RadioLink AT9S Transmitter w/ R9DS Receiver

Functions

DSSS & FHSS Spread Spectrum: DSSS & FHSS work synchronously; 16-channel pseudo-random frequency hopping and QPSK modulation provide excellent anti-interference performance. Even normal operation in the city center is possible.

Actual measurement: 900 meters on the ground and 1,500 meters in the air.

Real-time data telemetry: Supports signal strength, receiver voltage monitoring, and the advanced motor voltage telemetry module PRM-01 and OSD information telemetry module PRM-02. When used with the APM or PIX flight controller, PRM-02 can transmit GPS, SPEED, voltage, etc. back to the AT9S display.

The most complete range of types and functions: Suitable for all aircraft, including helicopters with 8 swashplate modes, fixed-wing aircraft with 2 tails and 3 wings, gliders with 4 wings and 2 tails, as well as multicopters, RC cars, and boats.

Top configuration: MCU: STM32F103VET6 (32-bit RISC core operating at a frequency of 72 MHz, 512 KB flash memory, two 12-bit ADCs). Chip: TI CC2533, the most advanced chip ever used in an RC transmitter.
Multilingual: English, Spanish, German, Italian, French, Turkish, Russian, Korean, and Chinese menus.

Supports SBUS, PPM, and PWM: SBUS, PPM, and PWM signals can work simultaneously. The AT9S is supplied with an R9DS receiver, featuring simultaneous SBUS and PWM signal output. It is also compatible with the diversity antenna receiver R10DS, featuring simultaneous SBUS and PWM signal output. The super-mini R6DS receiver features simultaneous SBUS, PPM, and PWM signal output!

Receiver: R9DS, with simultaneous SBUS, PPM, and PWM signals, easy to connect.

Green and low power consumption: The switched-mode power supply (SMPS) keeps the operating current at 90 mA when using a 3S LiPo battery—half or even one-third of the consumption of comparable products. With a capacity of 1,800 mAh, a 3S LiPo battery can operate for more than 12 hours. The AT9S PCB design prevents interference caused by the SMPS.

Intelligent reverse-polarity connection protection: You do not need to worry about damaging your transmitter, even if you accidentally connect the polarity incorrectly.

A universal JST battery connector and a wide input-voltage range ensure support for multiple batteries, including 8 AA batteries, 2S–4S LiPo batteries, and other types of batteries.

4096 precision: The 4096-step precision provides a maximum PWM signal jitter of 1.84 µs and normal jitter of 0.5 µs—one quarter that of the AT9 and one sixth that of competing products—and ensures servo anti-vibration performance.

Multiple alarm notifications: Low RSSI vibration alarm setting, low transmitter voltage, low receiver voltage, and low advanced motor voltage alarms. Vibration, DD sounds, and spoken alarms prevent unawareness in noisy environments and ensure safe flight.

Humanized design: Simple settings: The navigation menu guides you to the next step, simplifying operation and configuration. Easy to use, even without reading the manual.

USB upgrade: Upgrading via a USB cable ensures that the AT9S always retains the most advanced system and program. The AT9S USB backup function helps you easily save and copy parameter settings.

Programmable MIX control: Basic menu, advanced menu, and graph display for various throttle and servo curves. Channels 5–10 can be adjusted. Advanced settings according to your preferences.

Humanized switch positioning: Two rotary knobs, two sliders, three three-position switches, four two-position switches, and a reset trainer switch. Supports multiple antenna control modes and PTZ control. The VR switches are galvanized and UV-resistant.
