Radiomaster GX10 Max

Radiomaster GX10 Max is a compact gamepad-style RC transmitter, suitable for pilots who want a smaller radio without compromising on features. Its main advantages are all-aluminium AG01 Mini V2 Hall gimbals, a 2.8" IPS touchscreen located at the top of the radio, and an integrated ELRS module with an LR1121 chip operating at 2.4GHz or in the 868MHz band. The Max is the higher-end version of the GX10 series.

The AG01 Mini V2 gimbals are CNC-machined from aluminium and mounted on four precision bearings. They detect position contactlessly using Hall sensors, ensuring precise control without sensor wear. Throw range (38–60°), spring tension, and throttle centering can be adjusted externally with an Allen key without disassembling the transmitter. This also makes it easy to switch the gimbals between Mode 1 and Mode 2. The sticks are surrounded by RGB LED rings with programmable colours and feature an M3 thread. Additional model controls include 4 three-position switches, momentary buttons (two of them on the rear), and 2 rotary wheels on the rear. At the bottom, there are also 6 programmable RGB buttons, suitable for flight modes, telemetry announcements, or any EdgeTX functions. The radio is configured using the SYS, MDL, TELE, RTN and PAGE buttons and a machined aluminium scroll wheel. The rear grips have a non-slip leather covering and can be removed to access the battery compartment.

The 2.8" display has a resolution of 320x240 and, according to the manufacturer, remains clearly visible even in direct sunlight. The radio is powered by an STM32H750 processor, allowing EdgeTX to run smoothly and load models and LUA scripts quickly. It features 512MB of internal memory and a microSD card slot (up to 32GB, FAT32). Inserting a card disables the internal memory. The radio uses fully configurable EdgeTX firmware (the successor to OpenTX), version 2.12.0 and newer, and is updated via USB-C (UF2). The built-in motion sensor allows the radio to control, for example, a camera gimbal by tilting or trigger logical switches. The microphone is used to record custom voice announcements. A speaker and 3.5mm headphone jack are also included.

A major advantage of the radio is its integrated ELRS module with a Semtech LR1121 chip and ExpressLRS 3.6.3 firmware. It supports up to 16 channels (depending on the receiver) and refresh rates of up to 500Hz at 2.4GHz. The module always operates in one band according to its configuration: 2.4GHz for racing and freestyle with minimal latency, or 868/915MHz for long-range. ExpressLRS (ELRS for short) is an open-source project, with transmit and receive modules produced by multiple manufacturers. ELRS is currently one of the most advanced RC control links. It offers a reliable long-range link, high refresh rates, and adjustable output power. The module is actively cooled by a quiet fan with an aluminium heatsink. It comes fitted with a low-profile rotating 2.4GHz antenna that does not protrude from the radio body. A dual-band antenna is included for operation in the 868/915MHz band. The antennas connect via an MMCX connector, and the included tool is used for replacement.

On the rear, there is a Nano bay for optional expansion with an external transmitter module and a DSC trainer port. The transmitter is powered by two 18650 Li-ion cells or a 2S LiPo battery (input voltage 6.6–8.4V). The battery is charged via the USB-C connector with integrated balancing, which protects the cells from overcharging and extends their lifespan. The same connector is also used for data transfer and simulator connection. Unprotected 18650 cells with a raised positive terminal (“button top”) and a charging voltage of 4.2V per cell are suitable.

Compared to the standard GX10 version, the Max features all-aluminium AG01 Mini V2 gimbals instead of X4-V2, a machined aluminium menu wheel, and an exclusive carbon-look case finish. It is 29g heavier, weighing 485g without batteries. The GX10 Max is available in three colour options: Gold, Red, and Transparent Charcoal. The package includes a carrying case, gimbal protector, and display protective film.

Important notice: Always switch on the transmitter with the antenna installed. Operating without an antenna will permanently damage the ELRS module, and such damage is not covered by warranty.

Batteries are not included.
