Section 4 – Sealing the Hinge Gaps
13
Step 2
Using a ruler, measure 1/2" from the folded crease
and mark two places with a felt-tipped pen.
Step 3
Using a sharp #11 blade and a straight edge,
carefully cut through both layers of UltraCote
®
covering at the 1/2" point marked in Step 2.
Step 4
Mark and cut the folded covering to an overall length
of 40". This piece will be inserted and ironed down
into the hinge bevel on the bottom of the aileron.
Step 5
Remove the backing from the UltraCote. Place
the folded crease side into the center of the hinge
line on the bottom of the wing. Using a straight edge
as shown, hold one side of the covering in place
while ironing down the opposite side with a sealing
iron. We recommend setting the iron temperature to
320° for this procedure.
Step 6
Fully deflect the aileron in the up position. Place the
straight edge over the hinge line covering that you
just ironed down in Step 5 with the edge of the
straight edge placed firmly at the bottom of the hinge
line as shown. Iron down this side of the covering,
making sure the aileron is fully deflected.
