RadioMaster TX15 MAX – The Ultimate Radio Controller for FPV and Drones

RadioMaster continues to redefine the open-source remote control landscape. After years of collaboration with open-source partners and users, we proudly introduce the TX15 MAX. Powered by the high-performance STM32 H7 Chip, it’s our fastest radio ever, enabling ultra-smooth EdgeTX control, instant model switching, and lightning-quick script execution. With 4GB of flash storage and MicroSD card expansion, you’ll have virtually unlimited space for models, scripts, sounds, and themes.

The TX15 MAX features an LR1121 Semtech Transceiver, supporting both 2.4GHz and 868MHz ExpressLRS (ELRS) for long-range, low-latency performance. Whether you’re flying daily or in challenging RF environments, the TX15 MAX is built to perform. A smart balance battery circuit maximizes flight time, while the compact, foldable antenna design improves portability and ensures strong signal quality. The built-in gyro with TiltX/TiltY functions unlocks advanced control options, allowing you to trigger switches, pan/tilt cameras, or activate telemetry callouts with a simple tilt of your radio.

Enjoy sharp visuals on the 3.5-inch IPS touchscreen with 262k color resolution and 600 nits brightness, even in sunlight. The TX15 MAX boasts AG02 CNC aluminum gimbals in anodized red, black, or gold, upgraded aluminum buttons, a scroll wheel, and a carbon-fiber-look case for a premium feel. Integrated RGB LED lights around the gimbals allow customizable LUA-controlled lighting. It includes advanced cooling, a USB-C charging port, SIM connectivity, firmware updates, and fast memory access for top-tier performance. Additional switches allow you to swap out shoulder buttons with either a momentary or two-position latching switch—perfect for those who prefer a traditional switch.

TX15 MAX: The Future Is Here, One Step Ahead.
