SECTION 9: CONTROL SURFACE HINGING
STEP 1: HINGING THE AILERONS

✦
For flutter-free control surfaces, it is imperative that the hinges be glued in properly. This is achieved by
having a tight hinge gap and using plenty of thin C/A glue. Poor hinge installation can lead to control surface flutter which
can result in a catastrophic failure of the airframe. It's important to use a generous amount of epoxy to glue the torque
rods into the control surfaces, too. This will result in more positive control.
❑
Using a modeling knife, carefully cut away and remove the
covering material from over the precut slot in the root end of
one aileron.
☞
Notice that there is a predrilled hole in the slot to accept
the aileron torque rod wire.
❑
Slide one hinge into each hinge slot in the aileron, making
sure that you push each hinge in up to the T-pins.
Don't glue
the hinges into place yet.
❑
Push the aileron and its hinges into the hinge slots in the trailing edge of the wing, making sure that the torque rod wire
is firmly seated within the slot in the aileron. The aileron should be pushed firmly up against the trailing edge, so that there
is a minimal hinge gap (no more than 1/32" wide), and the ends of the aileron should not rub against the wing.

IMPORTANT

✦
✦
You may need to cut the slot in the aileron for the torque rod wire deeper so that the aileron can be
pushed forward enough to result in no more than a 1/32" wide hinge gap.
❑
Push two T-pins through the center of three C/A style aileron hinges. The T-pins will keep the hinges centered while
you are hinging the aileron.
