Description
The HDZero Halo 70A 3-8S AM32 4-in-1 ESC - 20x20 is designed for pilots who demand both power and reliability. Whether you're pushing limits in drone racing or freestyle, this ESC delivers unmatched durability and throttle response. At the heart of the Halo ESC is a split-board architecture, separating the control and power stages for improved thermal performance and crash resilience. An integrated copper bar and 3oz copper across 8 PCB layers ensure rapid current flow and superior heat dissipation—specially optimized to sharpen burst throttle response and minimize voltage drop during aggressive maneuvers. With continuous 70A output per motor channel (for up to 30 seconds) and 100A burst capability, the Halo ESC powers through demanding flights while protecting critical electronics with clean power delivery. Voltage spikes are isolated from the MCU and drivers. This vital protection helps prevent MCU brownouts or lockups—common culprits behind burnt motors, failed MOSFETs, and critical flight failures.
