HGLRC SPECTER 90A Single ESC High-Performance Professional ESC

HGLRC SPECTER 90A Single ESC High-Performance Professional ESC

Product description

The HGLRC SPECTER 90A Single ESC is a professional, high-performance ESC designed for demanding FPV drones, long-range helicopters, and heavy-lift builds. With a continuous current of 90A, a peak current of 100A, and support for 2–8S LiPo batteries, the ESC offers enormous power reserves for modern high-performance propulsion systems.

The robust, fully enclosed CNC-machined aluminum housing on both sides ensures excellent heat dissipation and reliably protects the electronics from dust, dirt, and mechanical stress. The powerful dual-MOSFET parallel circuit ensures stable operation even under high continuous loads.

Equipped with an STM32G071 microcontroller and BLHeli_32 firmware, the ESC supports modern control protocols such as DShot150, DShot300, DShot600, Oneshot, and Multishot. Thanks to integrated ESC telemetry, key operating data can be monitored in real time, while temperature protection provides additional safety.
