DSSS and FHSS Hybrid Spread Spectrum


DSSS* and FHSS* hybrid spread spectrum, 16-channel pseudo-random frequency hopping, and QPSK* modulation ensure excellent anti-interference performance, providing a highly constant and stable transmission signal on all 12 channels of AT9S Pro.

The actual control distance of AT9S Pro is 3400 meters of air.

* Direct Sequence Spread Spectrum transmissions multiply the data by a "noise" signal. This noise signal is a pseudorandom sequence of 1 and -1 at a frequency higher than that of the original signal.

* Frequency Hopping Spread Spectrum offers three main advantages: signals are highly resistant to narrowband interference, are difficult to intercept, and can share a frequency band with many types of conventional transmissions with minimal interference.

CRSF Protocol Supported


Using proprietary communication technology of RadioLink, DSSS and FHSS hybrid spread spectrum,

as a foundation, we have added the CRSF* protocol from the TBS.

AT9S Pro is compatible with TBS Crossfire.

CRSF is a proprietary TBS communication protocol between the Crossfire and R/C and Flight Control. It provides ultra-low latency with incredible bandwidth (3x faster, 6x more data than any comparable protocol).

Top Configuration | 3ms Response


The MCU (microcontroller unit) is STM32F103VET6 (32bits ARM 72MH Basic Frequency, 512K Flash Capacity, 12bits ADC).

TI CC2533 from the US is used as the wireless chip.

QPSK modulation helps ensure stable control.

4096 Section Precision

High-quality Components and Efficient Circuit Design Ensures Maximum Precision


All-new 4096 IC circuit minimizes servo jitter. Optimal PCB layout design and the same noble potentiometer of FUTABA produce a very stable signal output, with maximum servo output jitter of just 1.84us and typical jitter of 0.25us, it delivers 6 times the stability of competing products, making all servos rock-solid. This provides superior performance for high-precision 3D helicopter aerobatics or racing drone extreme aggressive freestyle flying

SBUS, PPM, PWM, and CRSF Signals Support


With the DSSS&FHSS protocol, SBUS, PPM, and PWM can operate simultaneously for seamless user control.

With the CRSF protocol, TBS Crossfire needs to bind to the BLACKSHEEP receiver.

A 9/10-channel receiver R9DS is packed with AT9S Pro. It is the receiver with SBUS and PWM signal output.

AT9S Pro is also compatible with R12DS, R12DSE, R12DSM, R6DSM, and R6DS receivers of RadioLink.

Compatible receivers cover a wide range of aircraft to meet the most demanding applications of customers.

R12DSE: A 12-channel receiver with SBUS or CRSF signal output, it is suggested to use for a racing drone or multicopter.

R12DS: A 12-channel receiver with SBUS and PWM signals output, it is suggested to use for a helicopter, fixed-wing, multicopter, car, boat, or robot.

R6DS: A 6/10-channel receiver with SBUS, PPM, and PWM signals output, it is suggested to use for a helicopter, fixed-wing, multicopter, racing drone, glider, car, boat, or robot.

R6DSM: A 10-channel receiver with SBUS or PPM signal output, it is suggested to use for a racing drone or multicopter.



* A single transmitter can pair with up to 30 receivers simultaneously.

Adapts to All Types of Aircraft


Easy-to-understand user software makes quick work of changing aircraft types.

Adaptable models include a helicopter, fixed-wing, glider, multicopter, car, boat, and robot.

The transmitter automatically switches layout depending on the selected mode.

All-in-One Education & Training Transmitter


Simulator Support: Practice indoors with simulator functions during extreme weather like heavy rain or scorching sun, ensuring uninterrupted daily training.

Battle-Proven Anti-Interference Tech: Enables 100 pilots to compete simultaneously in the same field that is free from interference, and dominate the race with confidence!

Wireless Trainer Link: The Instructor can move freely within 600 meters without signal disruption. Unlike restrictive traditional trainer cables, the wireless system liberates instructors from constant standing, running, or jumping, no more "manual labor" during training!

Compatible with TBS Crossfire Modules: Perfectly adapts from beginner to advanced courses, supporting external high-frequency modules for expanded training needs.

Energy-Efficient & Eco-Friendly


The AT9S Pro features a high-efficiency switching power supply, achieving eco-friendly operation with ultra-low power consumption. With an operating current as low as 90mA, which is just half or even one-third of comparable products. Powered by a 3S 1800mAh Li-ion battery, it delivers an impressive 12 hours of continuous use!

Real-time Built-In Telemetry*


Real-time model data allows users to receive crucial information on the display of AT9S Pro.

When receiver R9DS, R12DS is paired with the telemetry module PRM-01, the model voltage will be displayed on the AT9S Pro screen.

*Only the R12DS and R9DS receivers support the telemetry function.


The telemetry module PRM-03 works with R12DS, R12DSE, R9DS and flight controller PIX6, PIXHAWK, CrossFlight-CE, CrossFlight, CrossRace Pro, CrossRace, Mini Pix, TURBO PiX, making AT9S Pro telemetry the model voltage, speed, climb, throttle, longitude, latitude, altitude, GPS, RSSI, flight mode, yaw, roll, pitch, and distance data come true.

All twelve channels can be programmed to any advanced setting*.

An Airbrake function can be set by using pre-programmed mixes.

Multi-mix, such as aileron mix with elevator or flap mix with aileron for fixed-wing or V-shaped tail models.

User-Friendly & Easy to Operate


The AT9S Pro features an intuitive guided menu system that displays on-screen prompts when adjusting settings, effortlessly guiding you through each step. No need to dig through the manual—players can set up and operate with ease right away!

Multiple Battery Input

Anti-polarity Connect Protection


The voltage protection software technology of RadioLink ensures both the transmitter and receiver are protected from a reverse polarity connection.

Industry-standard JST connector makes AT9S Pro adaptable for various battery layouts, 8pcs AA batteries, a 2S-4S LiPo, or a 18650 Lithium battery.

When a TBS Crossfire is connected, a maximum 3S LiPo battery, or a 18650 Lithium battery is supported.

The new power supply circuit provides longer battery life, 12 hours of fun with a 1800mAh 3S LiPo or 18650 Lithium battery.
