Hook Up The Ailerons - GREAT PLANES SYNCRO Instruction Manual

Hook up the Ailerons

❏
1. If working on the glider wing (pictured), connect one of
the shorter Z-bend pushrods to the outer hole of the servo
arm on the servo in the right wing panel. Insert a screw-lock
connector into the bottom hole in the aileron control horn
and fi t the pushrod into the connector.
If working on the sport wing, connect one of the longer
Z-bend pushrods into the outer hole of the servo arm on
the servo in the right side of the wing. Insert a screw-lock
connector into the outer hole in the aileron control horn and
fi t the pushrod into the connector.
❏
2. Same as when you were fi tting the servo arms to the
servos, temporarily connect the aileron servo to the receiver
and power up the system so you can move the servo with
the transmitter. Holding the aileron centered, temporarily lock
the pushrod to the screw-lock connector with a 2mm screw.
❏
3. Use the control stick on the transmitter to move the
aileron servo. Make sure the servo is moving in the correct
direction; when you move the stick to the right the aileron
should defl ect toward the top of the wing (downward, since
we are working on the wing upside-down). If the aileron
does not respond in the correct direction, reverse the servo
direction in the transmitter.
❏
4. Once we've confi rmed that the servo direction is
correct, check the control throw as follows to make sure the
model responds correctly in the air—if the throw is too much
you will end up over-controlling it—if the throw is not enough
the model will respond too slowly.

Move the aileron stick all the way to the right. Measure how
far from center the trailing edge of the aileron moved. For the
glider wing, the aileron should move 3/8" [10mm] up and
3/8" [10mm] down. For the sport wing, the aileron should
move 5/16" [8mm] up and 5/16" [8mm] down. If the aileron
does not move the specifi ed distance, move the pushrod
to another hole in the servo arm or to another hole in the
aileron horn to increase or decrease the throw until you can
get it as close as possible (+/- 1/16" [1.5mm] is acceptable).
❏
5. Once you have the pushrods where you want them and
the control throw set, press a nylon retainer onto the screw-
lock connector securely holding it to the control horn—be
certain the retainer fi ts tightly and goes all the way on. If you
feel the retainer slipped on too easily, discard that retainer
and replace it with another—a couple of spare retainers are
included with this kit.
