RadioMaster GX12 Dual-Band Gemini-X Radio Controller
Rs. 19,499.00
The RadioMaster GX12 is a full-size EdgeTX radio built around two 1W ExpressLRS Gemini Xrossband transmitters, so it can run 2.4GHz and Sub-GHz 900MHz at the same time for a redundant, long-range link. It pairs GX01 fully CNC aluminium 1000Hz Hall-effect gimbals with folding dual-band antennas, a high-contrast OLED screen and 512MB of internal storage – no SD card needed.

Compatibility
Binds to: any ExpressLRS receiver - 2.4GHz (every ELRS whoop, AIO and nano receiver), 900MHz, and dual-band Gemini receivers (XR4, DBR4, GEPRC Gemini).
Does not bind to: DJI drones, FrSky or FlySky - add a Nano-bay module (e.g. TBS Crossfire Nano) for Crossfire.
In India: the licence-free sub-GHz band is 865-867MHz. Flash the radio's ELRS firmware (and your receivers) to the IN866 domain before flying on 900MHz. 2.4GHz works as shipped.
Power: 1W output at full power drains batteries quickly - most FPV flying uses 100-250mW.
