Binding Setup(Pair Procedure)
Fail-Safe Setup
Programming a receiver to recognize the code of only one specific transmitter.
Please note the setup must based on pair procedure well.
1. Turn the power switch on the transmitter & receiver to the ON position,the
LED on transmitter & receiver are continuously lit.
2. Move the stick to the position where you want the servo to move, press and
hold the receiver setup button for 2 second until the red LED on the receiver
flash slowly, then press and hold the receiver setup button again within 5
seconds (Note: after 5 seconds F/S setup will reset, you have to start over
at step one above) until the receiver LED is continuously lit, that's mean the
F/S function has been correctly set.
3.Verify if the failsafe function has been correctly set.Turn off the transmitter,
then check if the servos moves to the position that you set.
4. Any new binding (pair procedure) will clear the preset Fail-Safe.
1. Place the transmitter and the receiver close to each other (within one meter).
Turn the power switch on the transmitter to the ON position.
2. Press and hold the receiver setup button,then turn the power switch to the
ON position. The receiver LED will flash quickly. Release the setup button
after 1 second.
3. Press and hold the binding/PDM button on the transmitter for 1 second until
the green LED on the transmitter flash quickly then the LED on the transmi-
tter and receiver are continuously lit.
If you change transmitters or add a receiver, you must re-bind
before operating your model.
Range check the radio
A range check must be performed before the first flight of a new model.It is not
necessary to do a range check before every flight(but is not a bad idea to per-
form a range check before the first flight of each day).A range check is the final
opportunity to reveal any radio malfunctions,and to be certain the system has
adequate operational range.
1.We have installed a special “Power Down Mode” for doing a ground range
check.To activate the “Power Down Mode” please hold down the Bind key
and then turn the transmitter switch on.During this mode,the RF power is
reduced so the range test can be performed.When this mode is active the
green LED starts blinking.In addition,when the mode is activated the trans-
mitter gives users a warning with a beep sound every 1 seconds,and visual
indication.

The travel Range of the servos for the aileron or elevator can be changed at
any time by using the switch marked CH1 D/R or CH2 D/R，located above
the stick。With the switch in UP position，the channel’s servo will capable
of rotating through its full travel range(100%)。Moving the switch to the opp-
-osite position(DOWN) will limit the rotational range of the channel’s servo。
To adjust the D/R setting：
1.Swith the D/R switch to the DOWN position。
2.Adjust the trimmer located on the panel marked D/R CH1 or CH2，When
the trimmer is turned counter-clockwise，the rotational range will decreases
(Minimum 30%)，conversely，the trimmer is turned clockwise，the rotational
range will increases(Maximum 100%)。
CH1,CH2 DUAL RATE (D/R)
2.Walk away from the model while simultaneously operating the controls.Have
an assistant stand by the model and signal what the controls are doing to
confirm that they operate correctly.You should be able to walk approximately
30 - 50 paces from the model without losing control.
3.If everything operates correctly,return to the model.Set the transmitter in a
safe,yet accessible location so it will be within reach after starting the engine.
Be certain the throttle stick is all the way down,then start the engine.Perform
another range check with your assistant holding the plane and the engine
running at various speeds.If the servos jitter or move inadvertently,there may
be a problem.Do not fly the plane!Look for loose servo connections or binding
pushrods.Also be certain that the battery has been fully charged.
4.The “Power Down Mode” continues for 60 seconds and after that the power
will go back to the normal level.
To exit the “Power Down Mode” before the 60 seconds,turn the transmitter
switch on again.
5.NEVER start flying when the “Power Down Mode” is active.

The Elevon and V-tail mixing functions which can be turned on or off 。Ele-
-von control consists of a mixture between the elevator and aileron channels。
V-tail control consists of mixture between the elevator and rudder channels。
The default setting for all mixing will be off the GREEN LED should be on
steady。
To change the mix setting：
1.Switch off the TX power switch。
2.Press and hold CH2 and CH3 DOWN&HIGH trim button simultaneously。
3.Switch the TX power switch on，the GREEN LED should flash constantly
to indicate the mixing function has been turned on。
4.Repeat steps 1-3 to change the mixing function form Elevon on 、V-tail on
then off in sequence。
ELEVON & V-TAIL MIXING FUNCTIONS
This function changes the stick mode of transmitter。
Note：This will not change the throttle Ratchet etc。Those are mechanical
changes that must be performed by specific technician。
To change the MODE setting：
1.Switch off the TX power switch。
2.Press and hold CH1 and CH4 LEFT&RIGHT trim button simultaneously。
3.Switch the TX power switch on，the GREEN LED should flash and acco-
-mpanied by two audible tones indicate the MODE 2 function has been tur-
-ned on。Conversely the GREEN LED flash and accompanied by one audi-
-ble tone indicate the MODE 1 function has been turned on。
4.Repeat steps 1-3 to change the MODE function form MODE1 to MODE 2
in sequence。
5.Since TX power switch on then accompanied by one audible tone indicate
the MODE 1 function has been turned on，if accompanied by two audible
tones indicate the MODE 2 function has been turned on。
MODE 1、MODE 2 STICK SETTING

Intended for V-tail aircaft,V-tail mixing
allows the ruddervators to operate both
as rudders and elevators.The same as
the other mixes,V-tail mixing requires
that each ruddervator be operated by a
separate servo.
*If necessary,use the Servo Reversing
function to achieve the correct direction
of servo throws.
*If necessary,use the Servo Reversing
function to achieve the correct direction
of servo throws.
V-tail Mixing
Intended for tailless,“flying wing” models such
as delta wings and flying wings,elevon mixing
mixes channel 1 (aileron) to channel 2 (eleva
tor) allowing the elevons to operate in unison
(as elevators) or in opposition (as ailerons).
This function requires that each elevon be
operated by a separate servo.
Delta Wing Mixing
CH1 CH2
The direction of movement for any of the four channels can be reversed elec
tronically。
To change the direction of movement for each main channel：
1.Switch off the TX power switch。
2.Press and hold one specific trim button for the channel to be reversed。
CH1 right trim button for CH1 reversing.
CH2 down trim button for CH2 reversing.
CH3 high trim button for CH3 reversing.
CH4 right trim button for CH4 reversing.
3.Switch the TX power switch on，the GREEN LED should flash then steady
on to indicate the movement for that channel has been reversed。
4.Repeat steps 1-3 to reverse the direction of any other channel as needed。
