Section 3 – Hinging and Sealing the Control Surfaces
Step 7
When fully cured, move each control surface
throughout its travel range several times to
break away any epoxy in the hinge. Be sure to
deflect the surface fully.
Section 4 – Sealing the Hinge Gaps
Step 1
Cut a piece of Clear UltraCote (not included) for
sealing the ailerons to approximately 3" x 42". Fold
the UltraCote down the center with the adhesive side
to the outside making a sharp crease at the fold.
Required Parts
• Wing panel (right and left)
• Aileron (left and right)
Required Tools and Adhesives
• Straight edge/ruler • Felt-tipped pen
• Scissors • Hobby knife w/#11 blade
• Clear UltraCote® (HANU964)
• Covering Iron (HAN101)
It’s imperative that the aileron and elevator hinge
lines be sealed airtight to prevent flutter. 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
mandatory. Failure to do so may cause control
surface flutter, resulting in a crash.
