ESC 4in1 HDZero Halo 70A AM32 3-8S

Product detailed description

ESC 4in1 HDZero Halo 70A AM32 3-8S

The HDZero Halo 70A AM32 4-in-1 ESC (3–8S) is engineered for pilots who demand maximum reliability, clean power, and elite-level throttle performance. Designed around a robust split-board architecture, it isolates the control and power sections for significantly improved thermal handling and crash resilience.
With an integrated copper bus bar, 8-layer PCB, and 3oz copper per layer, this ESC delivers rapid current transfer, reduced voltage sag, and exceptionally sharp burst response—perfect for competitive racing and high-energy freestyle.

Capable of sustaining over 70A per motor channel and handling 100A bursts, the Halo ESC ensures stable, clean power delivery while protecting critical components from voltage spikes that can cause flight-controller lockups, MOSFET failures, and motor burns.

Features:
- Built for maximum performance and durability in race and freestyle drones
- Split-board architecture with copper bus bar for optimized burst throttle response
- 8-layer PCB with 3oz copper per layer and 24 MOSFETs
- Exceptionally clean power delivery protects flight controller from voltage spikes
- Conformal coating for moisture, dust, and corrosion protection
- Dual-sided motor solder pads for flexible builds
