iFlight Borg 5S RX Stack with Built-in ELRS Flight Controller + 60R 60A 4-in-1 ESC for Racing FPV Drones (4–8S)

Overview

The iFlight Borg 5S RX Stack combines the Borg 5S RX Flight Controller with the high-performance Borg 60R 4-in-1 ESC, creating a compact and powerful electronics system tailored for racing FPV drones. Designed for pilots who demand precision, stability, and reliable signal performance, this stack integrates a built-in ExpressLRS 2.4GHz receiver, advanced FPC-to-ESC connectivity, and support for up to 8S LIHV batteries.

With onboard 12V BEC switching, wide protocol compatibility (DJI MSP / HDZero / IRC Tramp / SmartAudio), and up to 60A continuous current per motor, this stack is the perfect solution for 5-inch and high-voltage racing builds.

Changelog – April 9, 2025: FC Dimensions updated from 34×28.5mm to 34×27mm.
