Sealing the Hinge Gaps
Although not mandatory, it is always a good practice to seal the
hinge gap of the aileron control surfaces. Sealing the hinge line
has several advantages. A sealed hinge line gives a greater con-
trol response for a given control deflection. It also offers more
precise, consistent control response and makes trimming the
aircraft during flight easier.
Step 9.
To seal the aileron hinge line, cut a piece of Clear
(GBG887) or White Goldberg UltraCote
®
(GBG870, not included)
approximately 3" wide by the length of your hinge line. Fold the
UltraCote
®
down the center with the adhesive side to the outside
making a sharp crease at the fold line.
Step 10.
Measure 3/8" from the folded crease out. Make
several marks along the length of the folded covering.
Step 11.
With the piece of covering still folded, use a hobby
knife with a sharp #11 blade and a straight edge to carefully cut
the entire length of the covering at the marks you made in the
previous step.
Step 12.
Remove the backing from the covering. Place the
folded crease into the center of the hinge line on the bottom of
the wing. Using a straight edge, hold one side of the covering in
place while ironing down the opposite side with a sealing iron.
Step 13.
Fully deflect the aileron in the up position. Place the
straight edge over the hinge line covering what you just ironed
down. With the straight edge placed firmly at the bottom of the
hinge line, iron down the covering while making sure the aileron
is fully deflected.
