Overview:
The HDZero Halo 4in1 70A ESC 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. Especially optimised to sharpen burst throttle response and minimise voltage drop during aggressive manoeuvres.
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.
Tested to the limits, this ESC was built to outlast others. Every detail, from the conformal coating that protects against moisture and dust to the dual-sided solder pads for flexible builds, reflects HDZero's commitment to durability and field reliability.
Available in BLHeli32 or AM32 firmware versions, the Halo ESC allows you to choose the experience that best suits your style.
