The HDZero Halo Stack combines the Halo H7 Flight Controller and Halo 4in1 70A ESC into a race-ready powertrain built for competitive racing and freestyle pilots. With a plug-and-play design and no soldering required for RX, VTX, or ESC connections, it's the fastest way to build a professional-grade FPV quad.
Available in two versions:ICM42688 + AM32 or ICM42688 + BLHeli32 — choose the ESC firmware that fits your flying style.
Halo Flight Controller Highlights:
H7 processor for fast, responsive flight control
Integrated Gemini true diversity ELRS receiver — no separate RX needed
TXCO-enhanced ELRS stability in high-heat race environments
Switchable 9V/3A BEC for HDZero VTX, controllable via Betaflight
5V/4A BEC supports full competition LED setups
Optimized for low-profile stacking with the HDZero Race v3 VTX
