It is a good idea to be sure that the aileron and
elevator hinge lines be sealed airtight Sealing the
hinge line has several advantages. A sealed hinge line
gives a greater control response for a given control
deflection. It also offers more precise, consistent
control response and makes trimming easier.
Sealing the aileron and elevator hinge line is highly
recommended. Failure to do so may cause control
surface flutter, resulting in a crash.
Step 1
Cut a piece of Clear UltraCote® for sealing the
ailerons to approximately 1" x 32". Fold the UltraCote
down the center with the adhesive side to the outside
making a sharp crease at the fold.
Step 2
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 3
Fully deflect the aileron in the up position. Place
the straight edge over the hinge line covering that
you just ironed down in Step 2 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.
Step 4
Repeat Steps 1 through 3 for the remaining aileron
hinge gap.
Step 5
Repeat Steps 1 through 3 for both elevator halves
using a 1" x 15" piece of clear covering.
