Note:About flying
While you are getting ready to fly,if you place your transmitter on the ground ,be sure that the
wind won’t tip it over. If it is knocked over, the throttle stick may be accidentally moved, causing the
engine to speed up. Also, damage to your transmitter may occur.
Other than 2.4GHz system: Before taxiing, be sure to extend the transmitter antenna to its full
length.collapsed antenna will reduce your flying range and cause a loss of control.It is a good idea to avoid
pointing the transmitter antenna directly at the model, since the signal is weakest in that direction.
In order to maintain complete control of your aircraft it is important that it remains visible at all times .
Flying behind large objects such as buildings, grain bins, etc. is not suggested. Doing so may result in the
reduction of the quality of the radio frequency link to the model.
2.4GHz system: DO not grasp the transmitter module’s antenna during flight.Doing so may degrade the
quality of the radio frequency transmission.
2.4GHz system: As with
the sides of the 9 shift transmitter module's antenna. As such, the antenna should not be pointed directly at
the model.If your flying style creates this situation,easily move the antenna to correct this situation.
Warning!!!
please don't fly in the rain! Rain or moisture may enter the transmitter internal through gaps in the antenna or
joystick flight and cause your flight to instability even out of control. If inevitable will fly in the wet weather
(such as game), please be sure to use plastic bags or waterproof cloth to cover your transmitter, please don't flight
if there is lightning.

1.2 RADIO INSTALLATION
1.2.1 Gudelines to mount the servos, receiver and battery
• Make certain the alignmen tab on the battery,switch and servo conectors is orient correctly and ‘key’ into
the corresponding notch in the receiver or connectors before plugging them in .When unplugging connectors,
never pull on the wires. Always pull on the plastic connector instead.
• Receiver’s Anenna: In generally receiver’s antenna is longer than remote control,don’t break or retract
it,otherwise shorten the control distance.The antenna must be kept away from conductive materials,such as
metal.please make distance test before flying.
• If your aileron servos are too far away to plug into the receiver,use an aileron extension cord to extend the
length.Avoid plugging multiple extensions together to abtain your desired length.If the distance is greater
7
than 50cm or high current draw servos are being used ,use heavy servo extensions.
• Receiver Vibration and Waterproofing: the receiver contains precision electronic part.Be sure to avoid
vibration,shock,and temperature extremes.For protection, wrap the receiver in foam rubber or other
vibration-absorbing materials. It is also a good idea to waterproof the receiver by placing it in a plastic bag
and securing the open end of the bag with a rubber band before wrapping it with foam rubber. If you
accidentally get moisture or fuel inside the receiver,you may experience intermittent operation or a crash. If
in doubt, please contact Radiolink aftersales or distributors f or service.
• Always mount the servos with the supplied r ubber grommets.Don’t over tighten the screws.No part of the
servo casing should contact the mounting rails,servo tray or any part of structure.Otherwise vibration will be
transmitted to the servo causing damage of servo.Note the small numbers (1,2,3,4) molded into each arm on
the servo arms.The number indicate how many degrees each arm is ‘off’ from 90 degrees to correct for
minute manufacturing deviations from servo to servo.
• To center the servos, connect them to receiver and turn on the transmitter and receiver.Center the trims
on the transmitter,then find the arm that will be perpendicular to the pushrod when placed on the servo.
• After the s ervos are intalled,operate each servo over its full travel and check that the pushords and
servo arms don’t bind or contact each other.Also make sure the controls do not require excess force to
operate. If there is an objectionable buzzing sound coming from a servo, there is probably too much
resistance in the control.Find and correct the problem.Even is there is no servo damage,excess battery drain
will result.
• Use the mouting plate from the receiver on/off switch as a template for the cutout and screw
holes,mount the switch on the side of the fuselage opposite the engine exhaust, and where it won’t be
inadvertently turned on or off during handling or storage.Be certain the switch moves without restriction and
‘snaps’from ON to OFF, and that the cutout allows full motion of t he switch in both directions.
• When intall the switch harness to the helicopter,please use the switch cover.Generally sandwich the
frame between the switch and switch cover and securely tighten the screws,Different models might require
different installations.If so ,please follow the model’s instruction manual
.
• To prevent the servo lead wires from being broken by vibration during flight,provide a slight amount
of slack or extra so that the wire sticks out slightly and fasten it at suitablr points.In addition,periodically
check the wire during daily maintenance.
The above listed receiver and channels is referred to the channel 1~9 of the receiver R9D, connect the
receiver with the related servo, you can control the servos by the correspondent switch.
To be clear, the servo connected with the receiver channel 1 is controlled by the radio aileron l ever; servo
connected with channel 2 is controlled by elevator lever; servo connected with channel 3 is controlled by
throttle stick; servo connected with channel 4 is controlled by the rudder lever. Channel 5~9 can be self-set
with the related switches by the menu AUX-CH, and the sub menu. For channel 9, the LED indicator on the
receiver flashes red for S-BUS signal and blue for PPM.

