RadioMaster continues to redefine the open-source remote control landscape. After years of collaboration with our open-source partners and users, we are proud to introduce the TX15. Driven by the high-performance STM32 H7 chip, it’s the powerhouse behind 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 features a LR1121 Semtech transceiver, supporting both 2.4GHz or 900MHz ExpressLRS (ELRS) for long-range, low-latency performance. Whether you're flying daily or operating in challenging RF environments, the TX15 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. We’ve included additional switches so you can swap out the shoulder buttons with either a momentary or two-position latching switch—perfect if you prefer a traditional switch over a button
