RadioMaster XR4 Gemini Xrossband Dual-Band ELRS Receiver

RadioMaster XR4 Gemini Xrossband Dual-Band ExpressLRS Receiver is a dual-band ELRS receiver designed for pilots who want maximum link resilience on long-range builds or RF-noisy flying sites. Its Gemini Xrossband architecture listens on two frequency bands at the same time, adding redundancy beyond a single-band receiver and helping maintain control when one band is compromised.

Key features

• Gemini Xrossband dual-band reception: simultaneously listens on two ELRS bands for redundancy.

• True diversity reception: uses diversity to improve link stability when antenna orientation or multipath changes.

• ExpressLRS ecosystem: intended for ELRS transmitters and ELRS-based control links used in modern FPV builds.

• Receiver class: built specifically for RC control (not video), suitable for quads, wings and long-range platforms that prioritise link robustness.

Choose this receiver if you are already committed to ExpressLRS and want a redundancy-focused RX for critical flights; pair it with an ELRS radio module/tx capable of Gemini/Xrossband operation to benefit from the dual-band design.
