iFlight BOB57 O3 Frame Kit

The iFlight BOB57 O3 is a hybrid cinematic freestyle frame designed in collaboration with pilot EllisvanJason. Bridging the gap between agile 5-inch freestyle quads and long-range 7-inch cruisers, it delivers the stability required for carrying full-size action cameras while retaining sharp flight characteristics. This edition is engineered specifically for the DJI O3 Air Unit, incorporating vibration-isolated camera plates and a lengthened chassis layout that keeps propellers out of your high-definition wide-angle feed.

Key features

• Optimised for 5.7-inch and 6-inch propellers to balance freestyle responsiveness with mid-range cruising efficiency.
• Thick 6mm arms arranged in a squashed-X geometry to maintain frame rigidity and support clean tuning profiles.
• Native DJI O3 integration featuring dedicated TPU mounting to isolate the camera from motor resonance.
• Extended central chassis to accommodate dual-stack setups alongside secure rear VTX placement.
