GEPRC MARK5 O4 Pro Frame
The GEPRC MARK5 O4 Pro is a 5-inch freestyle frame built to integrate seamlessly with the DJI O4 Air Unit Pro. The frame addresses high-frequency vibration issues through a redesigned camera mount and custom silicone shock absorbers, resulting in cleaner gyro data and smoother HD video. The structure uses 3K carbon fiber with 5.0mm arms and 2.5mm top and bottom plates. It features a quick-release arm mechanism that requires only two screws for fast replacements. The frame is available in a DeadCat (DC) configuration to keep propellers out of the camera view, and a Wide X configuration for balanced freestyle flight dynamics.
Key Features
- DJI O4 Pro Integration: Camera mounting and internal spacing are optimized directly for the DJI O4 Air Unit Pro module.
- Vibration Isolation: The redesigned camera mount utilizes custom shock-absorbing silicone to minimize high-frequency resonance.
- Geometry Options: Select DeadCat (DC) for cinematic flying without props in view, or Wide X for symmetrical freestyle performance.
- Quick-Release Arms: The structural design allows for rapid maintenance, requiring the removal of only two screws to swap an arm.
- Action Camera Ready: Includes two distinct TPU mounts to support a wide range of standard action cameras out of the box.
