    Detailed information

    Product detailed description

    The HDZero Halo 4in1 70A ESC AM32 is a high-end electronic speed controller designed for pilots who demand maximum performance and reliability. With HDZero’s advanced design and technology, it delivers exceptional durability, precise throttle response, and clean power for both racing and freestyle drones.

    Its split-board architecture separates the control and power stages for improved cooling and greater crash resistance. A copper bus bar and 3oz copper across eight PCB layers ensure rapid current flow, efficient heat dissipation, and minimal voltage drop during aggressive throttle changes.

    The ESC delivers a continuous current of 70 A per channel (for up to 30 seconds) and peak current of 100 A, handling even the most demanding flight conditions. Clean power delivery and voltage-spike isolation protect the flight controller electronics from brownouts or damage. A conformal coating shields against moisture, dust, and corrosion, while dual-sided solder pads allow flexible installation in various frame types.
