1.1.3 Compatible Receivers
AT9S Pro is a 10 channels transmitter, support 2.4G DSSS and FHSS dual hybrid spread spectrum, 16
channels pseudo random frequency hopping.
AT9S Pro sells with receiver R9DS.
R9DS is a 9 channels receiver when working with PWM signal(red LED), it will a 10 channels receiver when
working with S-BUS signal(purple/blue LED).
Besides R9DS, AT9S Pro is also compatible with Radiolink R6DS, R10DS, R12DS and super mini 10
channels receiver R6DSM and 12 channels mini dual antenna receiver R12DSM.
R6DS, is a 6 channels receiver when working with PWM signal while it is a 10 channels receiver when

Radiolink Electronic Ltd

working with SBUS or PPM signal.
R12DS, is a 11 channels receiver when working with PWM signal while it is a 12 channels receiver when
working with SBUS signal.
Note AT9S Pro is default 10 channels, you can upgrade it to 12 channels with USB cable. You have to setup
AT9S Pro to 12 channels first if you use 12 channels receivers R12DS or R12DSM while you have to setup
AT9S Pro back to 10 channels when you use 10 channels receiver R6DS, R6DSM and R10DS.
To setup to 12 channels: power on your AT9S Pro--Press Mode button one second into BASIC MENU--into
SYSTEM menu--change CH-SELECT from 10CH to 12CH.
Since Radiolink radio control systems are not open source, that Radiolink transmitters just compatible with
Radiolink receivers and vice versa.
1.1.4 Connection with TBS Crossfire TX
①Power on the transmitter- Long press the Mode key to enter the BASIC MENU->Rotate the Scroll
Dial to highlight the SYSTEM option and depress the Enter key->Select the OUT and change the output as
CRSF
Note There are totally three signal output SBUS/PPM/CRSF
②Connect the TBS Crossfire transmitter to the AT9S Pro with the cable(packed inside the box)
The detailed steps please refer to the video tutorial https://youtu.be/g_mfHdeEQCo
Note The compatibility function with TBS Crossfire TX is only available in AT9S Pro, which CANNOT be
upgraded from AT9S Pro directly.
1.1.5 RSSI testing
Power on transmitter and receiver, keep transmitter apart from receiver about 30 centimeters and both
antennas straight.
Enter the parameter setup menu by press MODE one second, you can check the RSSI in RECEIVE.
The RSSI is 0 to 30dBm is normal when the transmitter is apart about 30 centimeters from the receiver, the
signal is more better the RSSI data is more close to 0.

1.2 RADIO INSTALLATION
1.2.1 Guidelines to mount the servos, receiver and battery
•Make certain the alignment tab on the battery, switch and servo connectors 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 Antenna: 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 obtain your desired length. If the distance is greater
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 aftercares or distributors for service.
•Always mount the servos with the supplied rubber 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, and 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 servos are installed, operate each servo over its full
travel and check that the pushrods 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 mounting 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 the switch in
both directions.
•When install 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 suitable 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 R9DS, 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 lever; 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 blue for S-BUS signal and red for PWM.
1.2.3 Installment of antenna
Installment of antenna
1. Receiver Antenna Installment
①Keep antennas as straight as possible, or the effective control range will reduce.
②Big models may contain metal parts that influence signal emission. In this case, antennas should be
positioned at both sides of the model to ensure the best signal status in all circumstances.
③Antennas should be kept away from metal conductor and carbon fiber at least half inch away and no
over bending.
④Keep antennas away from motor, ESC or other possible interference sources.
⑤Press and hold the ID SET for more than one second and receivers will start to work with the RED
LED on.
Note Receiver contains some electronic components of high-precision. Be careful to avoid strong vibration
and high temperature.
When all the above steps are complete, please turn off the transmitter and repower on to test if the receiver is
correctly connected with it.
2. Transmitter Antenna Installment
①The transmitter antenna is adjustable so please make sure that the antenna never points directly
at the model when flying as this may possibly decrease the receiver signal.
②Keep the antenna perpendicular to the transmitter to optimize the receiver performance. It also
depends on how you hold the transmitter. But in most cases, adjusting the antenna with perpendicular
position to the transmitter surface will achieve the best result. Please adjust the transmitter antenna
according to the way you hold the transmitter.
③Never grip the antenna when flying as this degrades= effective control range..
1.3 RADIO BASIC SETTING
1.3.1 Basic setting of the transmitter
1. Display language: can be selected the display language of the function name, etc. in each function menu.
The screen reads "LANGUAGE". Change this to the desired language.
2. Stick Mode: The screen reads "STK-MODE". Change this to the correct mode. Note that this will NOT
change the throttle and elevator ratchets, etc. Those are mechanical changes that must be done by a
service center.
3. RF Mode: the LED indicator will become solid green when RF Mode is active.
4. Adjusting Display Contrast: To adjust the display contrast, from the home menu press and hold the END

BUTTON. Turn the DIAL while still holding the END BUTTON: clockwise to brighten and
counterclockwise to darken the display.
5. User name setting: user name can be set by DIAL and PUSH with letters and numbers.
6. Alarming voltage:
Transmitter: preset 8.6V, can be self-set
Receiver: preset 4.0V, can be self-set
Ext: preset 10.1V, can be self-set
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
MULTIROTOR, 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 Binding
Each transmitter has an individually assigned, unique ID code. Receiver should bind to transmitter before
starting operation. Once binding is complete, the ID code will be stored in the receiver and no further binding
is necessary unless the receiver is used with another transmitter. When you purchase a new R9DS, this
procedure is necessary; otherwise the receiver will not work.
1. Put the transmitter and the receiver close to each other about 50 centimeters.
2. Power on AT9S Pro and receiver R9DS. The RED LED will be on.
3. Turn on AT9S Pro and it will automatically bind with the closest receiver.
4. There is a black binding button (ID SET) on the side of receiver. Press the button for more than 1 second
and release, the RED (by default, could be Purple for SBUS&PWM signal output) LED will flash, meaning
binding process is ongoing.
5. When the LED stops flashing and is always on , binding is complete.
6. Make sure servos connected with the receiver can be operated by the transmitter.
1.3.4 Two signal working modes of R9DS:
There are two signal working modes, PWM and SBUS&PWM signal output. Short press ID SET twice within
1s, the working mode will change.The RED led indicates the PWM output and BLUE/PURPLE led indicates
SBUS signal.
(1) PWM signal output working mode：RED led indicates PWM signal output, 9 channels totally

(2) SBUS&PWM dual signal output working mode: blue/purple LED indicates SBUS&PWM signal output at
the same time with 10 channels totally. CH9 outputs SBUS signal while the original CH1 outputs CH3 PWM
signal and original CH2 to CH6 output CH6 to CH10 PWM signal at the same time.
1.3.5 Transmitter Displays & 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.
2. Mixing alarm
When the transmitter alarms mixing, it means at least one mixed switch
is 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:
ACRO: throttle cut, idle down, snap roll, air brake
GLID: butterfly, condition
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.
PART 2. BASIC FUNCTION OF AIRPLANE
Pay attention that the (BASIC) menu is suitable for all type models (airplane, helicopter, glider, MULTIROTOR,
cars and boats). The motor cut will be introduced in Glider (Basic) Menu, except Idle down &Throttle cut.
Helicopter Basic Menu include some extra function (swashplate tilting, throttle and pitch curves and the tail
rotor anti torque mixing under normal flight model) will be discussed in Helicopter section.
