Stitch together the thrust duct by inserting the
tabs into the slots from the inside-out as shown
in the image below.
Stitch together the thrust duct
}}}}
Note; although it may seem the duct will come
together better if stitched from the outside-in
this should be avoided. It is critical the inside
surface of the thrust duct be as smooth as
possible in order to ensure undisturbed airflow
and optimal thrust. If the tabs are on the inside
of the thrust duct, they will create turbulence
and reduce the output of the power system.
Once the duct is bonded, it will attain a round
cross section.
}}}}
Flatten the overlap in the thrust duct along the
length of the duct using a piece of tape between
each of the tabs. Bond the edge of the thrust
duct using thin CA adhesive; press on the edge
to keep it down. Bond the tabs to the duct using
the same process. Work your way down the
entire length of the thrust duct.
Hold together the duct with tape and bond with
thin CA adhesive
Hold the tabs in place as the CA adhesive cures
}}}}
When the adhesive has cured, remove the tape
from the thrust duct. Complete the assembly by
running some adhesive along the duct edges
which were under the tape.
