step 1: hinging the aiLerons
IMPORTANT The control surfaces are held in place for packaging purposes using extra hinge material. Please discard this
material and use the included C/A-style hinges to hinge the control surfaces.
C/A-style hinges are used to hinge the control surfaces. These hinges are designed to be glued into place using thin C/A. Do not
glue these hinges into place using any other type of glue, such as thick C/A or epoxy. Use of any adhesive other than thin C/A
could result in failure of the hinges during flight.
For flutter-free control surfaces and crisp control response, it is imperative that the hinges be glued in properly. This is achieved
by having the correct 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 or loss of control of the airplane.
PRO TIP If you can't slide the hinges into the aileron up to the T-Pins, use a modeling knife with a #11 blade to cut the hinge
slots deeper.
