 2. Connect the aileron linkage to the hole in the
servo horn 7/16-inch (11mm) from the center of
the servo arm, and connect the flap linkage to the
hole in the servo horn 1/2-inch (13mm) from the
center of the arm.
 3. Remove the tape holding the flap and aileron in
position. Connect one clevis of the longer pushrod
to the outer hole of the aileron servo horn. The
remaining clevis connects to the aileron control
horn. Adjust the length of the linkage so the aileron
is centered when the servo is centered. Connect
one clevis of the shorter pushrod to the outer hole
of the flap servo arm and the other end to the
flap control horn. Adjust the length of the flap
linkage so when the flap servo is centered, the
flap is positioned as shown. Once the length of
the linkages has been adjusted, slide the tubing
over the forks of the clevises to keep them from
accidentally opening in flight. Use needle nose
pliers to tighten the nuts against the metal clevises.
 4. Set the switch at the transmitter to the UP flap
position. Adjust the flap system values of the
transmitter for the up position until the flap is aligned
with the aileron. This will be the UP flap position.
 5. Set the switch at the transmitter to the DOWN
flap position. Adjust the ATV at the transmitter for
the down position until the flap is 30mm below the
aileron. This will be the DOWN flap position.
Because there can be minor differences in control
horn and servo positions, do not connect the
linkage as described in steps 2 to the opposite
flap until you have checked the throws. Doing so
may cause the servo to bind in the UP position,
which could cause damage to the flap servo.
 6. Repeat steps 2 through 5 to prepare and install
the remaining flap and aileron linkages. Before
connecting the flap linkage, set the flap switch to
the UP flap position. Connect the linkage to the flap
servo and adjust its length until the flap is aligned
with the aileron. This will be the UP flap position.
You may have to fine-tune both flap linkages up
or down so they align at all three positions: up,
middle, and down. It is very important to use servo
arms positioned at the same angle on the splines of
the servo so the travel will match in all positions.
