HDZero Halo 4in1 70A ESC – Split-Board Design, 3S–8S

The HDZero Halo 4in1 70A ESC is built for pilots who refuse to compromise on power or reliability. A split-board architecture separates the control and power stages for better thermal performance and crash resilience, while a copper bus bar and 8-layer PCB with 3oz copper per layer sharpen burst throttle response and minimize voltage drop during aggressive maneuvers.

With 24 MOSFETs (6 per motor), 70A continuous per motor and 100A burst capability, it delivers clean, stable power while isolating voltage spikes from the MCU and drivers — helping prevent brownouts, burnt motors, and MOSFET failures.

Currently available in BLHeli32 — AM32 version coming soon.
