❑ Remove the T-Pins and push the aileron up against the trailing edge. There should be no more than a 1/32" (.7mm) wide hinge
gap and the tip of the aileron should be even with the wing tip.
❑ Allow the C/A to dry for about 15 minutes, then pivot the aileron up and down several times to free up the hinges. Repeat the
previous procedures to hinge the second aileron to the other half of the wing, making sure to check the integrity of the hinges after
the C/A fully cures by gently pulling on the ailerons. The last thing you want is for a hinge to come loose during flight.
Step 2: hinGinG the eleVator
Step 3: hinGinG the rudder
❑ Slide one hinge into each of the four hinge slots in one aileron, making
sure that you push each hinge in up to the T-Pins.
IMPORTANT Don't glue the hinges into the aileron yet.
❑ Push the aileron and hinges into the corresponding four hinge slots in
the trailing edge of the wing.
❑ While holding the aileron tight against the trailing edge, pivot the aileron
down 45º and apply 5-6 drops of thin C/A to the exposed area of each hinge,
then turn the wing over and repeat for the other side of the hinges.
❑ Hinge the elevator to the stabilizer, using four hinges. Use the same
techniques that you used to hinge the ailerons to the wing.
IMPORTANT Make sure to check the integrity of the hinges after the
C/A fully cures.
❑ Hinge the rudder to the stabilizer and the fuselage, using three hinges.
Use the same techniques that you used to hinge the ailerons and the
elevator.
IMPORTANT Make sure to check the integrity of the hinges after the
C/A fully cures.
