DJI O4 Wide Air Unit (Lite) on a 2-Inch FPV Frame

Yes, a 2-inch FPV frame can be designed around DJI O4 Wide Air Unit (Lite). The hard part is not simply making the camera physically fit. A small frame has very little room for the camera, video hardware, battery, receiver, wiring and prop clearance, so the entire layout has to be designed around mass, protection and airflow.

• Camera fit and protection: the camera needs a secure mount without becoming the first thing that hits the wall.
• Center of gravity: moving video hardware a few millimeters matters far more on a micro build than on a 5-inch quad.
• Prop clearance: a frame designed for 2.2-inch props needs real clearance at full blade diameter, not just enough room for a 2-inch prop.
• Wiring space: compact does not mean crushed. Power, video and receiver wiring still need clean routes.
• Cooling: digital video hardware needs airflow instead of being buried inside a solid TPU box.

The Funkolius Impetus 2 is a T700 carbon 2-inch-class frame designed to accept up to 2.2-inch props. Its camera arrangement supports DJI O4 Wide Air Unit (Lite) as well as Walksnail, HDZero and analog configurations, depending on the camera and mount used.

On a micro quad, moving from 2.0 to 2.2 inches is a meaningful change in swept area. You cannot assume a frame intended for 2-inch props has safe clearance for 2.2-inch blades. Motor spacing and arm geometry have to be built around it. The Impetus 2 was designed with that clearance from the start.

The clean way to build a digital micro is to choose the frame, video system, motor pattern, battery voltage and prop diameter as one system. Trying to bolt O4 Lite onto a frame that was never laid out for the hardware usually creates compromises in protection, balance or serviceability.
