hinge Slots
Fugly uses “CA Hinges”. These are a rectangular piece of fibrous plastic film which is inserted into slots
cut into both sides without glue. Once in place, thin super-glue is “wicked” into the hinge material, which
saturates both the hinge and the wood in contact with it. Once set (which happens in seconds) it forms a
flexible but very strong hinge.
Carefully cut the slots for the hinges
with a scalpel. Cut them into the
control surface first, then cut the slots
in the wing and tail to ensure they line
up.
The hinges should be a firm fit into
the slot - too tight and they will bend
instead of sliding in, too loose and the
glue won’t form a strong bond. Keep
testing with a hinge as you open up the
slots.
Elevator Joiner
Elevator Joiner Wire, Elevators
Drill 2mm holes into the elevators
to take the ends of the wire joiner.
Carefully cut a channel into the
bevelled edge of the elevators so
that the joiner is flush.
When fitting the joiner, ensure that the
hinge slots line up, and that the ends of
the elevators line up with the ends of the
tailplane before drilling.
