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

The HGLRC Specter 15A ELRS AIO combines an F411 flight controller, a 15A 4-in-1 ESC and a built-in ELRS receiver on one 42.5 × 42.5mm board. Built for 2–4S power systems, it strips wiring and weight from 75–85mm whoops and 2–3-inch toothpick builds.

Key features

• Onboard serial ELRS receiver with an IPEX antenna seat — no separate receiver to solder or mount.
• MPU6000 gyro on an F411 MCU running ZEUSF4EVO firmware, with the ESC pre-flashed to Bluejay.
• 15A continuous / 18A peak (10s) per motor, supporting Dshot300, Dshot600, Oneshot and Multishot.
• Standard 25.5 × 25.5mm mounting pattern used by most modern whoop and toothpick frames.
• 8MB onboard blackbox for flight-log recording.

Confirm your frame supports a 25.5 × 25.5mm FC footprint before ordering; the onboard receiver frees a UART for an external VTX or camera control link.
