iFlight Borg 5S RX Stack with Built-in ELRS 2.4GHz FC + 60RS 60A 4-in-1 ESC for Racing FPV Drones (4–8S)

Overview

Introducing the iFlight Borg 5S RX Stack, a high-performance flight control system purpose-built for FPV drone racing. Featuring the all-new Borg 5S RX Flight Controller paired with the Borg 60RS 60A 4-in-1 ESC, this stack delivers seamless integration, minimal latency, and unmatched power handling — all in a compact 20×20mm mounting footprint.

The FC comes with a built-in ELRS 2.4GHz receiver and integrated antenna, while also offering support for external receivers and antennas. It supports up to 8S LIHV input, features a 12V BEC with VTX switching, and ensures robust signal reliability through FPC + SH1.0 connectors. When paired with the 60RS ESC, this system becomes a top-tier solution for aggressive freestyle or competition-level racing drones.
