The iFlight Helion Pro O4 is a 10‑inch, long‑range FPV flagship co‑developed with 2RAW and built around DJI’s O4 Air Unit Pro. It pairs an aerodynamic quick‑release aero‑shell with a rigid 2RAW truss‑arm frame, premium 2RAW Thunder H7 flight controller and BLITZ E55 55A ESC, and a front‑mounted O4 camera for unobstructed framing. GPS is pre‑installed for safer long‑range flights (Betaflight GPS Rescue ready), and an external USB‑C port allows FC access without opening the shell. The O4 system delivers 4K/120fps recording and up to 15 km video transmission (FCC) with compatible goggles, making the Helion Pro O4 a purpose‑built platform for efficient cruising, stability in wind, and cinematic long‑range capture.

Advantages

  • Long‑range optimized 10‑inch platform with truss‑arm rigidity for high strength‑to‑weight and torsional resistance. ([iflight.com](https://www.iflight.com/en-Helion-pro.html?utm_source=openai))
  • Quick‑release aero‑shell streamlines airflow and protects the drivetrain while allowing fast maintenance access. ([iflight.com](https://www.iflight.com/en-Helion-pro.html?utm_source=openai))
  • Front‑mounted DJI O4 Air Unit Pro enables unobstructed framing and stabilized 4K/120 capture with 10‑bit D‑Log M. ([iflight.com](https://www.iflight.com/en-Helion-pro.html?utm_source=openai))
  • Premium electronics stack (2RAW Thunder H7 + BLITZ E55 55A) for low electrical noise and smooth flight. ([iflight.com](https://www.iflight.com/en-Helion-pro.html?utm_source=openai))
  • GPS pre‑installed and Betaflight GPS Rescue mode ready for safer long‑distance flying. ([shop.iflight.com](https://shop.iflight.com/Helion-Pro-O4-6S-HD-Pro2313%3Fsrsltid%3DAfmBOorUv8Wm9F1xS6YbqGHzKzERutx8l7IOOk6h-AUw8NagKLIi_on4?utm_source=openai))
  • External USB‑C port for configuration without removing the shell; no props in view even with action cam at zero degrees. ([iflight.com](https://www.iflight.com/en-Helion-pro.html?utm_source=openai))

Disadvantages

  • Larger, heavier 10‑inch airframe requires spacious flying areas and high‑capacity 6S batteries; not ideal for tight freestyle or indoor use. (General operational consideration.)
  • Quoted high‑speed cruise endurance (8–9 min at ~80 km/h) is shorter than hover time—typical for long‑range platforms at sustained speed. ([shop.iflight.com](https://shop.iflight.com/long-range-quads-cat325/Helion-Pro-O4-6S-HD-Pro2313?utm_source=openai))
  • DJI O4 RockSteady stabilization limits FOV to “Standard” when enabled; use Gyroflow or disable EIS if you need wider FOV. ([dji.com](https://www.dji.com/mc/o4-air-unit/specs?utm_source=openai))
  • 5.1/5.8 GHz operation and 15 km range figures are subject to regional regulations and environment; always comply with local laws. ([dji.com](https://www.dji.com/mc/o4-air-unit/specs?utm_source=openai))
