AT-9S RC Radio & Receiver Mode 2

Dhs. 600.00

The Radiolink AT9S 2.4G transmitter operates on the DSSS and FHSS spectrum synchronously. With 16 pseudo random channels and QPSK modulation, the AT9S operates interference-free even on urban land. With a range exceeding 900 meters on land and 1500 meters in the air.

Supports SBUS, PPM and PWM , with the possibility of working at the same time. The AT9S comes standard with a receiver R9DS with SBUS and PWM output simultaneously. Compatible also with the diversity receiver R10DS also SBUS and PWM, with small receiver R6DS that supports SBUS, PPM and PWM simultaneously with the micro receiver R6DSM that supports SBUS and PPM.

The consumption of this transmitter is really low, with only 90mA, with a battery LiPo 3S of 1800mAh, can work for more than 12 hours. The AT9S PCB design is designed to avoid interference from SMPS.

The battery connector is a universal JST connector with anti-polarity system, you will never have to worry about connecting the battery correctly to avoid a crossing. It works with 8 AA batteries, with 2S-4S LiPo or other types of batteries.

With an accuracy of 4096, the maximum jitter of the PWM signal is 1.84us and the normal jitter is 0.5us. This provides a vibration-free control of the tail servos.

Thinking about the FPV, the AT9S carries a complete repertoire of sound warnings and vibrations. Vibration due to low reception, low transmitter voltage, low receiver voltage and extended low motor voltage.

All your controls from the switches, to the menu selection wheel, are humanized, easy to access and highly intuitive. Two wheel switches, two slider switches, three 3-way switches, 4 two-way switches and one reset trainer switch.

With integrated USB connector, updates are welcome. And perfect for backing up all of our parameters.

MIX programmable, either with basic menu, advanced or graphic to help you see throttle variations or servos curves. Channels 5-10 are customizable.
