Step 5
Mix a small amount of 30-minute epoxy and apply it to both
the elevator joiner wire and the hole in the elevator half the
joiner wire fits into. Make sure not to get any epoxy where
it could accidentally glue the joiner wire to the stabilizer.
Reposition the elevator and make sure the tip of the elevator
aligns with the tip of the stabilizer.
Hint
: Use a paper towel and rubbing alcohol to remove
any excess epoxy before continuing.
Step 6
Repeat Steps 1 though 5 to attach the remaining elevator
half to the stabilizer,
Step 7
Remove the T-pins from the hinges. Check to make sure you
arebe able to achieve around 30–45 degrees of deflection for
aerobatic flight. Deflect the elevator (don’t move it away from
the stabilizer) and apply thin CA to the top and bottom of the
hinges. Use enough CA so it wicks into the hinge to bond the
hinge to the surrounding wood of the stabilizer and elevator.
Allow the CA to cure before proceeding.
Note
: Do not use a CA accelerator on the hinges. The
CA must be allowed to soak into the hinge naturally
to provide the best bond between the hinge and
surrounding wood.
Step 8
Gently attempt to separate the elevator and stabilizer to make
sure the hinges are properly glued. If not, apply additional
CA to secure loose hinges. Flex the elevator up and down
a few times to break-in the hinges to complete the hinging
process.
