RadioMaster continues to lead the charge in open-source radio control innovation. After years of collaboration with our open-source partners and pilot community, we’re proud to introduce the TX15—a game-changing transmitter powered by the blazing-fast STM32 H7 chip. This powerhouse delivers ultra-smooth EdgeTX performance, lightning-fast model switching, and near-instant script execution.

With 4GB of onboard flash and MicroSD card support, you’ll have virtually unlimited space for models, scripts, sounds, and themes—no compromises.

At its core is the Semtech LR1121 transceiver, supporting 2.4GHz and 900MHz ExpressLRS (ELRS) for long-range, low-latency operation. Whether you're flying every day or pushing limits in tough RF environments, the TX15 is built to perform. A smart battery balancing circuit helps extend your sessions, and the compact, foldable antenna keeps your gear bag tidy while maintaining excellent signal quality.

The built-in gyro sensor unlocks TiltX/TiltY functions—let you pan/tilt cameras, trigger switches, or call out telemetry simply by moving your radio. Yes, it's that smart.

Enjoy crystal-clear visuals on the 3.5" IPS touchscreen, boasting 262K colors and 600 nits of brightness—easily viewable even in direct sunlight. The TX15 Standard comes with V5.0 hall sensor gimbals in six bold color options. With improved cooling, USB-C charging, SIM connectivity, and high-speed firmware updates, you’re always connected and in control.

Need a bit more customization? Extra switches are included so you can replace the top shoulder buttons with either momentary or two-position latching switches—ideal if you prefer traditional toggles.

Looking for something even more premium? Don’t miss the TX15 MAX.
