HDZero Halo 4in1 70A ESC (AM32)

Engineered by HDZero — a leader in high-performance FPV technology — the Halo 4in1 70A ESC is built for racers and freestyle pilots who demand uncompromising power and reliability. With a split-board architecture, copper bus bar, and 8-layer PCB using 3oz copper per layer, it delivers sharp throttle response, minimal voltage drop, and exceptional heat dissipation. Even under extreme load or crashes, it ensures stable and clean power delivery.

• Split-board design separating control and power stages for better heat performance
• 8-layer PCB with 3oz copper per layer and integrated copper bus bar for optimized burst response
• Clean power delivery protects the flight controller and prevents voltage drop
• Conformal coating for moisture, dust, and corrosion resistance
• Dual-sided motor pads for flexible wiring
• AM32 firmware for smoother throttle and advanced tuning options
