• For aerodynamic reasons, if a
model’s two ailerons move the
same amount, some models will
yaw, or pull, toward the dropped
aileron. For example, if the modeler
gives left aileron inputs, the right
aileron drops and the left aileron
rises. If they move the same
amount, besides rolling to the left,
the model will also yaw to the right.
Aileron differential decreases the
amount of down travel for each
aileron without affecting the up
travel. By test flying and adjusting
this feature, the model can be
made to track straighter.
• Decrease the downward travel of
the twin aileron servos by
adjusting the aileron differential
pot. Doing so will help your model
to roll axially and not “barrel roll,”
turning toward the lowered aileron,
as shown in the sketch.
• If using the flaperons as flaps
AND differential, be sure to check
that you have sufficient aileron
controls even when you have full
flap throw. Decrease differential
until safe control is available.

Servo Connection
• Plug the aileron servo into slot 1.
• Plug the elevator servo into slot 2.
• Plug the throttle servo into slot 3.
• Plug the rudder servo into slot 4.
• Plug the gear servo (optional) into
slot 5.
• Plug the flap servo (optional) into
slot 6.

• Connector Connection:
Insert the receiver, servo, and
battery connectors fully and firmly.
• Receiver Vibration-proofing:
Vibration proof the receiver and
battery by wrapping them in
sponge rubber or similar material.
If the receiver may get wet,
waterproof it separately by
placing it in a plastic bag or
balloon. If the receiver is
subjected to strong vibration and
shock or gets wet, it may operate
erratically and cause a crash.
• Receiver Antenna:
Do not cut or bundle the receiver
antenna. Also, do not bundle the
antenna together with the servo
lead wires. Cutting or bundling the
receiver antenna will lower the
receiver sensitivity and shorten
the flight range and cause a
crash. Attach the antenna to the
top of the tail.
• Power Switch Installation:
When installing a receiver power
switch to the fuselage, cut a
rectangular hole somewhat larger
than the full stroke of the switch
knob and install the switch so it
moves smoothly from ON to OFF.
Always install the switch so it will not
come into direct contact with engine
oil, dust, etc. Generally, install the
switch to the fuselage on the side
opposite the muffler exhaust. Plug
the receiver battery into the black
battery lead on the switch
harness. Be sure the power
switch is “OFF.” Plug the red
switch harness lead into the “B”
battery slot on the receiver.
