Using a 5/64" drill bit, drill the holes through
the elevator.

RUDDER & ELEVATOR INSTALLATION
1.
!
Collect the following items.
(1) Fuselage/Tail Assembly
(2) Elevators
(1) Rudder
(12) Jet hinges
3.
!
Remove the pins in each hinge and, keeping
the elevator/stab assembly in position, apply
3 or 4 drops of thin CA to each hinge, on both
the top and bottom sides of the stab.
!
Allow ten minutes for the CA to cure before
flexing the elevator. Then install the second
elevator.
2.
!
Take four hinges and, as with the aileron
hinge installation, insert the hinge into the
elevator, using straight pins to ensure the
hinge stays centered between the stabilizer
and the elevator.
!
Slide the exposed side of the hinge into the
slots in the stab until the pins touch both the
stab and the elevator.
4.
!
When the elevators have cured, install the
hinges and mount the rudder, using the same
techniques used for the other hinged sur-
faces.
NOTE:
Before gluing, make sure the top of the rud-
der is even with the top of the fin.
