iFlight BOB57 O4 Pro Frame Kit

The iFlight BOB57 O4 Pro is a 6-inch cinematic long-range frame built around the DJI O4 Air Unit Pro. It sits between an agile 5-inch freestyle quad and a 7-inch cruiser: open propellers on a 278mm wheelbase and thick 6mm arms give it the stability to carry a full-size action camera without the drag of ducts.

Key features

• Sized for 6-inch propellers, bi-blade or tri-blade.
• Thick 6mm carbon arms for a rigid frame that tunes cleanly.
• Camera and VTX mounting for the DJI O4 Air Unit Pro.
• Open-prop layout — a cinematic long-range frame, not a ducted cinewhoop.
