RadioLink AT9S Pro 10/12CH RC Transmitter with R9DS Receiver
Technical Highlights
Configurable 10/12-Channel Control
The AT9S Pro operates with ten channels by default and can be switched to twelve-channel operation through the transmitter system menu. This allows the radio to support both standard receiver configurations and compatible twelve-channel receivers.
3ms Synchronous Response
All active channels respond simultaneously within approximately 3ms, providing fast command transmission for aircraft, helicopters, multirotors, cars, boats and other compatible radio-controlled platforms.
DSSS and FHSS Hybrid Spread Spectrum
The RadioLink communication system combines DSSS and FHSS technologies with QPSK modulation and pseudo-random frequency hopping to improve interference resistance and maintain a stable control link.
Real-Time Telemetry
The transmitter can display receiver voltage and signal-strength information. Compatible external telemetry modules can add model battery voltage, GPS and flight-controller information.
Programmable Mix Control
Programmable mixing supports fixed-wing, glider, helicopter, multirotor, car and boat configurations. Available functions include V-tail, elevon, flaperon, throttle curve, pitch curve, gyro sensitivity and auxiliary-channel assignment.
External CRSF Module Compatibility
The multifunction trainer and simulator connector supports CRSF output for compatible TBS Crossfire transmitter modules, providing an additional long-range control-system option.

FAQ
What is the RadioLink AT9S Pro?
The RadioLink AT9S Pro is a programmable 2.4GHz RC transmitter designed for fixed-wing aircraft, gliders, helicopters, multirotors, cars, boats and compatible robotic platforms.
Does the AT9S Pro provide 10 or 12 channels?
The transmitter operates with ten channels by default. It can be changed to twelve-channel operation through the system menu when a compatible twelve-channel receiver is used.
Which receiver is included?
This package includes the RadioLink R9DS receiver. It provides nine channels in PWM mode or ten channels when SBUS and PWM outputs are used together.
What is the control range with the R9DS receiver?
The specified airborne control distance is up to 3400m in an unobstructed and interference-free environment. Actual range depends on antenna installation, local interference, terrain and regulations.
What is the response time?
The AT9S Pro provides approximately 3ms synchronous channel response for fast control transmission.
Which signal outputs does the R9DS support?
The R9DS supports conventional PWM output and simultaneous SBUS and PWM output. The operating mode can be changed using the receiver's ID SET button.
Does the AT9S Pro support telemetry?
Yes. It supports receiver-voltage and signal-strength telemetry. Compatible PRM telemetry modules can add model-battery voltage, GPS and flight-controller information.
Which model types are supported?
Supported model types include fixed-wing aircraft, gliders, helicopters, multirotors, cars, boats and robots.
Which batteries can power the transmitter?
The transmitter supports eight AA batteries or a compatible 2S–4S lithium battery within the specified operating-voltage range. Use a maximum 3S battery when a TBS Crossfire module is connected.
Can the Micro USB port charge the transmitter battery?
No. The Micro USB port is intended for firmware updates and must not be used as a battery-charging port.
Is the AT9S Pro compatible with TBS Crossfire?
Yes. A compatible TBS Crossfire transmitter module can be connected through the multifunction port after CRSF output is selected in the transmitter system settings.
Can the transmitter firmware be updated?
Yes. The AT9S Pro supports firmware updates through its Micro USB connection using compatible RadioLink firmware and update software.
B2B Procurement FAQ
What should buyers confirm before ordering?
Buyers should confirm the transmitter color, stick mode, channel configuration, receiver version, battery requirements, firmware version, package contents and destination-market radio regulations.
What information should be included in a bulk RFQ?
Include the required quantity, destination country, intended RC platform, preferred stick mode, receiver requirements, packaging specifications and requested delivery schedule.
Is the R9DS receiver included with every unit?
The package described here includes one R9DS receiver. Buyers should verify the final receiver and accessory configuration before confirming a bulk order.
Can alternative RadioLink receivers be supplied?
The AT9S Pro is compatible with several RadioLink receivers, including the R6DS, R6DSM, R10DS, R12DS and R12DSM. Availability depends on the selected package and supplier inventory.
Can the package include a transmitter battery?
Battery inclusion depends on the selected package, shipping method and destination regulations. Buyers should specify the required battery type and capacity during quotation.
Can packaging and labeling be customized?
Packaging, labels, manuals and accessory combinations may be customized depending on order quantity, supplier capability and applicable brand-authorization requirements.
