HGLRC Specter 15A ELRS AIO 2-4S 4-in-1 Flight Controller

The HGLRC Specter 15A ELRS AIO streamlines your micro build by integrating the flight controller, a 15A 4-in-1 ESC, and a built-in ELRS receiver onto a single board. Designed for 2-4S power systems, this AIO reduces wiring complexity and overall weight, making it highly effective for 75mm to 85mm FPV whoops and lightweight 2-inch to 3-inch toothpick frames.

Key features

• Combines the FC, a 15A ESC, and an onboard ELRS receiver to eliminate external receiver mounting and soldering.

• Supports 2-4S LiPo input voltage, offering flexible power delivery for high-kV micro brushless motors.

• Uses the industry-standard diagonal 25.5x25.5mm mounting pattern found in most modern whoop and toothpick frames.

Specifications

• Input voltage: 2-4S LiPo

• ESC continuous current: 15 A

• Onboard receiver: ELRS

• Mounting pattern: 25.5x25.5 mm

Before purchasing, confirm your frame supports a 25.5x25.5mm flight controller footprint. The integrated receiver provides a reliable, low-latency control link while freeing up a UART for an external VTX or camera system.
