RadioMaster TX15 Max Radio Transmitter - ELRS 2.4GHz

The RadioMaster TX15 Max Radio Transmitter - ELRS 2.4GHz continues to redefine the open-source remote control landscape after years of collaboration with our open-source partners and users. 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 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.
