Radiomaster TX15 Radio Controller (ELRS / M2)

RadioMaster TX15 Radio Controller (ELRS / M2) is a modern FPV radio transmitter designed for drone pilots, RC hobbyists, and advanced users who need reliable control, smooth handling, and flexible open-source performance. Built with EdgeTX firmware and an integrated ExpressLRS system, the TX15 delivers fast response, strong signal performance, and a feature-rich control experience for FPV drones, fixed-wing aircraft, RC models, and simulator training.

The controller features a powerful STM32 H7 processor, giving it fast menu navigation, smooth model handling, quick script execution, and responsive overall performance. Its 3.5-inch IPS touchscreen with 480 × 320 resolution makes setup, model configuration, telemetry monitoring, and system control easier and more intuitive.

Equipped with V5.0 Hall sensor gimbals, the RadioMaster TX15 offers accurate stick control and smooth movement for precise flying. The M2 configuration makes it suitable for pilots who prefer Mode 2 layout, commonly used by FPV drone pilots for throttle control on the left stick.

The built-in ELRS transmitter module supports ExpressLRS protocol for low-latency and long-range radio control performance. Depending on the selected version, the TX15 is available with 2.4GHz or Sub-G 900MHz ExpressLRS, giving pilots flexibility for different flying styles and regional requirements.

The RadioMaster TX15 ELRS Radio Controller also includes useful features such as a cooling fan, built-in flash storage, USB-C connectivity, JR-compatible module bay, motion sensor, foldable antenna, interchangeable shoulder switches, and support for different battery options. It is a strong choice for pilots who want a powerful, compact, and customizable radio system for FPV and RC control.