1.3.2 Model type
Under basic menu, use DIAL to select MODEL TYPE and enter by pressing PUSH. There are 6 different
type included in the system, HELICOPTER, AEROBASIC, GLID(1A+1F), GLID(2A+1F), GLID(2A+2F),
and AIRCRAFT, after model type is selected, press and hold PUSH for 1 second, when the word “are you
sure to change” displayed, model type is changed.
1.3.3 Bind
Each transmitter has an individually assigned, unique ID code. In order to start operation, the receiver must
be linked with the ID code of the transmitter with which it is being paired. Once the link is made, the ID
code is stored in the receiver and no further linking is necessary unless the receiver is to be used with another
transmitter. When you purchase another R6014FS, this procedure is necessary; otherwise the receiver will
not work.
1. Place the transmitter and the receiver close to each other within one (1) meter.
2. Turn on the transmitter.
3. Press and hold ID SET switch of the receiver one second, now the indicator LED will start blinking. It
will automatically find the nearest transmitter to bind, which is an outstanding feature for R9D receiver.
4. Test with servo to make sure the binding is finished.
1.3.4 S.BUS
Short press the ID SET switch two times within 1 second, the signal is changed from normal PWM to
S.BUS. The blue LED indicates the normal PWM and red S.BUS.
1.3.5 TransmitterDisplays & Buttons
When you first turn on your transmitter, a confirmation double beep sounds, and the screen shown below
appears. Before flying, or even starting the engine, be sure that the model type and name appearing on the
display matches the model that you are about to fly! If you are in the wrong model memory, servos may be
reversed, and travels and trims will be wrong, leading to an immediate crash.

Warning and error display
When the transmitter is powered on, warning or error may happen by the following probability:
1.Battery low voltage alarming
Lithium battery 2S-4S can fit for the transmitter, warning voltage can be self-set according to different
battery.
Setting step: power on the transmitter, press and hold MODE one second to enter basic menu, and press
PUSH to enter PARAMETER. Choose TX ALARM by DIAL and PUSH to change relative data. Suggested
min voltage is not less than 7.4V.
When the transmitter voltage is less than the setting voltage, it will beep till the transmitter is powered
off. Most important thing is to land your model plane when the transmitter alarms.
******WARNING!!!******
TXLOWPOWER!
2. Mixing alarm
When the t ransmitter alarms mixing, it means at least one mixed switch i s active. And when it is inactive,
warning will stop then. When the transmitter is powered on, in different model type, mixing switch is shown
as below:
HELI: throttle cut, throttle lock, speed up
If the warning continues even the related switch is set OFF, probably it is because some programs mixed by
one switch and status OFF reversed. Now you need to set mixing alarm again by DIAL.

MODEL SELECT
Totally there are 15 models stored in the system, followed by model name and plane type to use on tap, thus
you don’t need to set every time for different plane. MODEL NAME, MODEL TYPE and transmitter voltage.
Make sure that MODEL TYPE is accomplished with your plane type before flight. Or it will cause error in servo
and rudder.
COPY
Save the present data as another model type, it will be displayed by shadow area to differ from. When this
copy start, the object data will be fully covered including name, type and module type, and cannot recover.
Caution: when you save the present model type as another, all related data will be copied including the o riginal
16
model name. Accordingly, if you want to change the model type, the whole data need to reset, also for model
name. The first thing to copy is to change the model type or delete the original name and rename a new model to
avoid confusion.
Model Name
This is used to set the present model name. Name all model to identify each other, and fast select the model
type and reduce possible crash by wrong model type using.

