It comes with the O4 Transmitter and Lens.
Description:

For FPV pilots frustrated by the O4 Lite’ s narrow field of view, the solution is here: the O4 Wide Air Unit. Developed jointly by FLYWOO and Runcam, it directly addresses this key limitation while maintaining the O4 series’  clarity and reliability.

Each unit is fully modified and tested by FLYWOO, with pre-tuned focus — ready to install and fly out of the box. Get a wider, more immersive view instantly, whether racing, freestyling, or exploring. No setup required. Perfect for FPV enthusiasts looking to upgrade their flight experience.

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.
