23. Use thin CA to glue the hinges. Make sure to check
and break them once the CA has fully cured.
24. At this time we recommend that you seal the hinge
gap between the elevator and stabilizer. Use either clear
covering or tape to seal the gap to prevent flutter of the
control surfaces during high-speed flight.
25. Thread the nylon torque rod horns on the threaded
ends of the torque rods. They will be flush with the top of
the threads as shown.
26. Place 2–3 drops of thin CA in each of the four holes
that will be used to mount the elevator servo. This will
harden the wood, making the screws more secure.
27. Remove the horn from the elevator servo. Install the
servo in the stabilizer hatch with the output facing away from
the elevators. Use the screws included with the servo to
secure it in the hatch. Make sure to install the grommets and
brass eyelets before securing the servo. Use a #1 Phillips
screwdriver to tighten the screws.
Note
: Although there are two elevator servo positions,
we DO NOT recommend using two servos. This will add
too much weight to the rear of the fuselage, making it
difficult to balance your model.
28. Use a pin vise and 5/64-inch (2mm) drill bit to
enlarge the hole in the servo horn. Use side cutters to
remove any unused arms so they don’t interfere with the
operation of the servo.
29. Slide a silicone clevis keeper on a clevis. Thread the
clevis on the split pushrod wire. Prepare the pushrod wire
with two clevises as shown. Attach the bend in the pushrod
wire to a hole in the servo horn that is 1/2-inch (13mm)
from the center of the horn.
