The ERA 5″ Frame Kit O4 is a new variant designed to house the DJI O4 Air Unit Pro, taking your flying experience to the next level. This frame retains the best features of the original ERA while introducing key enhancements:
O4 Nylon Camera Cage: Specially designed to accommodate the larger DJI Air Unit O4 camera, crafted from high-quality nylon using advanced additive manufacturing techniques.
O4 Bottom Plate Front: A larger bottom plate crafted from carbon fiber to ensure a perfect fit for the new O4 Nylon Camera Cage.
Updated 3D Prints: O4 VTX Dual Antenna Holder, New TPU Camera Inserts
If you already own an ERA Frame Kit, you can upgrade to the O4 with this conversion kit.
With the cage's quick swap function, you can install or remove your action camera effortlessly with just one screw. The mount offers a fixed 20-degree angle, customizable with different mounts.
The compressed X frame design provides exceptional stability and responsiveness for pitch and roll, ensuring precise control. Its split deck design reduces weight while maintaining durability.
A frame developed by pilots for pilots.
Important Notes:
This cage is crafted from high-quality nylon through additive manufacturing. While it provides solid protection, it’s not as robust as the current injection-molded cage.
ELRS Antenna Holder, Action Cam Mounts, and Electronics are not included.
For customers outside the EU: Price does not include tax.
