DiFly Nano RX ELRS 755-950 MHz Receiver – FPV Drone Receiver from Ukrainian Manufacturer DiFly

DiFly Nano RX ELRS 755-950 MHz — a compact, lightweight, and highly sensitive receiver for FPV drones from the Ukrainian company DiFly. The device is designed for long-range flights, aerial photography, and complex freestyle tricks where stable and reliable communication over long distances is required.

Device Overview

The receiver operates in the 755-950 MHz frequency range, ensuring good diffraction and signal penetration in interference conditions. The DiFly Nano RX ELRS is equipped with two T-antenna options: one 180 mm long (tuned to approximately ~750 MHz), and the other 155 mm long (covering the entire 755-950 MHz range). Both antennas have IPEX1 (uFl) connectors. Telemetry is transmitted with 50 mW power, allowing for stable feedback over significant distances.

Key Advantages

• 755-950 MHz frequency range for better signal penetration and flight range.
• Two antenna variations (180 mm and 155 mm) for optimal selection based on drone configuration.
• Ergonomic component placement simplifies soldering and installation.
• Compact size and low weight — only 0.6 g without antenna, which is important for lightweight FPV quadcopters.
