INSTALLING THE AILERON CONTROL SYSTEM
Step 4.1
Consult
your radio instruction manual and
center
the
aileron servos using either
a
Y
connector
or a
comput-
er
radio
that
accomodates
the
use of
two
aileron servos.
Turn on the transmitter and then the receiver. Center
the
aileron
trim
lever on the transmitter. Remove the servo arm
mounting screws and servo
arms.
Step 4.2
Mount
the servo arms
back on the servos so that
the seruo arms are
parallel with
the
back edge of the wing.
Screw
the arms into place using the servo arm
mounting
screws supplied with the servos.
Step 4.3 Locate the two aileron control rods in the
hard-
ware bag (see 4A). Ensure the clevises are screwed
well
onto the threaded portion
of
the rod.
Rotate
and
tug
aggressively on the clevises and ensure that they are
not
loose on
the
rods.
Step 4,4Tape
the ailerons into their
neutral position so that
they are even with the trailing edge of the wing and
not
pointing either
up
or
down.
Step 4.5
Install the aileron control horns as illustrated
in
48
and ensure they align with
the servo arms.use 30
minute
epoxy

Step 4.6 Connect the aileron servo control rods
between
the
aileron control horns and the aileron seryo arms
as
shown in 4C.
Step
4.7
Carefully remove
the
masking tape holding
the
ailerons.
Step 4,8 Turn on your radio and activate the ailerons, using
the aileron stick and ensure that
a smooth full motion
can
be achieved.
Step 4.9 With the wing top side up and viewed from
the
back, ensure that moving the transmitter aileron stick to the
left
raises
the left
aileron
and lowers the right
aileron.
Movement of the stick
to the
left
will
roll
the aircraft to
the
left. (Counterclockwise roll of the wing when viewed
fr:om
the
back).
Step 4.10 With the wing top side up and viewed from
the
back, ensure that moving the transmitter aileron stick to the
right raises
the
right aileron
and
lowers
the left
aileron.
Movement of the stick to the right will roll the
aircraft
to
the
right. (Clockwise roll of the wing when viewed from
the
back).
