RadioMaster GX15 MAX — Premium ExpressLRS Radio Controller
The ultimate GX-series transmitter for demanding pilots
RadioMaster expands its acclaimed GX series with the GX15 MAX, a premium radio controller designed for pilots who fly RC airplanes, gliders, helicopters, and other traditional aircraft.
Combining high-performance electronics, precision CNC-machined controls, premium materials, and advanced dual-antenna ExpressLRS technology, the GX15 MAX is built for pilots who demand exceptional control, responsiveness, and reliability.
For pilots looking for the same core GX15 performance in a more accessible configuration, the standard GX15 is also available.
At Aerobertics, we see the GX15 MAX as a transmitter designed not only to perform at the highest level, but also to make every flight feel more precise, intuitive, and enjoyable.
Key Features
High-Performance STM32 H7 ProcessorThe powerful STM32 H7 processor delivers fast system performance, smooth EdgeTX operation, rapid script execution, and near-instant model switching.
3.5-inch IPS Touchscreen DisplayThe 480 × 320 IPS touchscreen features 262K colors and up to 600 nits of brightness, providing excellent visibility even in bright outdoor conditions. Positioned above the controls, the display keeps telemetry, timers, and flight information clearly visible without being obstructed by your hands.
Premium AG02 CNC Hall-Effect GimbalsPrecision-machined AG02 CNC aluminum gimbals provide an exceptionally smooth and precise control feel, combined with excellent durability and long-term consistency.
Dual 2.4GHz ExpressLRS GeminiTwo Semtech SX1281 250mW transceivers deliver dual-radio Gemini performance, providing redundancy, low latency, and support for ultra-fast ExpressLRS update rates, including F1000 operation with compatible receivers such as the Nexus-XR.
Dual Integrated AntennasHorizontal and vertical internal antennas provide polarization diversity and complement the Gemini architecture, helping maintain reliable signal performance while keeping the transmitter exterior clean and free from bulky external antennas.
Intelligent Battery ManagementAn advanced power-management system optimizes energy consumption to help extend operating time while maintaining stable performance.
Efficient Cooling SystemA low-noise cooling fan combined with aluminum heat sinks helps maintain stable operating temperatures during extended flying sessions and demanding conditions.
Premium CNC Aluminum ControlsAluminum buttons and a precision CNC-machined scroll wheel provide a solid, refined interface and premium tactile feedback.
Built-in GyroscopeThe integrated motion sensor enables tilt-based control functions, including logical switches, gimbal inputs, and telemetry functions—adding new possibilities without requiring additional hardware.
Built-in MicrophoneThe microphone is integrated into the transmitter and reserved for future feature expansion.
Dual Storage SystemThe GX15 MAX features 512MB of built-in flash storage and external microSD support for flexible model and data management.Note: inserting a microSD card disables the onboard flash storage.
Interchangeable Shoulder SwitchesReplaceable shoulder panels allow pilots to configure the transmitter to their preferred control layout, including the option to install momentary buttons.
Premium Carbon-Look CaseThe carbon-look housing gives the GX15 MAX a distinctive premium appearance while maintaining a comfortable balance for extended flying sessions.
Five Color OptionsAvailable in Black, Transparent Charcoal, Red, Gold, and Blue.
Designed Around the Pilot
The GX15 MAX features a top-mounted 3.5-inch IPS touchscreen, placing important flight information directly within your field of view. Telemetry, timers, model information, and other essential data remain easy to monitor throughout the flight without your hands blocking the screen.
At the heart of the transmitter is a powerful STM32 H7 processor, bringing a significant performance boost to the EdgeTX experience. Faster processing means smoother operation, quicker script execution, and virtually instantaneous model switching.
The GX15 MAX also combines 512MB of onboard flash storage with external microSD support, giving pilots flexible options for managing models, scripts, sounds, and other data.
Dual-Radio Gemini ExpressLRS Performance
The GX15 MAX comes equipped with dual Semtech SX1281 transceivers, delivering advanced 2.4GHz ExpressLRS Gemini performance.
This dual-radio architecture is designed for pilots who value low latency, high update rates, redundancy, and dependable signal performance. With compatible receivers, the GX15 MAX supports ultra-fast ExpressLRS update rates, including F1000.
The two integrated antennas are positioned behind the display in horizontal and vertical orientations. Together with Gemini technology, this configuration provides radio redundancy and polarization diversity, while keeping the transmitter sleek and antenna-free on the outside.
ExpressLRS comes installed as standard, so the GX15 MAX is ready to take advantage of one of the most advanced open-source radio-control link technologies available today.
Precision You Can Feel
The GX15 MAX is equipped with RadioMaster AG02 CNC Hall-effect gimbals, combining precision-machined aluminum construction with smooth, accurate Hall-effect sensing.
The result is a highly refined control experience with excellent stick precision, smooth movement, and long-term durability.
The premium feel continues throughout the transmitter with CNC aluminum buttons, a CNC aluminum scroll wheel, and refined control elements.
For pilots who spend long hours at the sticks, the GX15 MAX is designed to feel as good in the hands as it performs in the air.
Smart Features for Modern RC Pilots
The integrated gyroscope opens the door to additional control possibilities. Tilt-based functions can be assigned to logical switches, gimbal movements, or telemetry voice prompts, providing an additional layer of flexibility without adding external hardware.
The interchangeable shoulder panels allow pilots to tailor the transmitter to their preferred setup. Depending on your flying style, switches can be configured or replaced with momentary buttons for a more personalized control layout.
The USB-C connection supports charging, simulator use, firmware updates, and high-speed data transfer, making the GX15 MAX a versatile transmitter both at the flying field and at home.
The GX15 MAX comes pre-installed with ExpressLRS 2.4GHz, giving pilots access to a modern, high-performance radio link designed for low latency, excellent range, and highly configurable operation.
ExpressLRS uses advanced LoRa-based technology and has become a leading choice among RC pilots who prioritize reliable control, efficiency, and fast response.
Combined with RadioMaster's dual-radio Gemini architecture, the GX15 MAX offers a powerful platform for today's demanding RC aircraft and helicopter applications.
The Aerobertics Choice
The GX15 MAX is more than an upgrade in specifications—it is an upgrade in the way you fly.
From the precision of the AG02 CNC Hall-effect gimbals to the responsiveness of the STM32 H7 processor and the redundancy of dual ExpressLRS Gemini, every element has been designed around one objective: giving pilots confident, precise control when it matters most.
At Aerobertics, we appreciate equipment that delivers both outstanding performance and a premium flying experience. The RadioMaster GX15 MAX brings those two qualities together in one exceptionally capable transmitter.
