9. Insert the control horn in the slit in the rudder
(or elevator).
10. Slide the control horn backplate over the end of
the control horn from the opposite side of the control
surface. Snap the backplate so the horn is held
tightly in position. Apply 2–3 drops of thin CA to the
backplate where it contacts the control horn to keep it
from accidentally coming loose in flight.
Before gluing the backplate in position, trim the
front edge of the backplate so it does not cause
binding in extreme throws. Temporarily snap the
backplate into position and mark the backplate
along the bevel with a felt tipped pin. Remove
the backplate and use side cutters to trim the
backplate. Use sandpaper to sand the backplate
to its to final shape before gluing it in position.
Always use threadlock on metal-to-metal fasteners
to prevent them from vibrating loose.
11. Use the radio system to center the rudder servo.
Center the rudder so it is aligned with the fin (or
the elevator to the stabilizer). Tighten the screw in
the pushrod connector to secure the pushrod wire.
Use side cutters to trim the excess length of wire that
extends beyond the connector as shown.
12. Repeat steps 1 through 11 to install the elevator
and associated hardware.
