The GX15 features a top-mounted 3.5-inch IPS touchscreen with 262K colors and up to 600 nits brightness. Positioned above the controls, the display keeps telemetry, timers, and flight information easily visible throughout flight, allowing pilots to monitor critical data without their hands obstructing the screen.
Powered by a high-performance STM32 H7 processor, the GX15 delivers a significant increase in computing performance over previous generations. The result is a smoother EdgeTX experience, faster script execution, and near-instant model switching. With onboard flash memory and support for external TF cards, the GX15 offers a dual-storage system for secure and flexible data management.
At its core, the GX15 features dual Semtech SX1281 transceivers, each delivering 250mW output power, supporting Gemini 2.4GHz ExpressLRS (ELRS). Designed for modern aircraft and helicopter systems, the GX15 delivers low-latency control and supports ultra-fast update rates, including F1000 operation with compatible receivers such as the Nexus-XR. Working together with dual integrated antennas positioned behind the display in both horizontal and vertical orientations, the system provides Gemini redundancy, polarization diversity, and reliable signal performance while maintaining a clean form factor free from bulky external antennas.
The standard version includes V6 Hall-effect gimbals and is available in five color options. A built-in cooling system ensures stable performance during extended use, and the USB-C interface supports charging, simulator connectivity, firmware updates, and high-speed data transfer.
A smart battery management circuit improves efficiency and extends operating time, while the built-in gyroscope enables additional control inputs. Tilt-based functions can be used to trigger logical switches, control gimbal movement, or activate telemetry voice prompts—adding flexibility without additional hardware.
Interchangeable shoulder switch modules allow pilots to configure controls to their preference, including the option to replace switches with momentary buttons.
