Aileron Servo Installation - Hangar 9 Katana 50 ARF Assembly Manual


Do not use CA accelerator when gluing the hinges.
Always allow the CA to soak into the hinge for the best
bond between the hinge and surrounding wood.

6. Remove the T-pins from the hinges and make sure
the aileron gap is as small as possible. Saturate the top and
bottom of each hinge using thin CA. Allow the CA to cure
before proceeding. Check that the hinges are secure by
gently pulling on the control surface. If not, apply thin CA to
any hinges that are not glued and recheck. Move the control
surface through its range of motion several times to break
in the hinges. This will reduce the initial load on the servo
during your first flights.

7. Repeat steps 2 through 6 to install the remaining
wing panel.
