Specialnotefor2.4GHz FHSS radiosystemsetup
Receiver ’s Antenna installation
Since the 2.4GHz have different characteristics than that of the conventional frequencies,
please read this section carefully to enjoy safe flight with the 2.4GHz system.
The wave length of the 2.4GHz is much shorter than that of the conventional frequencies,
it is very susceptible to loss of signal which results inareceiving error.
To obtain the best results,please refer to the following instructions;
1. The antenna must be kept as straight as possible.
Otherwise it will reduce theeffective range.
2. The antenna should be
perpendicular to the fuselage.
Larger models can have largemetal objects that can
attenuate the RF signal. In this case the antenna should
be placed at side of the model. Then the best RF
signal condition is obtained at any flying attitude.
3. The a
ntenna must be kept away from conductive materials, such as metal and
carbon by at leastahalf inch.The coaxial part of the antennas does not need to
follow these guidelines, but do not bend it inasmall radius.
4. Keep the antenna away from the motor,ESC, and other noise sources as much
as possible.
*The main purpose of the photo
demonstrates how the antenna should
be placed. For actual installation the
receiver must be wrapped with a
sponge or placed with floating material
to protect it from vibration.
180°
The receiver contains precision electronic parts. It is the most delicate radio
component on-board the model and should be protected from vibration,
shock and temperature extremes.To protect the receiver,wrap it in R/C foam
rubber or other vibration-absorbing material. If appropriate, waterproof the
receiver by placing it inaplastic bag and closing the open end witharubber
band before wrapping it in foam. If moisture enters the receiver,intermittent
operation orafailure may result.Wrapping the receiver inaplastic bag also
protects it from fuel and exhaust residue which, in some models, can work its
way into the fuselage.
coaxial part

Transmitter antenna
1.The transmitter antenna is adjustable
so please make sure that the antenna is
never pointed directly at the model
when flying as this createsaweak signal
for the receiver.
2. Keep the antenna perpendicular to the
transmitter's face to createabetter RF
condition for the receiver.Ofcourse
this depends on how you hold the
transmitter,but in most cases, adjusting
the transmitter antenna so that it is perpendicular to the face will give thebest
results. Please adjust the transmitter antenna to the way you hold thetransmitter.
3. NEVER grip the antenna when flying as this degrades RF quality.

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 PDM 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.

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 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。
SERVO REVERSING

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%)。
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。
CH1,CH2 DUAL RATE (D/R)
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。
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
MODE 1、MODE 2 STICK SETTING
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

Transmitter Operation and Movement of Each Servo
Before making any adjustments, learn the operation of the transmitter and the
movement of each servo. (In the following descriptions, the transmitter is assumed
to be in the standby state.)
AILERON OPERATION
When the aileron stick is moved to the
right, the right aileron is raised and the left
aileron is lowered, relative to the direction
of flight, and the plane turns to the right.
When the aileron stick is moved to the left,
the ailerons move in the opposite direction.
To level the plane, the aileron stick must
be moved in the opposite direction.
When the aileron stick is tilted and held,
the plane will roll.
ELEVATOR OPERATION
When the elevator stick is pulled back, the
tail elevator is raised and the tail of the
plane is forced down, the air flow applied
to the wings is changed, the lifting force is
increased, and the plane climbs (UP opera-
tion). When the elevator stick is pushed
forward, the elevator is lowered, the tail of
the plane is forced up, the air flow applied
to the wings is changed, the lifting force is
decreased, and the plane dives (DOWN
operation).
THROTTLE OPERATION
When the throttle stick is pulled back, the
engine throttle lever arm moves to the
SLOW (low speed) side. When the throttle
stick is pushed forward, the throttle lever
arm moves to the HIGH (high speed) side.
RUDDER OPERATION
When the rudder stick is moved to the
right, the rudder moves to the right and the
nose points to the right, relative to the
direction of flight. When the rudder stick is
moved to the left, the rudder moves to the
left and the nose points to the left and the
direction of travel of the plane changes.

WARNING
Connector Connection
Insert the receiver,servo, and
battery connectors fully and
firmly.
If vibration, etc. causes aconnector to
work loose during flight, the plane may
crash.
Receiver Vi brationpr oong
/Waterpr oong
Vibrationproof the receiver by
wrapping it in sponge rubber or
some such material. If the re-
ceiver may get wet, waterproof
it by placing it in a plastic bag.
If the receiver is subjected to strong vibra-
tion and shock, or gets wet, it may operate
erroneously and causeacrash.
Receiver Antenna
Do not cut or bundle the re-
ceiver 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 causeacrash.
<Antenna installation>
For aircraft, attach the antenna to the topof
the tail.
Servo Thr ow
Operate each servo horn over
its full stroke and adjust so that
the pushrod does not bind or is
not too loose.
Unreasonable force applied to the servo
horn will adversely affect the servo and
drain the battery quickly.
Servo Installation
Install the servos to the servo
mount, etc. through arubber
grommet.Also install the servos
so that the servo case does not
directly touch the servo mount
or other parts of the fuselage.
Power Switch Installation
When installing areceiver power switch to the
fuselage, cut arectangular hole somewhat
larger than the full stroke of the switch knob
and install the switch so it moves smoothly
from ON to OFF.
Also install the switch where it will not come
into direct contact with engine oil, dust, etc.
Generally,install the switch to the fuselage at
the side opposite the muffler exhaust.
