Product Description
The RadioMaster GX12 is RadioMaster's flagship compact radio controller, featuring the revolutionary Gemini Xrossband dual-band ExpressLRS system that simultaneously transmits on both 2.4GHz and 900MHz frequencies for unmatched link reliability and range. Powered by dual 1W Gemini Xrossband transmitters and featuring CNC-machined GX01 aluminum gimbals with 3D Hall sensors running at 1000Hz, the GX12 represents the pinnacle of compact radio design for serious FPV pilots and UAV professionals who demand the best in RF performance and build quality.
The GX12 features a 128×64 OLED display for sharp, clear readability in bright sunlight, 512MB of internal flash storage for model profiles and audio, and programmable 6-position switches with RGB indicators for flexible model configuration. The 1000Hz digital gimbal system syncs directly with EdgeTX for the lowest possible input latency, while PCB nano coating provides protection against moisture and dust in field conditions. The advanced cooling system manages the thermal demands of dual 1W transmitters for sustained high-power operation during long FPV sessions.
