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.
