A 12-channel Radiolink AT9s Pro radio (2.4 GHz, DSSS + FHSS) with a 2.8″ color display and telemetry.
The radio uses hybrid DSSS and FHSS transmission in the 2.4 GHz band (16 hopping channels), which helps maintain the link in a busy airwave. It has 12 channels, of which 5–12 are user-configurable; telemetry sends the model battery voltage and RSSI signal level. The stated range is up to 4000 m in the air with line of sight.
The transmitter draws under 105 mA, power is under 100 mW (20 dBm); supply is 7.4–18.0 V (2S–4S LiPo or 8 AA batteries). The 2.8″ color display (320×240) simplifies mixer setup, and the compatible receivers are R12DSM, R12DS, R9DS, R6DS and R6DSM.
