iFlight Borg 5S RX Flight Controller

The iFlight Borg 5S RX integrates an onboard 2.4GHz ELRS receiver directly into the flight controller, streamlining freestyle and racing drone builds. Engineered specifically for 5S power systems, this board eliminates the need for an external receiver, saving physical space in the stack and freeing up a UART for other peripherals like a GPS or HD video system.

Key features

• Standard 30.5x30.5 mm mounting footprint fits most full-sized 5-inch frames.
• Internal ELRS routing frees up external UART ports and reduces total soldering points.
• Delivers high-refresh-rate, low-latency control hardware out of the box without finding mounting space for separate receiver boards.

Specifications

• Input voltage: 5S LiPo
• Mounting pattern: 30.5x30.5 mm
• Onboard receiver: ELRS (2.4GHz)

This flight controller is suited for pilots building dedicated 5S rigs who want to minimise component count and keep their wiring layouts as clean as possible.
