GREAT PLANES Sequence 1.20 Instruction Manual page 23

place. Mount the rudder servo and hook up the rudder using
the hardware shown—be certain to use threadlocker on all
the 4-40 nuts and don't forget to harden the servo mounting
screw holes with thin CA. NOTE: Stand-offs are used under
the ball links on the servo arm, but are not required on the
rudder horn.
❏
5. Pull on the elevators and inspect the hinges. Add thin
CA to any hinges that look dry.
11/16"
[18mm]
❏
6. If your elevator servos are higher than 11/16" [18mm]
from the bottom of the grommets to the bottom of the servo,
they will need to be shimmed up in order not to interfere with
the sheeting on the top of the horizontal stabilizers.
❏
7. Cut two more 4-40 pushrods to a length of 2" [50mm]
and solder on the threaded couplers to make the elevator
pushrods. Connect the elevators to the servos with the same
hardware as the ailerons—standoffs were not used under
the ball links on the servos, but were used on the elevator
horns. Be certain to use threadlocker on the nuts .
❏
8. Connect a 36" [910mm] servo extension to each
elevator servo wire and secure the connections with 1-1/2"
[40mm] pieces of heat shrink tubing.
❏
9. Glue a 1/8" [3.2mm] plastic dowel into each stab half.
❏
10. Fit both stabilizer halves to the fuselage with the
aluminum joiner tube as you guide the servo wires down
through the fuselage—a long piece of wire with a hook bent
on the end works for pulling the wires.
❏
11. Fasten the stabs to the fuselage with #2 x 3/8" [10mm]
Phillips screws, #2 lock washers and fl at washers. Be certain
to use threadlocker on the threads.
