Oh good, another tiny rectangle that promises not to lose signal when you push your long-range setup past the point of sanity. The BAYCKRC C3 Dual Band Nano RX is here to cure your chronic video freeze and tumbling-from-the-sky syndrome. Packing the LR1121 chip, this ultra-light ELRS receiver hops between 868MHz/900MHz and 2.4GHz frequencies. Whether you’re a long-range explorer testing the curvature of the earth or a micro drone goblin threading the tightest gaps at your local park, this receiver offers bulletproof link stability. Yes, it weighs less than a gram. No, that is not a hallucination.
Highlights
Dual Band Wizardry: Simultaneous support for 868MHz/900MHz and 2.4GHz frequencies means you get the range of a mountain goat and the latency of a caffeinated gamer.
TCXO Stability: Equipped with a Temperature Compensated Crystal Oscillator to prevent frequency drift when your electronics get hotter than your soldering iron.
Sub-Gram Weight: At just 0.8g (receiver only), you’ll forget it’s even on your 75mm whoop until you realize you still have control halfway across the field.
ESP32-C3 Power: Built on the ESP32-C3 platform for snappy processing and seamless ELRS firmware support.
Why You Want It
If you’re tired of your quad playing hide and seek without you, the BAYCKRC C3 Dual Band Nano RX is the ultimate upgrade. It’s tiny, aggressively reliable, and features TCXO precision so your connection stays locked tighter than your grip on the radio sticks during a dive. No more sweaty palms over signal degradation. Just bind, fly, and try not to hit a tree.

FAQ
What makes dual-band (900MHz and 2.4GHz) better for ELRS?
Dual-band capabilities allow pilots to utilize 900MHz for extreme long-range penetration and obstacle reflection, while seamlessly switching to 2.4GHz for high-speed, low-latency acrobatic flying.
Do I need a TCXO receiver for FPV?
You don’t strictly *need* it until you’re pushing massive distances or flying in extreme temperature shifts. A TCXO (Temperature Compensated Crystal Oscillator) prevents frequency drift, keeping your ELRS link locked without rand
