Engineered by HDZero, the Halo 4in1 70A ESC is built for pilots who demand maximum power, precision, and durability in racing and freestyle drones.
Its advanced split-board design separates control and power stages for improved heat management and crash resistance. An integrated copper bus bar and 8-layer PCB with 3oz copper ensure efficient current flow, reduced voltage drop, and sharper throttle response during aggressive maneuvers.
With 70A continuous current per motor (up to 30s) and 100A burst capability, the Halo ESC delivers consistent, clean power while protecting sensitive components from voltage spikes—reducing the risk of desyncs, brownouts, and hardware failure.