channels 5 and 7. This allows you to utilize these 2 great functions while utilizing 5-channel receiver.
Caution: Changing AILE-2 only tells the system which servos to utilize if FLAPERON or AIL-DIF is
activated. You still must activate that function and complete its setup for details on twin aileron servos,
including usingAILE-2.
(Only for glider 1A+1F) if the channel 3 is set as the second aileron, the receiver F/S will become invalid.
Adjustable travel limit (ATL)
Makes the channel 3 TRIM LEVER (THROTTLE TRIM) effective only at low throttle, and disabling the
trim at high throttle. This prevents pushrod jamming due to idling trim changes. This function defaults to ON.
If you are not using channel 3 for throttle, you may want trim operation the same as on all other channels. To
do so, set ATL to OFF. If you need the ATL to be effective at the top of the stick instead of the bottom, reverse
the THR-REV setting. Note that this affects all models in the radio, not just the model you are currently
editing.

2.3.3 End Point of servo travel adjustment (END POINT, also called EPA)
The most flexible version of travel adjustment is available. It independently adjusts each end of each
individual servo’s travel, rather than one setting for the servo affecting both directions. Again, for CCPM
helicopters, be sure to see SWASH AFR prior to adjusting end points.
Adjustability:
• Can set each direction independently.
• Ranges from 0% (no servo movement at all) to 140%. At a 100% setting, the
Throw of the servo is approximately 40°for channels 1-4 and approximately 55°for channels 5-8.
• Reducing the percentage settings reduces the total servo throw in that direction.
Examples:
• Adjust the throttle high end to avoid binding at the carburetor, and low end to allow for proper carburetor
closure.
• END POINT may be adjusted to 0 to keep a servo from moving one direction, such as flaps not intended to
also operate as spoilers.
• Retract servos are not proportional. Changing END POINT will not adjust the servo.
END POINT adjusts only the individual servo. It will have no effect on any other servo that is operated in
conjunction with this servo via mix or preset programming such as FLAPERON, AILEVATOR, etc. This is so
that each individual servo can be carefully fine-turn to avoid binding and other conflicts. To adjust the total
travel of a function such as FLAPERON, make the adjustments in that function's controls. For CCPM
helicopters, adjust the total travel of the function, such as collective pitch, in SWASH AFR. Adjust the linkage
or the END POINT? It is nearly always best to adjust your linkages to get as close as possible prior to utilizing
END POINT. The higher the END POINT setting, the better position accuracy and the more servo power
available at nearly any position (except if using digital servos). Higher END POINT values also mean longer
travel time to reach the desired position, as you are utilizing more of the servo's total travel. (For example,
using 50% END POINT would give you only half the steps of servo travel, meaning every click of trim has
twice the effect and the servo gets there in half the time). end point (and moving the l inkage) = torque,
accuracy, but transit t ime t o get there.
• END POINT (instead of adjusting linkages) = travel time, but torque, accuracy.

The AT9 has digital trims which are different from conventional mechanical trim sliders. Each TRIM
LEVER is actually a two-direction switch. Each time the TRIM LEVER is pressed, the trim is changed a
selected amount. When you hold the TRIM LEVER, the trim speed will increase. The current trim position i s
graphically displayed on the start up screen. The TRIM submenu includes two functions that are used to
manage the trim options.
(1) Trim reset
RESET): Electronicallycenters the trims to their default values. Note that the
SUB-TRIM settings and the trim STEP rate are not reset by this command.
(2)
Trim step (STEP): changes the rate at which the trim moves when the TRIM LEVER is activated.
It may be set from 1 to 40 units, depending on the characteristics of the aircraft. Most ordinary
aircraft do well at about 2 to 10 units. Generally larger trim steps are for models with large
control throws or for first flights to ensure sufficient trim to properly correct the model. Smaller
trim steps are later used to allow very fine adjustments in flight.
HELI models only: OFFSET is available in the idle ups. If OFFSET is inhibited, adjustment of the TRIM
LEVERS will adjust the trims for all flight conditions. If OFFSET is active, then moving the trims within
any one condition will affect only that condition.

We recommend that you center the digital trims before making SUB-TRIM changes, and that you try to keep
all of the SUB-TRIM values as small as possible. Otherwise, when the SUB-TRIMs are large values, the
servo's range of travel is restricted on one side.
The recommended procedure is as follows:
• Measure and record the desired surface position;
• Zero out both the trims (TRIM RESET menu) and the SUB-TRIMs (this menu);
• Mount servo arms and linkages so that the control surface’s neutral is as correct as possible; and
• use a small amount of SUB-TRIM to make fine corrections.

