Note: RockSteady fails in some turning scenarios(Gyroflow no problem)

Feature

1. 155° Wide FOV Upgrade: Directly fixes O4 Lite’s narrow field of view—155° ultra-wide angle eliminates blind spots, delivering immersive visuals for racing, freestyling, and exploration flights.
2. FLYWOO×Runcam Co-Developed Quality: Jointly engineered by two FPV leaders, retains O4 series’ signature clarity/reliability while solving core limitations—no vignetting (dark corners) and sharp image edges (outperforms O4 Lite’s partial vignetting/blurry edges).
3. Plug-and-Play Ready: Fully modified and pre-tuned for focus by FLYWOO—no extra setup required, install and fly out of the box, perfect for FPV enthusiasts upgrading their system.
4. Lightweight Multi-Adapter Fit: Weighs just 10.9g (12.5g with 18mm adapter /14.6g with 20mm adapter), adding minimal payload to preserve drone nimbleness; compatible with 18mm/20mm cam mounts for flexible DIY setups.
5. Professional Stabilization Compatibility: Works seamlessly with Gyroflow (solves RockSteady’s partial turning scenario limitations), meeting the needs of pro pilots for stable, high-performance FPV footage.
6. Rigorous Factory Testing: Each unit undergoes full quality checks by FLYWOO, ensuring consistent performance—ideal for both upgrade users and those replacing damaged air units.
