RadioMaster TX15 Max Radio Controller (ELRS / M2)
RadioMaster continues to redefine the open-source remote control landscape. After years of collaboration with open-source partners and users, we are proud to introduce the RadioMaster TX15 Max Radio Controller.
Powered by the high-performance STM32 H7 chip, this is our fastest radio to date. It supports ultra-smooth EdgeTX control, instant model switching, and lightning-quick script execution. Besides, it comes with 4GB flash storage and MicroSD expansion for nearly unlimited space to store models, scripts, sounds and themes.
Dual-band ExpressLRS RF System
The TX15 MAX is equipped with a Semtech LR1121 transceiver. It supports 2.4GHz and 900MHz ExpressLRS (ELRS) to achieve outstanding low-latency performance. Moreover, it stays stable both for daily use and tough RF environments.
To further boost practicality, it adopts a smart balance battery circuit to extend runtime. Meanwhile, its compact foldable antenna keeps strong signal while improving portability. The built-in gyro supports TiltX/TiltY functions; as a result, you can trigger switches or adjust telemetry simply by tilting the transmitter.
Premium Display & Hardware Build
For clear outdoor viewing, the TX15 MAX carries a 3.5-inch IPS touchscreen. It offers 262k color resolution and 600 nits brightness, so you can read the screen easily under direct sunlight.
In terms of controls, it features AG02 CNC aluminum gimbals in anodized red, black or gold. It also includes upgraded aluminum buttons, a scroll wheel and a carbon-fiber-look shell for a premium hand feel. In addition, RGB LED lights around the gimbals support customizable lighting via LUA scripts.
Extra Practical Functions & Options
On top of that, this radio adds advanced cooling, USB-C charging, SIM connectivity and fast firmware updates. It also delivers rapid memory access for consistent top-tier performance.
Furthermore, extra replacement switches are included. You may replace shoulder buttons with momentary or two-position latching switches if you prefer traditional switches. If you want a baseline version instead, check out the TX15 Standard.
