DUAL RX ELRS 433MHz is a high-stability Extended Range receiver powered by the ESP32 MCU and supporting the CRSF protocol for seamless integration with modern flight controllers. Its compact size and low power consumption make it ideal for FPV drones and UAV platforms requiring reliable long-range telemetry.
🟩 We are a veterans’ team
We validate radio equipment in real-world operational environments: interference conditions, low-altitude flight, long-range telemetry stability and fail-safe behaviour under load.
