As FPV drones continue to grow in popularity among DIY makers and hobbyists, the need for reliable, compact, and versatile radio transmitters is more important than ever. Whether you’re into racing, freestyle, or cinematic FPV, the radio link is what connects you to your drone in real time.
In this article, we take an in-depth look at the Radiomaster GX12, a dual-band, EdgeTX-powered controller built for modern FPV pilots. We’ll evaluate its features, performance, and how it fits into real-world drone builds — especially for those who value portability without sacrificing power.

What Is the Radiomaster GX12?
The Radiomaster GX12 is a compact, dual-band radio controller designed for FPV drone pilots who want high-performance control in a smaller, more portable form factor. It supports ExpressLRS (ELRS) and CRSF, two of the most popular protocols for low-latency, long-range FPV flying.
Unlike traditional full-size radios like the TX16S, the Radiomaster GX12 is aimed at pilots who fly on the go, travel with their gear, or prefer a gamepad-style transmitter that doesn’t compromise on performance.

- EdgeTX operating system with customizable menus
- Hall sensor gimbals with smooth, precise movement
- Touchscreen interface for easy navigation
- Built-in Bluetooth and WiFi for OTA updates
- USB-C charging and simulator support

First Impressions & Build Quality
Out of the box, the Radiomaster GX12 feels premium. The plastic shell is solid and well-finished, with rubberized grips that offer a comfortable hold. The gimbals are some of the best in its class, smooth and tension-adjustable — perfect for those who care about stick precision.
The touchscreen is responsive and intuitive, and pilots familiar with EdgeTX will feel right at home. Menu navigation is fast, and configuration options are extensive, making it easy to bind new models or tweak rates in the field.

Radiomaster GX12 in Real-World Flying Scenarios
To put the Radiomaster GX12 to the test, we paired it with a custom 5-inch freestyle drone powered by MEPS NEON 2306 motors and a 60A ESC. Using the built-in ELRS 2.4GHz module, we ran a series of tests to measure signal strength, latency, and overall flying experience.
Flight Performance Results:
- Signal Strength: Rock-solid connection up to 2 km line-of-sight using stock antennas
- Latency: Almost unnoticeable — ideal for acro flying and fast response
- Link Recovery: Fast reconnection after signal drops or low RSSI events
- Interference Handling: No noticeable interference with DJI digital video system on board
The Radiomaster GX12 held up impressively well even in urban environments with moderate signal congestion, making it a reliable choice for freestyle and long-range pilots alike.
