RadioMaster XR1 Nano Multi-Frequency ExpressLRS Receiver – Ultra Compact Long Range ELRS RX

RadioMaster XR1 Nano Multi-Frequency ExpressLRS Receiver

The RadioMaster XR1 Nano is an ultra-compact, high-performance ExpressLRS (ELRS) receiver designed for pilots who need both flexibility and extreme reliability. By integrating the cutting-edge Semtech LR1121 transceiver, the XR1 offers exceptional sensitivity and range, whether you are flying in the standard 2.4GHz band for racing or switching to 900MHz for long-range exploration. It’s a versatile "do-it-all" receiver that fits into even the tightest micro-drone builds.

Why Pilots Choose the XR1

What makes the XR1 truly special is its Multi-Frequency capability. In the past, you had to choose between 2.4GHz and 900MHz when you bought your receiver. The XR1 changes the game by giving you the hardware to operate across bands, making it a perfect fit for pilots who fly everything from high-speed racing quads to massive, cinematic long-range rigs. It’s lightweight, robust, and designed to perform under the toughest conditions.
