CONTROL HORN INSTALLATION.
1) Locate the two nylon control horns, two
nylon control horn backplates and four
machine screws.
2) Position the elevator horn on the both
side of elevator. The clevis attach- ment holes
should be positioned over the hinge line.
6) Using C/A remover/debonder and a
paper towel, remove any excess C/A glue that
may have accumulated on the fuselage or in
the rudder hinge area.
Work the rudder up and down several
times to “work in” the hinges and check
for proper movement.
Note:
3) Using a 1.5mm drill bit and the control
horns as a guide, drill the mounting holes
through the elevator halves.

left side of the airplane. Mount the control horn
parallel with the horizontal stabilizer.

same method as with the elevator control
horns.

3) Connect the elevator and rudder servos
to your radio’s receiver and turn on the sys-
tem. Set the trim tabs on the transmitter to
neutral and center the servo arms. The eleva-
tor and rudder servo arms should be perpen-
dicular to the servos.
4) One at a time, hold the pushrods in po-
sition over the respective servos to check for
proper servo direction. If any servo turns in
the wrong direction, switch your radio’s re-
versing switches as necessary to achieve the
correct direction.
