Section 5: Installing the Elevators

Note

: You can combine the previous step

with the following step if you like. This will
hold the elevator in position while the epoxy
cures.

Step 6

Check to make sure the elevator moves freely. It
should not rub against the stabilizer at the tip. Check
to make sure the hinge gap between the elevator
and stabilizer is roughly 1/64". Apply thin CA to both
sides of the hinge. Make sure to saturate the hinge
and don’t use accelerator.

Step 7

Once the CA and epoxy have fully cured, gently
pull on the elevator and stab to make sure the
hinges are well glued. Flex the elevators a few times
to break in the hinges.