2.3.6 Servo Reversing (REVERSE):
Changes the direction an individual servo responds to a CONTROL STICK motion.
Since channel 9 and 10 are switch only, its servo REVERSE is in the AUX-CH control screen with its
switch assignment. Be sure to read the section on SWASH AFR before reversing any servos.
Except with CCPM helicopters, always complete your servo reversing prior to any other programming. If
you use pre-built ACRO/ GLID functions that control multiple servos, such as FLAPERON or V-TAIL, it
may be confusing to tell whether the servo needs to be reversed or a setting in the function needs to be
reversed. See the instructions for each specialized function for f urther details.

2.3.7 Dual/triple rates and exponential (D/R,EXP)
Dual/Triple Rates: reduce/increase the servo travel by flipping a switch, or (ACROGLID) they can be
engaged by any stick position. Dual rates affect the control listed, such as aileron, not just a single (ex:
channel 1) servo. For example, adjusting aileron dual rate will affect both aileron servos when using
FLAPERON or AIL-DIF, and both aileron and elevator servos’ travel when using AILEVATOR or ELEVON
or a CCPM helicopter.
Activation:
• Any SWITCH, A-H. If you choose a 3-position switch, then that dual rate instantly becomes a triple rate.
• The glider programming offers you the choice of Condition. This option allows you to have a separate rate
for each of condition. (GLID)
• Stick position (ACROGLID). (Ex: On rudder you normally use only the center 3/4 of the stick
movement except for extreme maneuvers such as snaps/spins/stalls. As long as your RUDDER STICK does
not exceed 90% (ie. stall turn), the rudder goes to high rate's 90%, which is a MUCH higher amount of travel
than your low rate at 89%)
Adjustability:
22
• Range: 0 - 140% (0 setting would deactivate the control completely.) Initial value=100%
• Adjustable for each direction (ACRO/ GLID)
(ie. Up/down, left/right) (Ex: Most models fly upright without any elevator trim, but require some down
elevator when inverted just to maintain level flight. By increasing the down travel by the amount required to
hold the model inverted, the model now has equal travel available from level upright or level inverted.
Only if any stick is chosen by the item of "SW1", a switch can also be chosen by the item of "SW2."
When operated simultaneously, the switch operation has priority o
Exponential:
ver the stick operation. (ACRO)
Change the response curve of the servos relative to the stick position to make fly more pleasant. You can
make the servo movement less or more sensitive around neutral for rudder, aileron, elevator, and throttle
(except HELI type use THROTTLE CURVE instead). (ACRO type throttle EXP and THROTTLE CURVE
can not be activated simultaneously). Many models require a large amount of travel to perform their best
tricks.
However, without exponential, they are touchy around neutral, making them unpleasant to fly and making
small corrections very difficult. Additionally, by setting different exponentials for each rate, you can make
the effectiveness of small corrections similar in each rate, as in our example below:
The best way to understand exponential is to try it:
• Having made no changes yet in the D/R,EXP screen, move SWITCH D to DOWN (toward the AILERON
STICK).
•
Move SWITCH D up. Hold the AILERON STICK at 1/4 sticks and moves SWITCH D down.
• Notice how much less travel there is.
• Go to 3/4 stick and repeat. Notice how the travel is much closer, if not identical.
Adjustability:
• More sensitive around neutral. (Positive exponential)
• Less sensitive around neutral. (Negative exponential)
• Adjustable for each direction. (ACRO/GLID)
For throttle, exponential is applied at the low end to help nitro and gasoline engines have a linear throttle
response, so that each 1/4 stick increases engine RPM 25% of the available range. (In most engines this
ranges from 5-60%)
Special note for helicopters: Helicopter model types have just a single rate for each switch position
rather than a rate for each side of the servo's travel per switch position. Additionally, setting the D/R,EXP for
each switch position requires cursoring back to the No. setting and changing the switch position here. Just
flipping the switch does not affect the screen setting, alowing dual rates to be assigned with idle-up and other
features on certain switches, and does not require putting the model in that condition to make modifications.
Special note f or conditions: The helicopter and glider programming offers you the choice of Cond. This
option allows you to have a separate rate for each of the 3 controls automatically selected when changing
conditions, for a total of FIVE rates available. Simply change the switch choice to Cond. and then:
(HELI) press the CURSOR LEVER to toggle through the 5 conditions while setting the rates.
(GLID) activate t he corresponding condition to edit the rates.
