TX15 Max ELRS M2 Radio Controller Professional FPV RC Transmitter Long Range, Low Latency Remote For Drones & Aircraft (RED)

RadioMaster TX15 MAX: The Future Is Here, One Step Ahead

RadioMaster continues to redefine the open-source remote control landscape. After years of collaboration with open-source partners and users, we proudly introduce the TX15 MAX — a next-generation radio controller engineered for ultimate precision, performance, and style.

Powered by the high-performance STM32 H7 chip, the TX15 MAX delivers ultra-smooth EdgeTX control, instant model switching, and lightning-fast script execution. With 4GB of flash storage and MicroSD card expansion, it offers virtually unlimited space for models, scripts, sounds, and themes.

Equipped with the LR1121 Semtech transceiver, the TX15 MAX supports both 2.4GHz and 900MHz ExpressLRS (ELRS), providing long-range and low-latency performance even in challenging RF environments. A smart balance battery circuit extends flight time, while the foldable antenna design enhances portability and signal reliability.

The built-in gyro with TiltX/TiltY functions unlocks advanced control possibilities — enabling you to trigger switches, pan/tilt cameras, or activate telemetry callouts simply by tilting your radio.

Enjoy sharp, vibrant visuals on the 3.5-inch IPS touchscreen featuring 262k color resolution and 600 nits brightness, ensuring clear visibility even under sunlight. The TX15 MAX stands out with AG02 CNC aluminum gimbals (available in red, black, or gold), upgraded aluminum buttons, a scroll wheel, and a carbon-fiber-look case for a premium feel.

Integrated RGB LED gimbal rings allow LUA-controlled lighting customization, while the efficient cooling system, USB-C port, SIM connectivity, and firmware update support ensure top-tier reliability and performance. Interchangeable shoulder switches give you full control customization, letting you choose between momentary or latching styles.
