【HDZero】Halo 70A 4-in-1 ESC

The 【HDZero】Halo 70A 4-in-1 ESC is an Electronic Speed Controller.

HDZero Halo 4-in-1 70A ESC - Meticulously engineered by HDZero, a leader in high-performance FPV technology, the Halo 4-in-1 70A ESC is designed for pilots who demand robust power and exceptional reliability. Whether you're pushing the limits in drone racing or freestyle flying, this ESC delivers unparalleled durability and throttle response. At the core of the Halo ESC is a split board architecture, separating the control and power stages to enhance heat dissipation and impact resistance. Integrated copper bars and 3oz copper layers on an 8-layer PCB ensure rapid current transfer and superior thermal performance—specifically optimized to boost throttle response speed and minimize voltage sag during aggressive maneuvers. The Halo ESC provides a continuous current output of 70A per motor channel (up to 30 seconds), with a 100A burst capability, delivering robust power even during high-load flights while protecting critical electronic components through clean power output. Voltage spikes are isolated from the MCU and drivers. This crucial protection helps prevent MCU voltage drops or crashes—common causes of motor burnouts, MOSFET damage, and flight failures. This ESC is rigorously tested and designed to outperform the competition. From the conformal coating for moisture and dust protection to the double-sided pads for flexible builds, every detail reflects HDZero's commitment to durability and field reliability. The Halo ESC is available in BLHeli32 or AM32 firmware versions, allowing you to choose the experience that best suits your style.
