Step 14
Use a hobby knife with a #11 blade to set the hinge gap.
You should just be able to slide the blade through the gap
between the elevator and stabilizer. Check that the elevator
can move freely without binding on the stabilizer.

Step 15
Use thin CA to saturate each of the three hinges on both
the top and bottom of the hinge. Allow the CA to fully cure
before proceeding.
Important: Do not use accelerator on the hinges.
The CA must be allowed to soak into the hinges.
Using accelerator will not allow the CA enough time to
correctly soak each hinge.

Step 16
Gently pull on the stabilizer and elevator to make sure each
of the hinges is secure. If not, reapply CA to the hinge that is
not secure.
Important: Sealing the hinge gap is necessary on
models that have large control surfaces and use large
control throws. Not sealing the hinge gap can lead to
flutter of the control surface and could result in the loss
of your aircraft. Make sure to seal the hinge gap at this
time.

Step 17
Use clear tape, clear covering or white covering to seal the
hinge gap on the elevator. Flex the elevator to open the gap
as far as possible when installing the hinge gap tape.
Note: We used colored tape to illustrate the position of
the hinge gap sealing tape.

Step 18
Flex the elevator through its range of motion a few dozen
times to break in the hinges and hinge gap tape.

Step 19
Repeat Steps 2 though 18 to prepare the remaining stabilizer
and elevator. Make sure you are making both a right and left
assembly when installing the control horn.
