📡 Product Overview
The RadioMaster GX12 is a compact, rugged EdgeTX radio controller designed around the Gemini Xrossband ExpressLRS ecosystem. It combines GX01 CNC aluminum 3D digital Hall-effect gimbals with high-resolution 1000Hz sampling, foldable gimbal sticks and a bright 128 × 64 monochrome OLED display.
Two integrated RF transmitters can deliver up to 1W per link using 2.4GHz and Sub-G 900MHz. Folding dual-band antennas and compatible ExpressLRS receivers provide flexible RF operation. The GX12 is suited to FPV aircraft, robotics, remote systems and other compatible RC platforms.
An adjustable control layout includes removable switch panels, programmable six-position switches with RGB indicators and optional SMA antenna modification points. Internal 512MB flash, USB-C connectivity and a cooled RF design help make the GX12 a functional field radio.

📡 Gemini Xrossband and 1000Hz CNC Gimbals
GX12 pairs dual-band Gemini-X with precise CNC-machined GX01 gimbals. The high sampling rate and folding sticks make it well suited to compact transportation and accurate flight control. The twin band link may require compatible receivers and regulatory settings; do not assume all receivers support dual-band operation.
✅ Why Choose the RadioMaster GX12 Dual-Band Gemini-X Radio Controller?
The GX12 is an excellent option when portable form factor, strong ExpressLRS RF capabilities and precision metal gimbals matter more than a large color touchscreen. Integrated folding antennas and 512MB of onboard flash keep the system compact.
