Make certain that the control surfaces and the throttle
respond in the correct direction as shown in the diagram. If any
of the controls respond in the wrong direction, use the servo
reversing in the transmitter to reverse the servos connected to
those controls. Be certain the control surfaces have remained
centered. Adjust if necessary.
Check the Control Throws
The control throws are limited by the travel of the servos and the
mechanical set up of the pushrods. You can change the control
throw using the end-points or ATV feature of your radio, or you
can change the mechanical linkage to increase or decrease the
amount of control movement in relation to the amount of servo
movement. Keep in mind that changing the throws mechanically
is preferred to changing them using your radio’s end-point
adjustment. End points should be used to “
fi
ne-tune” to get the
proper throws.
Hold a ruler up to the control surface while it is at zero throw
(neutral). Move the control to the limit and measure the amount
of linear control throw. If your radio does not have dual rates, we
recommend setting the throws at the HIGH rate setting. NOTE:
The throws are measured at the widest part of the elevators,
rudder and ailerons.
If the control throws are too high, you can move the pushrod
connectors on the servo arms inward (toward the output shaft)
to decrease total travel.
These are the recommended control surface throws:

Balance the Model (C.G.)
❏
1.
At this stage the model should be in ready-to-
fl
y
condition with all of the systems in place including the motor,
propeller, spinner, radio system, battery, battery hatch, and
belly scoop. Place the battery in the battery compartment but
do not connect it.
Note:
The landing gear will have a slight
effect on the C.G. position.
❏
2.
Use a felt-tip pen or 1/8
″
[3mm]-wide tape to accurately
mark the C.G. on the top of the wing on both sides of the fuselage.
The C.G. is located 3
″
[76mm] back from the leading edge of
the wing at the wing root where the wing meets the fuselage.
