17. Place the hinges in the elevator.

18. Carefully position the elevator so the hinges are
inserted into the stabilizer. Make sure that all the hinges get
installed, and that none get folded over accidentally. The
elevator will fit tightly against the stabilizer as shown. Use
the T-pins as handles to help in positioning the hinges.


19. Remove the T-pins from the hinges. Make sure the
elevator is pressed tightly against the stabilizer to eliminate
any hinge gap. Check that the tips of the elevator and
stabilizer are aligned.

20. Saturate each hinge using thin CA on both the
top and bottom of the hinge. Allow the CA to fully cure
before proceeding.
Note: Do not use CA accelerator on the
hinges. The CA must be allowed time to
soak into the hinge and surrounding wood
to provide the best bond for the hinge.

21. Once the CA has cured, gently pull on the stabilizer
and elevator to make sure the hinges are glued securely. If
any hinges are loose, apply more CA and check them again.

22. Flex the elevator through its range of motion a
number of times to break in the hinges. This will reduce the
load on the servo for those first flights.
