Engineered by HDZero – leaders in high-performance FPV technology, the Halo 4in1 70A ESC is designed for pilots who demand both power and reliability. Whether you're pushing limits in drone racing or freestyle, this ESC delivers unmatched durability and throttle response.

Check out the rest of our Electronic Speed Controllers and all our HDZero Products!

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.
  • Available in BLHeli32 or AM32 firmware versions, the Halo ESC lets you choose the experience that best fits your style.

    So much sturdy fun for little dogs!
    Size: Small 2"
    Wow! My puppy loves these! He is entertained endlessly chasing after and nose scooting the little rubber balls! He really seems to enjoy the jingle sound and loves to chew on the balls also. Even with a lot of chewing from his little teeth, there are no marks. Sturdy, great toy!

    Well made, perfect size!
    Size: Small 2"
    My dogs love these balls. They are the perfect size and hold up well for my 2 dogs, 7# and 9#. The bell is a nice change from the squeaky toys.
