RadioMaster TX15 ELRS Radio Controller Mode 2 Transmitter

RadioMaster continues to push the boundaries of open-source radio control. Built from years of collaboration with the EdgeTX and ExpressLRS communities, the TX15 delivers uncompromising performance, advanced features, and a modern design—engineered for pilots who demand speed, reliability, and flexibility.

At the heart of the TX15 is a high-performance STM32 H7 processor, making it the fastest RadioMaster transmitter to date. This powerhouse enables ultra-smooth EdgeTX operation, instant model switching, and lightning-fast script execution. With 4GB of onboard flash memory plus MicroSD expansion, you’ll have virtually unlimited space for models, scripts, sounds, and themes.

The TX15 features an integrated Semtech LR1121 transceiver, supporting both 2.4 GHz and Sub-G 900 MHz ExpressLRS (ELRS) for long-range, low-latency control. Whether you’re flying daily or operating in congested RF environments, the TX15 delivers consistent, reliable performance. A smart balance battery circuit maximizes efficiency and runtime, while the compact foldable antenna enhances portability without sacrificing signal strength.

A built-in gyro with TiltX and TiltY functions unlocks intuitive control options—allowing you to trigger switches, control pan/tilt cameras, or activate telemetry callouts simply by tilting the radio.

Visuals are handled by a stunning 3.5-inch IPS touchscreen with 262K colors and 600 nits brightness, remaining clear and readable even in direct sunlight. The TX15 Standard is equipped with V5.0 Hall-sensor gimbals, available in six vibrant colors, delivering precise, smooth control.

Designed for durability and long sessions, the TX15 includes an efficient cooling system with low-noise, high-output fans and an aluminum heat sink. A USB-C port supports charging, SIM connectivity, firmware updates, and high-speed data access. For added customization, extra switches are included so you can replace the shoulder buttons with momentary or two-position latching switches, catering to pilots who prefer a traditional switch layout. The TX15 is a powerful, customizable, and future-ready radio—built to evolve with the open-source ecosystem.
