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.

Experience clear visuals on the 3.5-inch IPS touchscreen with 262k color resolution and 600 nits brightness, visible in sunlight. The TX15 Standard features V5.0 hall sensor gimbals in six vibrant colors. It's advanced cooling, a USB-C port for charging, SIM connectivity, firmware updates, and high-speed memory access ensure reliable 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.
