HDZero Halo 70A 3S-8S 4IN1 ESC AM32 20x20mm

Do not forget to repin the cable!!!!

Highlights:

• 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—specially optimized to sharpen burst throttle response and minimize voltage drop during aggressive maneuvers.
• With continuous 70A output per motor channel (for up to 30 seconds) and 100A burst capability, the Halo ESC powers through demanding flights while protecting critical electronics with clean power delivery. Voltage spikes are isolated from the MCU and drivers. This vital protection helps prevent MCU brownouts or lockups—common culprits behind burnt motors, failed MOSFETs, and critical flight failures.
• Tested to the limits, this ESC was built to outlast others. Every detail, from the conformal coating to protect against moisture and dust, to the dual-sided solder pads for flexible builds, reflects HDZero's commitment to durability and field reliability.
• Fully supports ULTRA firmware (fast telemetry and OSD configuration!)
