Stack HDZero Halo H743 ICM42688 70A BLHeli_32

Product detailed description

Stack HDZero Halo H743 ICM42688 70A BLHeli_32

The HDZero Halo Stack (ICM + BLHeli_32) is a high-performance 20×20 powertrain that pairs the Halo H743 ELRS Flight Controller (ICM42688 gyro) with the Halo 70A BLHeli_32 4-in-1 ESC. Engineered for competitive racing and freestyle, this stack delivers extreme reliability, clean power, and ultra-responsive control — all with a plug-and-play wiring system that makes building effortless.

Developed by HDZero, this stack is optimized for digital FPV and designed to integrate seamlessly with the HDZero race ecosystem. With minimal wiring, true-diversity Gemini ELRS, copper bus-bar power distribution, and premium 8-layer PCB construction, the Halo Stack gives pilots a professional-grade setup that’s easy to build, easy to tune, and built for hard competition.

Features:
- Complete plug-and-play stack — no soldering for RX, ESC, or HDZero VTX connection
- ICM42688 gyro for stable, high-resolution flight performance
- True Diversity Gemini ELRS receiver built in (2xSX1280)
- TXCO-stabilized ELRS for consistent RF performance in hot race conditions
- H743 processor (480MHz) for ultra-fast control loop response
- 70A BLHeli_32 ESC with 8-layer PCB & 24 MOSFETs
- Copper bus-bar architecture for superior burst throttle handling
- Exceptionally clean power — protects FC from voltage spikes
- Conformal coating for moisture, dust & corrosion resistance
- Dual-sided motor pads for flexible, repair-friendly builds
- Optimized for HDZero digital stacks with a low-profile footprint
