Step 1: Hinging the Ailerons
For flutter-free control surfaces it is imperative that the hinges be glued in properly. This includes both having a tight
hinge gap and using plenty of thin C/A glue.
Each aileron is hinged using four hinges.
Working with one aileron and wing panel for now, slide the aileron and its hinges into the precut hinge slots in the
trailing edge of the wing panel, making sure that the leading edge of the aileron is pushed firmly up against the trailing edge
of the wing panel and that the outer end of the aileron does not rub against the wing tip.

Center each hinge within its precut slot in both ailerons.
If you can't push the hinge in halfway, carefully cut the slot
deeper using a modeling knife.
Carefully glue each hinge into place using 5-6 drops of
thin C/A on each side of the hinge. Do not use thick C/A or
epoxy. Use only thin C/A for proper adhesion.
If any C/A gets onto the aileron, it can be removed
promptly using a paper towel soaked with a small quantity of
C/A Debonder.
While holding the aileron tight against the wing panel,
pivot the aileron down about 45º and apply 5-6 drops of thin
C/A to the exposed area of each hinge. Turn the wing panel
over and repeat for the other side of the hinges.
Remove any C/A that may run down the hinge line using
C/A Debonder.
Allow the C/A to dry for about 15 minutes, then pivot the
aileron up and down to free up the hinges.
