RadioMaster continues to raise the bar in open-source radio control. After years of collaboration with our open-source partners and user community, we're proud to introduce the TX15 MAX—our fastest, most feature-packed radio yet. Powered by the high-performance STM32 H7 chip, the TX15 MAX delivers buttery-smooth EdgeTX control, instant model switching, and ultra-fast script execution.

With 4GB of internal flash and MicroSD expansion, you'll have more than enough room for all your models, themes, sounds, and scripts—whether you're tuning for freestyle, racing, or long-range missions.

At the heart of the TX15 MAX is the Semtech LR1121 transceiver, offering dual-band 2.4GHz and 900MHz ExpressLRS (ELRS) support for exceptional range and ultra-low latency. A smart battery balancing circuit extends your flight time, while the sleek, foldable antenna keeps the radio portable without compromising signal strength.

Advanced features like the integrated gyro sensor with TiltX/TiltY let you pan cameras, toggle switches, or trigger telemetry alerts—all with a simple tilt of the radio. No hands? No problem.

The 3.5-inch IPS touchscreen delivers brilliant, daylight-visible visuals with 262K colors and 600 nits brightness. But what really sets the MAX apart is its hardware: AG02 CNC aluminum gimbals in your choice of anodized red, black, or gold, premium aluminum buttons, a carbon-fiber-look shell, and a tactile scroll wheel for easy navigation. Built-in RGB LEDs around the gimbals are fully customizable with LUA scripts—perfect for matching your style or flight mode at a glance.

You’ll also get USB-C fast charging, SIM card connectivity, high-speed firmware updates, active cooling, and top-tier memory access. Plus, we’ve included extra switch modules so you can swap the top shoulder buttons for momentary or latching switches—ideal if you prefer toggles over buttons.
