HGLRC SPECTER 60A 4in1 ESC 3-6S BL32 128K with Heat Sink for FPV Racing Drone Freestyle

The HGLRC SPECTER 60A 4-in-1 ESC controls four brushless motors from a single compact board, designed for 3–6S LiPo FPV racing and freestyle drones. Running BL32 firmware on an STM32G071 128K processor, it delivers high-frequency motor control, integrated telemetry and an integrated CNC heat sink — all in a 20×20mm mounting footprint.

Four-Motor Control

Each of the four channels supports 60A continuous current and 65A peak current for 10 seconds, providing ample headroom for demanding racing and freestyle flight without requiring separate ESCs per motor.

BL32 128K Processor

The STM32G071 128K processor runs BL32 firmware (SPECTER60_G_128) and supports a PWM frequency of up to 128K, enabling precise and responsive motor control in compatible flight-controller configurations.

Motor-Control Protocols

Supported protocols include DShot600, DShot300, DShot150, OneShot125, OneShot42 and MultiShot, ensuring broad compatibility with current and legacy flight controllers.

Telemetry & Current Monitoring

An integrated current meter and BL32 telemetry allow the ESC to return real-time motor speed, current draw and temperature data to a compatible flight controller, supporting informed tuning and monitoring.

Heat & Environmental Protection

The integrated CNC heat sink improves thermal dissipation during sustained high-current operation. A six-layer PCB and nano-scale protective coating provide additional resistance to moisture and corrosion.

Compact Installation

At 44 × 36 × 7mm and 19.5g, the ESC uses a standard 20 × 20mm M3 mounting pattern, fitting directly into the majority of racing and freestyle FPV frames.
