HDZero Halo Stack – Flight Controller + 4in1 70A ESC

The HDZero Halo Stack combines the Halo Flight Controller and Halo 4in1 70A ESC into a race-ready powertrain, engineered by HDZero—leaders in high-performance digital FPV systems. Designed for power, reliability, and ease of assembly, this stack is the ultimate solution for competitive racing and freestyle pilots.

With its clean layout, minimal wiring, and integrated components, the HDZero Halo Stack is the easiest way to build a professional-grade racing drone—without sacrificing performance, reliability, or serviceability.

At its core is the Halo 4in1 70A ESC, built for extreme durability and responsive throttle. A split-board design separates control and power stages, improving thermal performance and crash resilience. With 24 MOSFETs across an 8-layer PCB using 3oz copper per layer and a rear-mounted copper bar, the Halo ESC delivers exceptional burst throttle response with minimal voltage drop. Rated for 70A continuous per motor and 100A bursts, the ESC supplies clean, stable power while protecting sensitive electronics from voltage spikes. A conformal coating adds moisture, dust, and corrosion resistance. Choose between BLHeli32 or AM32 firmware based on your preference.

The Halo Flight Controller simplifies your build while delivering professional-grade control. Powered by an H7 processor, it integrates a Gemini true diversity ELRS receiver, using dual independent receivers for rock-solid control link stability. A TXCO (temperature-compensated crystal oscillator) maintains consistent ELRS performance even in extreme temperatures—essential for race conditions.

The integrated ELRS RX not only simplifies quad assembly but also provides a cost-effective solution. With the Gemini ELRS RX typically priced at $25, this combination represents significant savings compared to purchasing separate ELRS receivers and flight controllers.

Built for digital video systems, the Halo eliminates the analog OSD chip to reduce costs and save space. It is specifically designed to allow the HDZero Race v3 VTX to stack on top of it in a low-profile manner, resulting in a durable and compact stack height. This optimization ensures a secure, space-efficient build while maintaining excellent performance.

The Halo FC requires no soldering for VTX, receiver, or ESC connections. Everything plugs directly into dedicated sockets using included cables, making assembly and field repairs fast and frustration-free. This low-profile, modular design results in a tidy, durable racing stack.

The switchable 9V BEC powers your HDZero VTX, with remote control over power via Betaflight to simplify pit stops and extend VTX lifespan. A separate 5V/4A BEC is capable of powering an entire competition-grade LED setup without the need for external regulators.

The Halo Flight Controller is available in two versions, MPU6000 and ICM42688, to meet different pilot preferences.

HDZero Halo Stack – 飛控 + 4合1 70A 電調

HDZero Halo Stack將Halo 飛控和Halo 4合1 70A 電調整合於一體，打造出一套專為競速而設計的動力系統，由高性能數位FPV系統領域的領導者 HDZero 傾力打造。這款套裝兼具強勁動力、可靠性和易組裝性，是競技競賽和自由飛行愛好者的理想之選。

HDZero Halo Stack 佈局簡潔，佈線極少，組件集成，是打造專業級競速無人機的最簡單方法——而且不會犧牲性能、可靠性或可維護性。

其核心是Halo 4合1 70A電調，專為極致耐用性和靈敏的油門響應而設計。分離式電路板設計將控制級和功率級分離，從而提升散熱性能和抗衝擊能力。 Halo電調採用8層PCB，每層使用3盎司銅，並配備24個MOSFET，以及後置銅條，可在極低電壓降下提供卓越的瞬時油門響應。此電調額定電流為每馬達70A持續電流和100A瞬時電流，可提供純淨穩定的電源，同時保護敏感電子元件免受電壓尖峰的影響。此外，其表面塗層也增強了防潮、防塵和防腐蝕性能。您可以根據個人喜好選擇BLHeli32或AM32韌體。

Halo 飛行控制器簡化了您的組裝流程，同時提供專業級的操控性能。它採用H7 處理器，整合Gemini 真分集 ELRS 接收器，使用雙獨立接收器確保控制連結的穩定性。 TXCO （溫度補償晶體振盪器）即使在極端溫度下也能保持 ELRS 性能的穩定——這對於比賽環境至關重要。

整合式ELRS接收機不僅簡化了四軸飛行器的組裝，而且提供了經濟高效的解決方案。 Gemini ELRS接收機的售價通常為25美元，與單獨購買ELRS接收機和飛控相比，這種組合可以節省大量成本。

Halo專為數位視訊系統而設計，它取消了類比OSD晶片，從而降低成本並節省空間。它經過專門設計，可使HDZero Race v3 VTX以低矮的方式堆疊在其上方，從而實現穩固且緊湊的堆疊高度。這種優化確保了安全、節省空間的建置方式，同時保持了卓越的效能。
