SECTION 6: AILERON HINGING
STEP 1: HINGING THE AILERONS

Important Information About the Aileron Hinges Included with Your Big Bee ARF

The hinges are not glued into place from the factory. You must glue them into place. The ailerons are hinged using plastic steel-
pinned hinges that are designed to be glued into place with epoxy. Do not use thin C/A to glue these hinges into place.
For flutter-free control surfaces and crisp control response, it is imperative that the hinges be glued in properly. This is achieved
by having a tight hinge gap (no more than 1/32" wide) and using plenty of glue.
❑
Using 220 grit sandpaper with a sanding block, lightly sand both sides
of the mounting tabs on each of the eight hinges, to roughen the smooth
plastic surfaces.

You must roughen the plastic so that the epoxy will
stick to it. If you don't roughen the plastic, the hinge(s) may pull out
during flight.
❑
Slide three of the hinges into one aileron and center them in the
middle of the hinge slots.
❑
Using a modeling knife, carefully cut a shallow bevel in the aileron
directly above and below each hinge, so that the hinge pivot point can
be recessed into the leading edge.

The bevel should be deep enough so that when
you push the hinge in further, the pivot point of the hinge will be
flush with the leading edge of the aileron. This will ensure that there
will be little to no hinge gap when the aileron is hinged to the wing.
