Compatible Receivers

AT10II is a 12 channels transmitter, support 2.4G DSSS and FHSS spread spectrum working synchronously, 16 channels pseudo random frequency hopping.

AT10II sells with dual antenna receiver R12DS which support SBUS and PWM signal output simultaneous, signal coverage all around, never afraid of hilly terrain.

Besides R12DS, AT10II also compatible with Radiolink R6DS, R9DS, R10DS 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 working with SBUS or PPM signal.

R9DS, is a 9 channels receiver when working with PWM signal while it is a 10 channels receiver when working with SBUS signal.

Pay Attention: AT10II is default 12 channels, you have to setup AT10II to 10 channels first if you use receivers R6DS, R6DSM, R9DS and R10DS.

How to setup to 10 channels transmitter: power on your AT10II–Press Mode button one second to into BASIC MENU–into SYSTEM menu–change CH-SELECT from 12CH to 10CH.

Since Radiolink radio control systems are not open source, that Radiolink transmitters just compatible with Radiolink receivers and vice versa.

Radio Installation

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 after cares 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.

RSSI Testing

Power on transmitter and receiver, keep transmitter apart from receiver about 30 centimeters and the antenna straight.

Radiolink AT10II User Manual 4 - Radiolink AT10II User Manual

Into the parameter setup menu by press MODE one second, you can check the RSSI in RECEIVE menu.

The RSSI is 0 to 30dBm is normal when the transmitter is apart about 30 centimeters from the receiver, the signal is better the RSSI data is closer to 0.

Radiolink AT10II User Manual 3 - Radiolink AT10II User Manual

The above listed receiver and channels is referred to the channel 1~11 of the receiver R12DS, 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 5~11 can be self-set with the related switches by the menu AUX-CH, and the sub menu. For SBUS signal channel, is output by the 3 pin of 12 row.

Signal working modes:

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, 11 channels totally.

Radiolink AT10II User Manual 8 - Radiolink AT10II User Manual

(2) SBUS&PWM dual signal output working mode: BLUE/PURPLE led indicates SBUS&PWM signal output at the same time with 12 channels totally. SBUS signal channel(3 pin of row 11) outputs 12 channels of SBUS signal while PWM signal channels(3 pin from row 1 to row 10, i.e CH3 to CH12) output PWM signals with 12 channels in total. The actual channel quantity of PWM signal output depends on that of SBUS signal output used. Eg. If 4 channels of SBUS signal output used, then there are only 8 channels of PWM signal output left.

  1. Receiver Antenna Installment
  • Keep antennas as straight as possible and 90° as below, or the effective control range will reduce.

Radiolink AT10II User Manual 10 - Radiolink AT10II User Manual

  • Big 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.

Radiolink AT10II User Manual 5 - Radiolink AT10II User Manual

  • Antennas should be kept away from metal conductor and carbon fiber at least half inch away and no over bending.
  • Keep antennas away from motor, ESC or other possible interference sources.

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.

  1. Transmitter Antenna Installment
  • The 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.
  • Keep 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.
  • Never grip the antenna when flying as this degrades effective control range.

Installment of Antenna

Basic Setting of the Transmitter

Model Type

Under basic menu, use CURSOR 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.


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 R12DS, this procedure is necessary, otherwise the receiver will not work.

1. Put the transmitter and the receiver close to each other within 50 centimeters.

2. Power on AT10II and receiver R12DS. The RED LED will be on.

3. Turn on AT10II and it will automatically bind to 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.

Make sure servos connected with the receiver can be operated by the transmitter.


AT10II is default 12 channels and can be changed to 10 channels. In order to bind to non 12-channel receivers(R6DS,R6DSM,R9DS), channel quantity needs to change to 10 channels.

How to setup the channel quantity of the transmitter: power on AT10II–Long press MODE to enter BASIC MENU– Toggle the CURSOR to select and enter SYSTEM –change CH-SELECT from 12CH to 10CH.

Since RadioLink radio control systems are not open source, that RadioLink transmitters are ONLY compatible with RadioLink receivers.
