HDZero Halo 4in1 70A ESC

Built for maximum performance and durability in race and freestyle drones.

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.
