What the Flylens 85 HD O4 is for
It works well for filming indoors and in tight spaces. The PC guards cover the propellers, and the camera damping platform reduces the vibrations that reach the video. Its reverse-thrust propeller layout and quick-release battery compartment help keep flight stable and make battery swaps fast.
Before buying, check that your goggles and radio are compatible with DJI O4 and with the DJI / PNP version.
O4 vs O4 Pro: which to choose
Both versions share the electronics and motors. The O4 is the lighter one: 68.8 g versus 87.5 g, and with a 1000 mAh battery it flies for about 9 minutes versus 6. The O4 Pro has a larger camera and is the one to look at if image quality is your priority.
