Radiolink AT9S 2.4G 10CH DSSS FHSS Transmitter with R9DS 9CH Receiver Radio Controller System S-BUS PPM PWM for RC Helicopter Fixed Wing Glider Multicopter Car Boat



DSSS and FHSS spread-spectrum technology working synchronously, 16 channels pseudo random frequency hopping, QPSK modulation ensure excellent anti-interference performance, free from 1.2G&5.8G image interference and 433MHz data transmission interference. Even can controlled normally in city center.




MCU: STM32F103VET6( 32-bit RISC core operating at a 72 MHz frequency, 512 Kbytes of Flash memory, two 12-bitADCs).

Chip: TI CC253, the most advanced chip ever in a RC transmitter.

Actual measurement: ground 900 meters and air 1500 meters.



Suit for all airplanes including helicopter 8 swash plate modes, fixed wing 2 airfoils 3 rears, gliders 4 airfoils 2 rears and multicopter, RC cars and boats.



Support signal strength, receiver voltage monitored, and extended engine voltage telemetry module PRM-01 and OSD info telemetry module PRM-02. PRM-02 can feedback GPS, SPEED, voltage etc. on AT9S display when work with flight controller APM or PIX.



English, Spanish, German, Italian, French, Turkish, Russian, Korean and Chinese menu.



S-BUS, PPM and PWM signal possible working at the same time.

AT9S sells with receiver R9DS, SBUS and PWM signal output simultaneous.

Also, compatible with diversity antenna receiver R10DS, support SBUS and PWM signal output simultaneous.

Supper mini receiver R6DS, support SBUS, PPM and PWM signal output




R6DS, with the super mini size 25*16mm and the 3.9 grams weight, support SBUS, PPM and PWM signal working at the same time, easy to connect and never burden to your drones, is the best choice for drone!


Green and low consumption

90mA operating current: Switching Mode Power Supply ensure the operating current keep to 90mA when using 3S LiPo battery, a half or even one third consumption of the similar products. Brand new hardware design of AT9S solve the interference of SMPS. With a 1800mAh, 3S LiPo battery can working more than 12 hours.


Anti-polarity connect protection intelligent

Do not worry about that damage your transmitter even connect anti-polarity.

JST battery connector: ensure multiple battery support, 8pcs AA batteries or 2S-4S LiPo battery and other kinds of batteries.



4096 section precision, the max PWM signal jitter is 1.84us, and the regular jitter is 0.5us ensure servos anti-shake rudder.



Low RSSI vibration alarm setting, low transmitter voltage, receiver voltage and extended engine voltage alarm.

Vibration, DD sounds and words alarming avoid any ignorance in a noisy condition, ensure a safe flight.



Navigation menu offering next step, simplified the operating and setting.



Upgrade by a USB cable keeps always the most advanced system and program.

The USB data backup copy function of AT9S help you save and copy parameter settings easily.



Basic menu, advanced menu, graph view for varieties of throttle and servo curve, 5-10 channels are customized.

Simplified the multicopter attitude menu setting, even beginners can set easily!



Two knob switches, two slicer switches, three three-gear switches, four two-gear switches, a reset trainer switch.

Support multiple aerial control mode and PTZ control.

VR switches are galvanized and sub UV design.
