Radiomaster GX10

Radiomaster GX10 is a compact gamepad-style RC transmitter, suitable for beginner and advanced pilots who want a smaller radio without compromising on features. Its main advantages are a 2.8" touchscreen IPS display located on the top, an integrated dual-band ELRS module with an LR1121 chip, and X4-V2 hall gimbals with programmable LED backlighting. The transmitter is available in two colour versions – grey (Grey) and smoky transparent (Transparent Charcoal). The variants differ only in colour.

The X4-V2 gimbals use contactless hall sensor detection – control is more precise and there is no wear. The sticks are surrounded by programmable LED rings. Both axis tension, throttle tension, travel range (38-60°), and throttle stick self-centring for conversion between Mode 1 and Mode 2 can be adjusted with screws from the rear without disassembling the radio. The sticks have an M3 thread. Further model control is provided by 4 three-position switches, 4 momentary switches (two of them on the rear), 2 rotary controls, and 6 programmable RGB buttons at the bottom, suitable for switching flight modes, telemetry announcements, or any EdgeTX function. The radio is controlled via the touchscreen, SYS, MDL, TELE, RTN and PAGE buttons, and a scroll wheel.

The display has a 320x240 resolution, and its top placement keeps the transmitter body compact. The radio is powered by an STM32H7 processor, ensuring fast system response, quick model loading, and Lua script execution. Models, sounds, and scripts are stored in the integrated 512MB memory; a microSD card up to 32GB can optionally be used (not included), but inserting it disables the internal memory. The radio uses fully configurable EdgeTX firmware (successor to OpenTX) version 2.12.0 and newer. The built-in motion sensor allows logical switches to be triggered by tilting the radio, camera gimbals to be controlled, or telemetry announcements to be activated. A speaker and microphone for recording custom sounds are also included.

A major advantage of the radio is the integrated ELRS module with a Semtech LR1121 chip, which operates in the 2.4GHz or 868MHz band depending on configuration. The 2.4GHz band is suitable for racing and freestyle thanks to a refresh rate of up to 500Hz and minimal latency, while the lower band is intended for long-range flights. ExpressLRS (ELRS for short) is an open-source project, and transmitting and receiving modules are made by multiple manufacturers. ELRS is currently one of the most advanced RC link systems – it offers a reliable long-range link, high refresh rate, adjustable output power, Wi-Fi updates, and Bluetooth connectivity, allowing wireless connection to a simulator. Module cooling is provided by a quiet fan with an aluminium heatsink. A low-profile rotatable 2.4GHz antenna that sits flush with the radio body is installed from the factory; a dual-band antenna is included for operation on both bands.

On the rear, there is a standard Nano bay for optional expansion with an external transmitter module, a trainer DSC connector, headphone jack, and microSD card slot. The transmitter is powered by two 18650 Li-ion cells (input voltage 6.6-8.4V). The cells are charged with balancing via the USB-C connector, which is also used for firmware updates and simulator connection. The transmitter measures 180x165x83mm and weighs 456g without batteries. The package includes a carrying case, gimbal protector, and display protection film.

Important notice: The antenna must be installed before inserting the batteries and switching on the radio. Operating without an antenna may permanently damage the internal ELRS module. Suitable batteries are unprotected 18650 Li-ion cells with a raised positive terminal („button-top").

Batteries are not included.
