XR4 Gemini Xrossband Dual-Band ExpressLRS Receiver

The XR4 Gemini is what happens when ExpressLRS goes full sci-fi. Dual-band 2.4GHz + 900MHz, antenna diversity, and nano form factor all wrapped into one ridiculously capable receiver. It’s designed for pilots who want long-range confidence and race-grade latency without swapping hardware. Basically, the XR4 Gemini is your control link’s insurance policy—minus the boring paperwork.

Why You Want It

Because failsafes are only entertaining when you’re watching someone else’s quad cartwheel into the horizon. The XR4 Gemini leverages crossband dual-frequency ExpressLRS, constantly choosing the stronger signal for buttery-smooth control. That means you can rip close-range at 2.4GHz, dive into long-range at 900MHz, and never worry about your quad suddenly going deaf mid-pack. It’s the kind of tech that makes you wonder how you ever trusted a single-band RX.

Specifications

What’s in the Box*

• 1× XR4 Gemini ExpressLRS Receiver
• 2× Antennas (diversity isn’t optional here)

Disclaimer

Yes, antennas are included—because shipping just the PCB would be cartoon-villain behaviour.

Still Here?

You’re clearly the type who wants zero excuses when flying. The XR4 Gemini gives you crossband dual-frequency ELRS, antenna diversity, and nano weight in one absurdly capable package. Add it now and start flying like failsafes were just a bad dream.
