📡 Product Overview
The RadioMaster GX15 Radio Controller is a full-size ExpressLRS transmitter for fixed-wing airplanes, gliders, helicopters and compatible multirotor aircraft. Its combination of an STM32 H7 processor, vibrant 3.5-inch IPS touchscreen and accurate V6 Hall-effect gimbals is designed to support smooth, precise control and fast EdgeTX operation.
Unlike the GX15 MAX with CNC AG02 gimbals and premium aluminum controls, the standard GX15 uses V6 Hall-effect gimbals while preserving the high-performance processor, full-color display and dual-chip Gemini ExpressLRS RF architecture.
Its 2.4GHz ExpressLRS system uses two Semtech SX1281 RF transceivers, each capable of up to 250mW output. Two integrated antennas positioned behind the display provide horizontal and vertical polarization diversity without external protruding antennas. Compatible receivers can support high-speed link rates including F1000.
The top-mounted touchscreen keeps telemetry and flight details in view, and replaceable shoulder switches permit customized control layouts. A quiet cooling system, onboard flash memory, external microSD support and USB-C connectivity expand the radio's capabilities.
