Radiolink AT9S is a 2.4GHz 9CH transmitter applicable for all 120-degree and 90-degree swash-plate helicopter, all fix wings, gliders, and multi-rotors. It has fast response, 3ms only, even its 9 channels act synchronously. Its menu supports many languages and different levels. DSSS and FHSS dual spread spectrum technology improve the anti-interference performance and transmission distance. The R9DS receiver integrates signal strength and voltage telemetry sensor.

Main Features:
Fast response, 3ms only, which is much less than the average 20ms even 9 channels act synchronously
● Long control distance: more than 900 meters on ground, 1500 meters in air
● English, Chinese, Espanol, Deutsch, French, Italiano, Turkish, Russian and Korean menu can be switched
●DSSS and FHSS spread-spectrum technology working synchronously, QPSK modulationsupportexcellent anti-interference performance
●Programmable mix control. Basic menu, advanced menu, graphic view for verities of throttle and servo curve
