„The GX15 MAX features a 3.5-inch IPS touchscreen display mounted on the top of the fuselage, reproducing 262,000 colors and boasting a brightness of up to 600 nits. The display, located above the controls, allows you to conveniently monitor telemetry data, timers, and other important flight information during flight. This arrangement ensures that the pilot’s hands do not block the screen, so the most important data will always be easily visible.

The high-performance STM32 H7 processor provides significantly increased computing power for the GX15 MAX compared to previous generation models. As a result, the EdgeTX operating system runs smoother, scripts execute faster, and switching between models is almost instantaneous. Integrated Flash memory and support for external TF (microSD) cards provide flexible and secure data storage and management options.

„The GX15 MAX features two Semtech SX1281 transceivers supporting Gemini 2.4 GHz ExpressLRS (ELRS) technology. Designed for modern RC airplanes and helicopters, the controller delivers ultra-low latency and supports ultra-high data refresh rates, including F1000 mode with compatible receivers such as the Nexus-XR. Two integrated antennas, horizontally and vertically positioned behind the display, provide Gemini with redundant communication, polarization diversity, and reliable signal transmission. This solution allows for a compact and seamless design without the need for bulky external antennas.

„The GX15 MAX features precision CNC-machined AG02 joysticks with Hall effect sensors for exceptional control accuracy, smooth operation, and long-term durability. Aluminum buttons, a CNC aluminum scroll wheel, and improved controls provide rigidity and ensure comfortable and precise control. A carbon fiber imitation body complements the premium design, maintaining excellent balance and comfort even during long flights.

The integrated cooling system with a silent fan and aluminum radiators ensures stable operation even during long-term use of the controller or in difficult environmental conditions. The USB-C connector allows you to charge the battery, connect the controller to a flight simulator, update the software and transfer data at high speed.

The intelligent battery management system optimizes power consumption and extends the operating time of the remote control, while the integrated gyroscope provides additional control options. Tilting the remote control can activate logic switches, control functions assigned to the joysticks, or activate audible telemetry messages. This provides more control flexibility without additional equipment.

Interchangeable top switch modules allow pilots to customize the controls to their individual needs, including the ability to replace conventional switches with momentary buttons. The GX15 MAX combines advanced technologies from the GX15 platform, premium materials, precision AG02 CNC control levers and improved controls, providing an exceptional experience for pilots seeking the highest level of control precision and comfort in the GX series.
