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.

    No problems after a year and a half
    Color: Dogwood & Calming, Size: Medium
    Have been regularly buying these for my corgi for about a year and a half. The 2 pack lasts about a month or 2 each time. Pieces break off in small enough pieces that they safely pass through his digestive system. He gnaws each one down to about 1/4 the original size before we take it away and give him a new one. He continues to have regular bowel movements and has a healthy appetite so I can’t imagine any problems arising after so long. I have tried other alternatives and every other similar chew breaks off in larger pieces and didn’t feel comfortable letting him chew/eat them. I noticed there are a few 1 star reviews saying their dogs got sick off these but after a year and a half I have had 0 issues with this product. I guess it depends on the dog and how big of pieces they are swallowing. My dog ingests pieces about the size of a grain of rice so just pay attention and you should be fine.

    Long lasting and safer alternative to sticks
    Color: Dogwood & Calming, Size: Medium
    These are great, very durable, and have lasted a very long time. Much safer for my dogs than the random sticks they find in the yard. They do get shorter with chewing eventually, but they don't break off in little chunks like I've seen with some nylon chews, and they don't splinter like wood. Medium size works well for both my 16 lb Cavalier and my 60 lb Pyrenees/Golden mix. They're both moderate-to-aggressive chewers, though size obviously affects how much damage they can do. I wish you could buy the hemp chew separately because that one is very much a favorite in my house, so after 2 years and 2 purchases, I have barely any left of the remaining hemp chew, but still 2 of the dogwood chews that neither dog is as interested in anymore. I'd love to buy a couple more of just the hemp one.

    Your dog will thank you.
    Color: Dogwood & Fresh Breath, Size: Large
    My dogs loves to chew on these. They make a small mess but not as bad as other chews. They are food for keeping teeth clean.

    Nice chew toy
    Color: Dogwood Mushroom, Size: Medium, Color: Dogwood Mushroom, Size: Medium
    Super durable and puppy loves it. It was a bit hard for her at first but now at 5 months it’s one of her favorite things to gnaw on! It is heavy for the size but seems to be great quality and has given many hours of chew time with minimal wear.
