iFlight BOB57 O4 Pro Cinewhoop Frame Kit

The iFlight BOB57 O4 Pro is a 5-inch frame kit engineered for professional cinematic flying and direct integration with the DJI O4 Pro digital transmission system. Utilising a signature Bob-style ducted layout, this frame provides the protective benefits of a cinewhoop while delivering the thrust authority needed to carry heavier camera payloads safely in close proximity to subjects.

Key features

• Includes custom-moulded TPU mounts specifically dimensioned to secure the DJI O4 Pro air unit and camera.
• Bob-style aerodynamic ducted configuration provides comprehensive propeller protection while minimising airflow turbulence.
• Built with rigid carbon fibre main plates and impact-resistant TPU components to isolate high-frequency vibrations from the flight controller.

Specifications

• Supported Propeller Size: 5 inches
• Frame Layout: Ducted cinewhoop
• Construction: Carbon fibre and TPU
• Digital Integration: DJI O4 Pro

When assembling this kit, pair it with high-torque motors and a robust 6S LiPo to compensate for the added weight of the prop guards. The frame is tailored strictly for the DJI O4 Pro ecosystem, ensuring precise camera fitment and adequate cooling airflow for the high-power video transmitter.
