RadioMaster TX15 ELRS Radio Controller

RadioMaster TX15 is an EdgeTX radio transmitter built around a dual-band ExpressLRS system (2.4GHz and 900MHz Sub-G on one LR1121 module), for pilots who want long-range reliability alongside fast racing and freestyle response.

Key features

• Dual-band LR1121 ELRS transceiver switches between 2.4GHz and 900MHz Sub-G for close-range low-latency flying or long-range links, with no external module needed.
• 3.5-inch 480x320 IPS touchscreen at 600 nits stays readable in direct sunlight and runs EdgeTX's touch-friendly menus.
• V5.0 Hall-effect gimbals give drift-free, wear-resistant stick input, with swappable momentary or latching shoulder switches.
• An STM32 H7 chip drives fast model switching and script execution, backed by built-in flash storage plus a microSD slot for scripts, sounds and themes.
• A built-in motion sensor enables TiltX/TiltY control for camera pan/tilt or switch triggers with a tilt of the radio.
• Runs on a 2S LiPo, two 18650 cells or a 21700 pack (batteries not included), with USB-C charging and firmware updates.
